ASP.NET vNext - MissingMethodException：找不到方法：Microsoft.CodeAnalysis.Diagnostic> EmitResult.get_Diagnostics（）'

Question

I upgraded this morning to VS2015 RC, and I created a new project using the ASP.NET 5 Template - Web Site. I have an error that I am not able to solve:

An unhandled exception occurred while processing the request.

MissingMethodException: Method not found: 'System .Collections.Immutable.ImmutableArray`1 Microsoft.CodeAnalysis.Emit.EmitResult.get_Diagnostics()'.

Microsoft.AspNet.Mvc.Razor.RoslynCompilationService.Compile(RelativeFileInfo fileInfo, String compilationContent)

Here is the full error stack:

When I run a dnvm list command:

       1.0.0-beta4          clr     x86          <mypath>\.dnx\packages
       1.0.0-beta4          coreclr x64          <mypath>\.dnx\packages
       1.0.0-beta4          coreclr x86          <mypath>\.dnx\packages
       1.0.0-beta5-11596    clr     x86          <mypath>\.dnx\packages 
  *    1.0.0-beta5-11624    clr     x86          <mypath>\.dnx\packages       default

I tried to use as well the 1.0.0-beta5-11596 and the 1.0.0-beta4 clr but I get the same result.

Any idea?

Thanks.

Answer 1

I think David is right, I had the same issue and I was able to resolve it by:

• Opening the %USERPROFILE%\\.dnx directory
• Deleting everything from the packages directory
• Deleting the beta5 directories from the runtimes directory
• Changing the value of the defaults.txt in the alias dir to point to one of the beta4 runtimes

Once I did that I opened the project back up, the packages restored successfully and I was able to run the application. For whatever reason the defaults.txt was pointed at the beta5 runtime for whatever reason, assuming this was set sometime when playing around with the command line tooling.

Hope that works for you too!
