What causes ModuleLoadException in RoleEnvironment initializer?

Question

I'm debugging a class library with the WCF service, which uses installed Azure SDK 2.4 on Windows 8.1 using WCF Test Client and Visual Studio 2013 Ultimate debugger. The library was compiled using AnyCPU. An exception occurs when RoleEnvironment.IsAvailable is called. Here are the details:

  Message=The type initializer for 'Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment'   threw an exception.
  ...
  InnerException: System.TypeInitializationException
       Message=The type initializer for '<Module>' threw an exception.

                      at <CrtImplementationDetails>.LanguageSupport.Initialize(LanguageSupport* )

Enabling of unmanaged code debugging gave me no new information. I tried to install the last version of Azure SDK, adding useLegacyV2RuntimeActivationPolicy="true" flag to config file, but none of this helped. The same library code invoked from my test project works without exceptions. Using both x86 and x64 test settings. Debug folders seem to contain the exact same version of ServiceRuntime dll.

What caused this exception, and how I can fix it?

Have you ever found a solution to this problem? Having this problem on our project with TeamCity and the NUnit testrunner. The MSTest runners all work properly. — Jan_V, Jun 30 '15 at 14:30
I am getting the same error, however when accessing RoleEnvironment in a normal Azure app service - could not find any solution yet - this is driving me crazy... — olee, Nov 17 '17 at 14:39

I found a workaround to an issue I had similar to yours (identical to the MS Connect bug)

Win10, VS2015. Using Fusion Log Viewer I found my VS test runner is te.processhost.managed.exe. Following similar instructions found here, I added the following to C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\TE.processHost.managed.exe.config

<startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>

Restarted Visual Studio and the tests started working.

It looks like a new bug related to the app domains. I saw it when accessing RoleEnvironment from MSTest, which uses app domains to isolate the tests. Here's the stack trace:

MS Connect is down right now (maybe it's trying to use `RoleEnvironment` with app domains :). Otherwise, I'd submit a bug. — Edward Brey, Aug 01 '15 at 21:58
The site is back up (super putzy though - maybe lots of people reporting bugs). [Here's the bug report](https://connect.microsoft.com/VisualStudio/feedback/details/1617665) — Edward Brey, Aug 02 '15 at 00:58

For anyone else having this issue when trying execute a Test task in Visual Studio Team Services (VSTS), include a custom settings file in your build and set the path location on the task definition. Make and set the ForcedLegacyMode attribute = true. This solved the issue for me.

<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
      <TargetFrameworkVersion>Framework45</TargetFrameworkVersion>  
  <MSTest>
     <ForcedLegacyMode>true</ForcedLegacyMode> 
  </MSTest>
</RunSettings>

For documentation on other settings and properties for Visual Studio Test files see https://msdn.microsoft.com/library/jj635153.aspx?f=255&MSPPError=-2147217396.

See the VSTS Task documentation for the Test Task here enter link description here
