I've just refreshed an app written in .net 2.1 to .net 6.0. I worked through the errors and the site appears to compile cleanly. After I published to the server had many errors. Working through them, and standing up a full IIS install on my own machine, I now have it down to a 404 error.
When running the exe straight from the console it runs without errors.

Looking through Event Viewer, there's nothing of note. System nothing for IIS, IIS-Configuration and IIS-Admin are empty.
Edit 2021-11-22
It took a morning, but I have Request Tracing installed. For those on windows 10, just go to Add Features > IIS > Health > Tracing. Don't believe the server 2012 pages. Below is a screenshot:
The actual xml and xslt were quite verbose.
I have reinstalled the Hosting package as administrator, just in case. The version installed was dotnet-hosting-6.0.0-win.exe. That didn't fix it. IIS was stopped/started at server level as well.
At the moment it looks like the handlerv2 is missing?
If any other logs or config are required please let me know
"At the moment it looks like the handlerv2 is missing?" is incorrect.
The correct interpretation of the FRT log is that ASP.NET Core module (handler configured in your web.config) runs fine, and decides that no routing rule yields a result for the incoming URL http://localhost/ReportGroups. Thus, it returns 404 as designed.
It is your responsibility to review IIS configuration (site/app) as well as your source code on routing to see what should be the right URL to use to access the target pages. And unless you share those parts, discussion on this question cannot move forward.
I am trying to wire up Azure Key Vault in my ASP.NET (.Net Framework) MVC Web App using Visual Studio 2017 Community 15.7.5 Connected Service targeting .Net 4.7.2.
It adds a configBuilder with the name AzureKeyVault with an attribute called vaultName that throws a "The 'vaultName' attribute is not allowed." warning.
When I run the application I get an error that the configBuilders attribute on the appsetting tag is not good like so:
I am using the following package versions which are all current:
<package id="Microsoft.Azure.KeyVault" version="3.0.0" targetFramework="net472" />
<package id="Microsoft.Azure.KeyVault.WebKey" version="3.0.0" targetFramework="net472" />
<package id="Microsoft.Azure.Services.AppAuthentication" version="1.0.3" targetFramework="net472" />
There is an update to Microsoft.Azure.Services.AppAuthentication but it is a preview and it caused dependency issues with other packages.
tldr; - you probably don't have the appropriate permissions to access the key vault.
In currently released versions of the .Net framework, detailed errors about config builders are not always easily discoverable in the ASP.NET yellow screen. We have changes in vNext to address this issue, but it is currently a problem for 4.7.1/2. For the time being, if you create a simple console app to read appSettings with the same config builder configuration, you should see more exception information in the stack that gets spit out.
Based on the yellow screen you posted though I would guess (and its really just an educated guess based on past reports and nothing specific in your case) you are running into an authentication issue in the Microsoft.Azure.Services.AppAuthentication library. When running in Visual Studio, that library can use your personal credentials to access the key vault. If deployed in Azure, they use a different magic technology to authenticate the application to the key vault. If you want to eliminate the "magic" and take more control over this, you can specify more detailed connection information with the 'connectionString' attribute. There is more information as well as a link to connection string details on our GitHub page (MicrosoftConfigurationBuilders).
As for the "The 'vaultName' attribute is not allowed." warning... it's just a warning. The .xsd that VS uses to validate configuration was not correctly updated to allow random attributes on configBuilder definitions. We hope to address this in a future VS release around the time that the next framework ships.
Steve Molloy was correct in that the Configuration Error was a red herring. I created a console app and the error messages were much better but they still required some investigation. Here's my Console App Code and packages:
static void Main(string[] args)
{
var azureServiceTokenProvider = new AzureServiceTokenProvider
(azureAdInstance:"https://InsertAADSubscriptionName.onmicrosoft.com/");
var keyVaultClient = new KeyVaultClient(
new KeyVaultClient.AuthenticationCallback(azureServiceTokenProvider.KeyVaultTokenCallback));
var secret = keyVaultClient.GetSecretAsync(
"https://InsertKeyVaultName.vault.azure.net", "InsertSecretYouWantBack").GetAwaiter().GetResult();
}
<packages>
<package id="Microsoft.Azure.KeyVault" version="3.0.0" targetFramework="net472" />
<package id="Microsoft.Azure.KeyVault.WebKey" version="3.0.0" targetFramework="net472" />
<package id="Microsoft.Azure.Services.AppAuthentication" version="1.0.3" targetFramework="net472" />

I put a breakpoint on the last bracket and kept looking for my secret value in the variable secret. I kept getting the following error indicating that Azure AD wasn't able to authenticate my local environment and return an access token.

The problem was that since I was running the app locally I needed to be logged in to Azure CLI locally. To do this: first install Azure CLI on your machine, then go to a CMD or a PowerShell prompt and type az login and follow the instructions returned.
This did the trick; the console app was able to get an access token.
I tried it on my web app in the original question above and it worked as expected.
I have MVC 3 Application that used to work fine on osFamily 1 (Win 2008 SP2) and .Net 4.0 and would like to upgrade to .Net 4.5 and Windows 2012.
My project is upgraded to .Net 4.5 and it builds without any problems and runs in emulator with no problems.
When I deploy to Windows Azure the role i get this message -
"Recycling (Waiting for role to start... Sites were deployed. [2013-06-01T10:43:59Z])"
I remotely logged in to the machine and I found the below error messages in the windows event viewer.

I did try to remove the Windows.Azure.Caching from my project by removing the package from NuGet, them I tried to deploy to cloud and the web role was deployed successfully but I was unable to browse to my application as it was complaining about in the web.config.
I found the below code was still there in web.config and not cleaned by nuGet.
<dataCacheClients>
<dataCacheClient>
<autoDiscover isEnabled="true" identifier="OpenSpaceGUI" />
</dataCacheClient>
</dataCacheClients>
I removed the above code from web.config and deployed to cloud once again but no luck the web role is recycling in a end-less loop and i found this error details once I remote logged in to the server.

You need to run your application in OS family 3 if you want .NET 4.5 support. You need to specify this in your ServiceConfiguration.Cloud.cscfg file
<ServiceConfiguration serviceName="XXX"
xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration"
osFamily="3"
osVersion="*"
schemaVersion="2012-10.1.8">
It may not be possible to upgrade your instance and you may have to deploy a new one.
More details on the Azure blog
Update
WaHostBootstrapper.exe will fail when there is something wrong with your azure service (most often without any helpful details) so it is hard to determine exactly what is wrong. It could be something as simple as missing references.
From what you have posted it looks like some of your Microsoft.WindowsAzure.Plugins are having a hard time as well. I would try to remove them and see if the role still fails.
Side note - it is no longer necessary to specify Remote Access in your cscfg file. From ScottGu's blog :
Windows Azure Cloud Services support the ability for developers to RDP into web and
worker role instances. This can be useful when debugging issues.
Prior to today’s release, developers had to explicitly enable RDP support during
development – prior to deploying the Cloud Service to production. If you forgot to
enable this, and then ran into an issue in production, you couldn’t RDP into it
without doing an app update and redeploy (and then waiting to hit the issue again).
With today’s release we have added support to enable administrators to dynamically
configure remote desktop support – even when it was not enabled during the initial
app deployment. This ensures you can always debug issues in production and never
have to redeploy an app in order to RDP into it.
If you can establish a remote desktop connection with the machine, then do that and, rather than just looking in the Event Viewer, open up IIS Manager and browse to your website.
For me, this will often show an ASP.NET yellow screen error identifying any required files that have not been included within your deployed Azure package. You should mark those files as "Copy Local=true" and redeploy - you may need to do this a number of times to catch all of the missing files.
I have a web-site named CCESD set up in IIS7; my application root folder is D:\Websites\CCESD\CCESD. I also have a folder holding third-party assemblies (not all of which are strong-named) at D:\Websites\CCESD\CCESD\BinCommon: this is because I also have many other web applications under this root site in IIS that will share the DLLs, some of which are unmanaged code and so can't go in the GAC. My web.config file looks like this:
<compilation defaultLanguage="c#" debug="true" targetFramework="4.0">

<add assembly="Telerik.Web.UI, Version=2012.1.288.40, Culture=neutral, PublicKeyToken=121FAE78165BA3D4" />

I have checked that the file exists and the version and public-key information are correct. What am I doing wrong?
I found it eventually; in the end, it was down to this:
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
My project began life in Visual Studio 2005; hence the xmlns attribute shown above was present in the containing element of my web.config file. Removing it fixed the problem and now my assemblies are being loaded correctly.
Googling reveals that the xmlns attribute is there to enable intellisense in Visual Studio (which indeed it does): it says nothing about having any effect on loading assemblies, so this is all a little strange (not to mention annoying). Still, now it's working.
something weird is happening! is a couple of days that my users are experincing a "logging out" isses, the error message is:
Event code: 4005
Event message: Forms authentication failed for the request. Reason: The ticket supplied was invalid.
Here the data:
the website is running on 3 server behind a load balancer
yes, machine key is the same all across thw websites, because the configuration is shared and all servers are pointing to the same folder on a NAS, this is the key:
<machineKey decryption="AES" decryptionKey=" ... snipped for security reasons ... "
validation="SHA1" validationKey=" ... snipped for security reasons ..." />
I created the keys using an console app as suggested here: http://msdn.microsoft.com/en-us/library/ff649308.aspx#paght000007_webfarmdeploymentconsiderations
the form auth config is
<authentication mode="Forms">
<forms loginUrl="SignIn.aspx" timeout="525960" />
</authentication>
the time on the servers is in sync
... Any other suggestions?
Cheers
Make sure that this patch is installed on every server in the farm.
(It changes ticket handling; installing it on some of the servers will cause issues)
