I am binding a 3rd party JAR file for my Xamarin Android project. It binds with no errors but quite a few warnings about "hiding" (CS0108) and "not hiding" (CS0109) accessible members.
When I code in the Android project, the classes I expect aren't there but corresponding interfaces are. This is making the use of this library difficult, as I reference their help system and samples.
Can anyone answer as to why this occurs, interfaces en lieu of classes? Can I use the MetaData.xml file to prevent this? If so, it would be great to have an example, as I find the various entries none too intuitive.
The JAR is bound as an Embedded JAR. I have used both "Android Class Parsers" and "Codegen Targets" in all permutations possible in VS2017. It is being compiled for the same "Target Framework" as the Android Project.
This JAR is for UltraLite db accessing.
I continued to debug this issue and I decompiled the JAR. Result is that all the objects I was expecting as a Class are defined in the JAR file as an interface. SAP UltraLite support let me down on this one. But then they said this JAR is intended for and works in Android Studio. It has not been vetted for Xamarin.

I've just written the first version of a workflow activity that will run Resharper's Code Issues on the projects and parse the output to display the issues as build warnings and errors.
At first, I was going to just call Resharper's command line and parse the resulting xml manually. After fiddling with the dlls in Resharper's SDK (through disassembly mostly), I found a way to parse the results using it's own public classes, which I figured was a much more elegant and safe way to do this.
The first problem I have is that that nuget package is absolutely huge. There is 140mb of files in there, which to me is absurd for a single, unpartitioned package. There seems to be such heavy coupling between them that by using just a few model classes and the parser class, I have to drag a dozen or so of those dlls along, some of them which seemingly have nothing to do with the main dlls I need. This is not a show stopper though, I'm struggling with something else now:
In the end, I managed to track down the dependencies I needed to 41 assemblies (which is, again, insane, but alas). Initially, I tried removing everything and adding the missing references one by one, but this turned out to be unreliable, still missing some indirect references, even after compiling successfully. Then, I decided to code a small console application to find all referenced assemblies in the main Resharper assemblies I used, which gave me the 41 references I mentioned. This is the code I used to find every dependency.
Since these are custom activities we are talking about, I decided to create a unit test project to validate them. Using these 41 references only, everything works correctly.
When I added the activity to the build workflow though, and pointed the build controller to the source control folder containing the required assemblies, every time I schedule a build, the process fails stating that I need one extra dll from Resharper's SDK. For example, this is the first one it asks:
Could not load file or assembly 'AsyncBridge.Net35, PublicKeyToken=b3b1c0202c0d6a87' or one of its dependencies. The system cannot find the file specified. (type FileNotFoundException)
When I add this specific assembly to the TFS folder, I get another similar error for another dll, and this keeps going on and on.
What I wanted to know is how can I know exactly which assemblies a workflow XAML will need in order to run correctly? My custom activity dll has two specific CodeActivities and a XAML only activity that uses these two. This XAML acticity is what I'm directly using in the modified workflow template.
I see that besides the references in my project, the XAML activity also contains a TextExpression.ReferencesForImplementation section, with some assembly names. I've run my dependency finder program on those dependencies too, and the results are the same 41 assemblies already at the TFS folder.
Meanwhile I'll go with having the whole SDK into the custom assemblies folder, but I would really like to avoid this in the future since it has such an enormous amount of unneeded and big dlls in there.
First, we have request for our command line tool to support workflow activity and we decided to implement just plain MsBuild task which is universal and works in TFS too. Task and targets files are included in ReSharper CLT 8.2.
Second, if you still want to implement workflow activity it's pretty easy to do with new API in CLT, designed specially for custom processing of found issues - http://confluence.jetbrains.com/display/NETCOM/Custom+InspectCode+Issue+Logger.
And last, but not least, you do not need to put in VCS binaries of ReSharper SDK package.
Use NuGet's restore package functionality.
If you have any other questions I'll be glad to answer them.
A custom activity is being load and run by .NET CLR like any other .NET program. If the stack trace reports a missing file, then it's required by the CLR and you can't change this fact without refactoring your code.
Having an entire SDK references in the custom assembly folder doesn't make sense. I would prefer GAC deployment over huge binaries folder in the source control. Or maybe consider having these activities running an pre\post build scripts in MSBuild or PowerShell.
I have used NB to add a "client web service" to a Codename one app through the NB interface. This works fine in the simulator.
The WSDL classes are generated during build automatically and I have them landing in com.myco.myapp.generated package.
Having checked the generated JAR the WSDL classes are there all ok.
But when I push this to the "build for Android" to codename1, run on the device I get
An Internal application error occurred : java.lang.NoClassDefFoundError: com.myco.myapp.generated.SimpleStockList_Service
But the class is definitely there in the JAR.
I am sure its something to do with the JAR and its manifest, but never really had to get behind the scenes with Ant and JARs and builds to know what to do.
As the classes are generated during ant build, I can not pack them up into a library. (tried that and get fail due to 2 instances of same class.)
Codename One doesn't support binary libraries at this time, you will need to integrate the source code into the build process. There are many complexities involved in supporting binary libraries in such a setup.
Thanking Shai for his help.
Ultimate answer is not to use WSDL as moving objects relies Serialization which is not included in the small Java package.
Due to this I created a custom servlet which codename1 ConnectionRequest can deal with via a standard HTTP request.
This is how I achieved it

Is there any migration analysers available for MonoTouch ?
I have seen one for Mono, but not for MonoTouch.
Short answer: No, there is none at the moment.
Long answer
The situation is a bit different from Mono. In general you test a complete and compiled (against a specific version of the framework) .NET application with MoMA, to get a report of what pieces are missing (or incomplete) in Mono that could affect the execution of your application on other platforms (e.g. OSX and Linux).
Testing a complete applications for MonoTouch would reports tons of issues - since the UI toolkit is totally different. E.g. anything about System.Windows.Forms, WPF... would always missing.
However if your assemblies are already split into (something like) an MVC design it would be possible to test some (the non-UI parts) of them against definitions based on the MonoTouch base class library.
Finally if someone has an immediate need (or looking for a nice project) MoMA is available as open source and the evaluation versions of MonoTouch contains all the assemblies needed to build the definitions files. A bit of extra filtering could make this into a very nice tool.
Alternative
You can see a list of the assemblies that are part of MonoTouch and some platform restrictions (compared to .NET) you should be aware.

Any way to use some Scala for iOS coding?
Would it be possible to use the Scala.NET implementation, and then MonoTouch to run Scala code on an iOS device?
I have not been able to find a page with binaries of Scala.NET that I can test, so the following are just general guidelines as to what you can do with MonoTouch and .NET languages.
MonoTouch can run any ECMA CIL that you feed to it. When you consider using a new language with Monotouch, there are two components that come into play:
Tooling for the IDE
Runtime for the language
The tooling for the IDE is the part responsible for starting the builds, providing intellisense and if you use Interface Builder, it creates a set of helper methods and properties to access the various outlets in your UI. As of today, we have only done the full implementation for C#. What this means for an arbitrary language is that you wont get the full integrated experience until someone does the work to integrate other languages.
This is not as bad as it sound, it just means that you need to give up on using XIB files from your language and you probably wont get syntax highlighting and intellisense. But if you are porting code from another language, you probably dont need it. This also means that you would probably have to build your assembly independently and just reference that from your C# project.
So you compile with FoobarCompiler your code into a .dll and then reference in your main C# project.
The language runtime component only matters for languages that generate calls into a set of supporting routines at runtime and those routines are not part of the base class libraries (BCL). C# makes a few of those calls, but they are part of the BCL.
If your compiler generates calls to a supporting runtime that is not part of the BCL, you need to rebuild your compiler runtime using the Mono Mobile Profile. This is required since most runtimes target a desktop edition of the BCL. There are many other API profiles available, like Silverlight, Mono Mobile, Compact Framework and Micro Framework.
Once you have your runtime compiled with our core assemblies, then you are done
If you had read the MonoTouch FAQ, you would have noticed that it currently supports only C# and no other CLR languages.
Binaries for the Scala.NET library and the compiler can be obtained via SVN, in the bin folder of the preview:
svn co http://lampsvn.epfl.ch/svn-repos/scala/scala-experimental/trunk/bootstrap
Bootstrapping has been an important step, and ongoing work will add support for missing features (CLR generics, etc). All that will be done.
For now we're testing Scala.NET on Microsoft implementations only, but we would like our compiler to be useful for as many profiles and runtime implementations as possible.

We have a client/server application which includes a Windows Service and a Winform client tool. I've managed to create a Wix project in Visual Studio (2010, using the wix 3.5 toolset). I'm using the "harvest" feature on the references instead of specifying every file, because there are many library projects involved.
Problems I'm trying to figure out:
How to include referenced DLLs? Some are in the GAC, some are in a relative path within the workspace. I assume I could list each file explicitly but it seems like there should be a way for Wix to autodetect them.
How to install the service while "harvest" is enabled. All the examples I've seen require adding an explicit element with KeyPath=true. However this doesn't work with the harvest=true setting.
I realize that the harvest functionality might be a convenience which is not feasible when there are more complex things going on. Should I give up on harvesting and just try to specify each file explicitly?
Most of the examples I've seen on Wix have been just snippets of xml files. Is there anywhere I can find complete real-world examples of installing services other non-trivial setup features?
Use WixEdit. http://wixedit.sourceforge.net/
It's very easy to import an entire folder using it.
