PostSharp not building on TeamCity: Cannot find assembly mscorlib

问题

PostSharp will build on local dev machine, it will not build on the TeamCity server, the error is:

unknown error PS0264: Cannot find assembly 'mscorlib, version=2.0.5.0, culture=neutral, publickeytoken=7cec85d7bea7798e'.

Here is an excerpt from the build log:

Update

After comparing file (local vs build server) in C:\ProgramData\PostSharp\InstalledFrameworks, I can see that my local machine has these additional frameworks:

  <Framework Identifier=".NETFramework" Version="4.7.1">
    <ReferenceAssemblies>
      <Directory Location="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.7.1\" />
    </ReferenceAssemblies>
  </Framework>
  <Framework Identifier=".NETPortable" Version="4.0">
    <ReferenceAssemblies>
      <Directory Location="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable\v4.0\" />
    </ReferenceAssemblies>
  </Framework>
  <Framework Identifier=".NETPortable" Version="4.5">
    <ReferenceAssemblies>
      <Directory Location="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable\v4.5\" />
    </ReferenceAssemblies>
  </Framework>
  <Framework Identifier=".NETPortable" Version="4.6">
    <ReferenceAssemblies>
      <Directory Location="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable\v4.6\" />
    </ReferenceAssemblies>
  </Framework>
  <Framework Identifier=".NETPortable" Version="5.0">

      <Directory Location="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable\v5.0\" />
    </ReferenceAssemblies>
  </Framework>

回答1:

The build server required Microsoft .NET Portable Library Reference Assemblies 4.6:

Download & install Microsoft .NET Portable Library Reference Assemblies 4.6
Extract C:\Program Files (x86)\Microsoft .NET Portable Library Reference Assemblies 4.6\PortableReferenceAssemblies.zip to C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETPortable\

Note: Character casing of the folder ".NETPortable" must be as defined. Use mkdir to create folders starting with a period symbol.

回答2:

Copying C:\ProgramData\PostSharp\BindingMaps from my local machine to the build server worked for me (Postsharp 4.2.19)
