How to deploy client-side service WSDLs - wsdl

I have code using the SysOperationFrameworkService, and after a model-deploy or some other set of circumstances, many users get Function SysOperationDataContractInfo::newParameterInfo has been incorrectly called..
It's unable to be resolved with full-compile, sync, full CIL, deleting XPPIL files, deleting AUC/KTI, usage data, security (they're admin), refreshing caches (server &client), etc. and I have a ticket open with Microsoft and they're struggling.
I've narrowed the issue down to when the service group AxClient located in the AOT at \Service Groups\AxClient WSDL files get deployed to C:\Users\[User]\AppData\Local. Either those files existing there, or something happening when those files get deployed is needed.
Any idea how/what causes these files (AxClient.wsdl, etc) to be created? With a user who happens to be "working", I can close the client, delete all the files, open the client, and no files will exist...then I perform a SysOp process and those files get created during that process. With the non-working user, with same security on the same machine does it, the files don't get created.

I have found that the
"Function SysOperationDataContractInfo::newParameterInfo has been incorrectly called" has been throwed because of a possible bug in the kernel when calling the "dictMethod = new DictMethod(UtilElementType::ClassInstanceMethod, dictClass.id(), methodName);" in the SysOperationServiceController.getServiceOperation() method. In my case the new DictMethod was sometimes unable to get the method parameter from a superclass, causing the _parentMethodParameterName check fail in the SysOperationDataContractInfo.newParameterInfo.
So, I solved the issue just by doing an override of the super method where the parameter could not be retrieved and then just calling super(_parameter), then everything went well.

Have you tried axclicfg.exe -> connections -> refresh

`Unable to load the specified metadata resource` suddenly appears without code changes

PLEASE NOTE: None of the answers in the link above (which I don't seem to be able to remove) helped me. As I explain below, I had already tried all that stuff
I have a web site, developed in VS2013 using ASP.NET MVC5/WebAPI2, which has several related projects such as a service layer, repository layer, etc. Down at the bottom of the stack is a class library that holds an EF model. I have separated the actual entities into another class library, to allow them to be reused without requiring the model library.
All of this has been working fine. The web site was running, and I could make calls to the WebAPI methods as well.
I just uploaded the latest version to the production server, and all is working fine there. Then came back to VS to carry on work, and when I try to run up the web site, I get an exception
Unable to load the specified metadata resource
Searching around, it seems that the cure for this is to modify the connection string to point to the actual assembly name instead of using the default . I have two problems with this, first is that none of the config files in the solution have been touched today (by me at least, and the file history form source control confirms this), so there's no reason why it should suddenly stop working after being deployed, and second, even if I add the assembly name, I get the same exception.
Anyone any ideas what I can do? I'm completely stuffed now. Can't do anything.
Edit: I tried again to specify the assembly in the connection string, and now get the exception Unable to resolve assembly. I have checked the assembly name in a decompiler, and I'm pretty sure got it right.
Edit again: I just pulled the version that I deployed from source control, and that gives the same exception, so I'm sure this is nothing to do with any files I've changed (or even that have been changed by VS). The version on the production server is still working, but the source code that drives that exact same version gives the exception. So, I'm certain that the answer is NOT to be found in the myriad other versions of this question, but is somewhere else.
Found the problem, and am posting it here in the hope that it will help someone else, as I don't think this was clear in any of the other posts on this issue.
I have a layered solution, with the web project referencing a service layer, which references a repository layer which in turn references the model project. It seems to for EF to work, whichever layer actually causes the database to be accessed requires a reference to the model project. My service layer project, which was where ToList() was being called (thus enumerating the query, and causing the database to be hit) didn't have a reference to the model project, so was failing to load the assembly.
I didn't need to alter the metadata part of the connection string either, as once the service layer had a reference to the model project, it was able to find the resources by itself. Having said that, one thing I did learn from all of this is that you can speed up the creation of the model (slightly) by specifying the assembly containing the resources explicitly, as this saves the framework having to search through all loaded assemblies to find them. I'm not sure if this will make any noticeable difference, but it can't harm.
I still can't explain how this had been working up until now, and suddenly stopped, as I hadn't changed any references, nor the way I was doing the data access. Still, it seems to be working now, which is all that matters.
Hope this helps someone.

AttachFile locks attachment for deleting on Windows XP

I'd been working on a plugin when I discovered this. I can't say for sure if this behavior happened before or not on my machine (it doesn't on our test server, a Linux box), but after attaching a file, I can't delete it until the server restarts. I can't delete through the UI or by manually navigating to the server directory and trying to delete from there.
Has anyone ever encountered this before? Could it be something environmental on my box??
Most probably it's a permission issue in that folder, which allows your JIRA user (a user under which privileges JIRA instance runs) to create files, but not to delete them (or something even more fun) :) Try deleting the temp folder (where your uploaded attachments reside) and recreate it again, adding your JIRA web user to the access list for that folder.
The workaround to delete files, when some other process is holding a lock on the file, without having to terminate that process, is to use Unlocker. But be warned, when Unlocker unlocks a file it does that in a way which does not notify the lock holder that the file has been unlocked by force. That means that the lock holder still thinks it holds the lock on the open file which it doesn't (the file handle is invalid). That means that some applications might crash due to unexpected state of the supposedly open file. Btw, I've been using Unlocker since forever and it rarely caused any crashes, but it's better to be warned.

MVC3 Entity Connection string disappearing

I am having a very frustrating problem with my current project. It is continually losing the connection string binding for Entity models.
I have multiple models for different databases in separate areas and was having no problems. Suddenly now whenever I try to update from the database I get the connection string setup prompt. I select for it to add it to the Web.config with the password but it doesn't ever pick it up there again. They all are still in the web config but it just doesn't see them.
If I remove all the connection strings from the config file it will write the new one there. Then when I try to set up a Stored procedure/Function Import, I still get the statement in the lower box:
No database connection has been configured for this model.
I have tried rebuilding the project and creating the models again from scratch and that works for a while. When I try and bring the project in under Perforce source control, it winds up getting re-corrupted & the connection string goes away. It affects all of my models too.
I am also using EF 4.x DbContext Generator to create context files. They work fine. I am also able to run the application and it connects to the database just fine and returns data. No issues there. I am just unable to update Entity Complex types from the DB or import any more stored procedures.
An even weirder occurrence was that I opened a broken project from a different directory then opened an uncorrupted copy it instantly became broken also. Contagious!
Any thoughts on where to look into to see why this is happening? Has anyone else had this issue?
I seem to have found where the issue is coming from.
I seem to have a bad value somewhere in my web.config which causes the issue. Here is the work around I found did the trick and showed it's the config:
When the binding breaks, I closed the project then swapped out the web.config with one from a good build which was missing a couple keys but worked well enough to bind.
I reopen the the solution and the "No database connection..." error goes away.
Then while the solution is still open I re-swap the web.config back in and it still works.
This is far from optimal but I can work until I figure out the bad value via doing some compares.
I will comment on this again once I determine the exact issue.

Why am I getting the message "The specified request cannot be executed from current Application Pool"?

Quite not sure why I see this error.
I navigate to my Login View like so http://test.staging.com/mywebsite/Login
My Login view was just redone using MVC but I have seen this same error message going to an aspx page as well...
If I use http I get the error message The specified request cannot be executed from current Application Pool.
If I use https://test.staging.com/mywebsite/Login, I'm good.
If I don't specify a protocol, test.staging.com/mywebsite/Login, I get the error as well
Is there an error happening under the covers and my custom error page can't be shown like discussed here?
What are some other causes of this error?
That usually means your custom errors are configured to run as a different AppPool.
You can read more at MSDN. (See section "Using Custom Errors from Another Application Pool").
There are two ways to correct this behavior. The first is possibly not one that you are interested in because it would require you to change your current architecture and run both sites in the same application pool (such as share the same worker process memory space). To do this, simply move the /errors virtual directory to run in the same application pool as the site for which it serves the custom error.
The second way is to make use of a registry key provided by IIS 6.0. This registry key makes sure IIS 6.0 does not check the metadata during the execution of the custom error and therefore allowing this to work.
See the article for information on the registry key fix.
It may also mean that you are using something along the lines of Server.Transfer to a page that is in a different AppPool.
It could be because you're using different versions of ASP.NET for one or many apps in the pool.
Make sure all apps in the pool use the same version of ASP (e.g. ASP 2.0.50727)
If you just added a new app, try changing the app momentarily to a different version of ASP, then back to same version. I experienced an issue where the displayed version was correct, but under the hood, a different version was used!
Check your event log, under Application, to get more details about the error.
The message would be caused by your page server-side redirecting to a page served by another application pool. Such as for example, in your link, the error page.
I know this is an old thread, but I stumbled upon it and found a different solution. Here's what worked for me: Make sure your application handles .asmx files correctly
From IIS:
Right Click on your project > Properties > Configuration
If necessary, add the .asmx file extension that maps to the aspnet_isapi.dll
Limit to: "GET,HEAD,POST,DEBUG" and restart.
Because I can't comment on vcsjones's answer, I'll add it down here. The DWORD value IgnoreAppPoolForCustomErrors needs to be set under HKLM\SYSTEM\CurrentControlSet\Services\W3SVC\ Parameters vs HKLM\SYSTEM\CurrentControlSet\Services\W3SVC referenced in that technet article. Set it to 1 and do an iisreset and you're good to go.
Source Blog Post
In my particular case, I received this error while trying to serve a content (non ASP.NET) website while it was an Application. Right-Clicking the virtual folder and removing the application fixed it for me.
In my case the application used the application pool that didn't exist. I have no idea how it's happened.

Starting a windows service fails with error 1053

I have a windows service that is failing to start, giving an error "Error 1053: The service did not respond to the start or control request in a timely fashion".
Running the service in my debugger works fine, and if I double click on the the service .exe on the remote machine a console window pops up and continues to run without problem - I can even see log messages showing me that the program is processing everything the way it should be.
The service had been running fine previously, though this is my first time, personally, trying to deploy it with the most recent changes made to the program. I've evaluated those changes and cant figure out how they might cause this problem, particuarly since everything runs fine when not started as a service.
The StartRoutine() method of the service impelmentation is empty, so should be returning in a "timely fashion".
I've checked the event logs on the computer, and it doesn't give any additional information other than it didn't hear back from the service in the 30 second requisite time frame.
Since it works on my machine, and as a double-clicked executable, how would I go about figuring out why it fails as a service?
Oh, and it's .NET 2.0, so it shouldn't be affected by the 1.1 framework bug that exhibited this symptom (http://support.microsoft.com/kb/839174)
The box is a windows server 2003 R2 machine running SP2.
This is a misleading error. It's probably an unhandled exception.
Empty your OnStart() handler then try this in your constructor...
public MainService()
{
InitializeComponent();
try
{
// All your initialization code goes here.
// For instance, my exception was caused by the lack of registry permissions
;
}
catch (Exception ex)
{
EventLog.WriteEntry("Application", ex.ToString(), EventLogEntryType.Error);
}
}
Now check the EventLog on your system for your Application Error.
Could be a number of things and it might help to get a stack trace on the machine exhibiting the problem. There are a number of ways to do this but the point is that you have to see where this is failing in the code.
You can do this with remote debugging, but a simple thing might be to just log to the event logger, or file log if you have that. Literally, putting "WriteLine("At class::function()") throughout portions of the code to see if you've made it there.
This will at least get you looking in the right direction (which ultimately is the code).
Update:
See Microsoft's How to Debug Windows Services article for details in troubleshooting startup problems using WinDbg.
This related question details nice ways to debug services that are written in .NET.
I agree with Scott, the easiest way to find out what's happening is to put some traces in the start-up code (maybe it doesn't even come to your start-up code).
If this doesn't help, you can post your code here so others can take a look.
perhaps lacking some dependence, try this :
- deregister your service
- register again
If fail at register means that lack an module.
If the StartRoutine is empty, you are probably starting it somewhere else.
IIRC you need to fire off a worker thread, and then return from StartRoutine.
One of the problems which may lead to this error is if windows service which needs to be deployed consists of some error i.e it may be simple authorization error or anything as in my case I have referenced some folders and files for logging which were not existing, but when provided the right path of those file and folders it solved my problem.
I ran through every post on this particular subject and none of the responses solved the problem, so I'm adding this response in case this helps someone else. Admittedly this only applies to a new service, not this specific case.
I was writing a File listening service. As a console app, it worked perfectly. When I ran it as a service, I got the same error as above. What I didn't know (and many of the MSDN articles about services conveniently leave out) is that you need to have your class executed from within ServiceBase.Run( YourClassName());. Otherwise, your app executes and immediately terminates and because it terminated, you get the error above even if no error or exception occurred. Here is a link to an article about this. It actually discusses setting up your app for dual use - Console app and service: Create a combo command line / Windows service app
I had that issue and the source of my problem was config file. I edited it in notepad and notepad added one special character which cause service not to run properly because config file was ruined. I saw that special character in notepadd++ and after delete it, service started to run successfully as previous did.
In my case, the correct .NET framework was not installed on the server that I was installing the Windows service on.
One other reason is If you copy the DLL in 'debug' mode to installation folder this issue will come.What you need to do is Run the project in 'Release' mode copy the DLL or directly form Release folder rather than Debug folder,,and copy that DLL in to installation folder,it will work.You can see the reduction in size of DLL ,it will not contain any debug symbols and like that
