Hi,

I'm converting another of my projects over to the new world of improved csproj + netstandard, and am seeing this error with NCrunch 3.7.0.4:

System.TypeInitializationException: The type initializer for 'KBCsv.CsvReader' threw an exception.
at KBCsv.CsvReader.FromCsvString(String csv)
at KBCsv.UnitTests.CsvReaderFixture.header_record_defaults_to_null() in C:\Users\Kent\Repository\KBCsv\Src\KBCsv.UnitTests\CsvReaderFixture.cs:line 187
System.IO.FileLoadException: Could not load file or assembly 'nCrunch.TestRuntime.DotNetCore, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. A strongly-named assembly is required. (Exception from HRESULT: 0x80131044)
at KBCsv.CsvReader..cctor()

If I disable signing of my assemblies then I get a different error:

System.TypeInitializationException: The type initializer for 'KBCsv.CsvReader' threw an exception.
at KBCsv.CsvReader.FromCsvString(String csv)
at KBCsv.UnitTests.CsvReaderFixture.header_record_cannot_be_set_if_passed_first_record() in C:\Users\Kent\Repository\KBCsv\Src\KBCsv.UnitTests\CsvReaderFixture.cs:line 224
System.MethodAccessException: Attempt by security transparent method 'KBCsv.CsvReader..cctor()' to access security critical method 'nCrunch.TestRuntime.TestCoverageEventListener.NCrunchExitMethod(Int32, Int32 ByRef, UInt32)' failed.
at KBCsv.CsvReader..cctor() in C:\Users\Kent\Repository\KBCsv\Src\KBCsv\CsvReader.cs:line 95

If I disable security transparency on my assemblies, then my tests execute fine.

How can I get my tests to run regardless of signing/security transparency?

Thanks

Thanks for sharing this issue.

When NCrunch instruments your code, it adds a reference to nCrunch.TestRuntime.DotNetCore. This is not a signed assembly, which usually isn't a problem for .NET projects.

How has this project been configured? Is there any chance you can share its XML with me?

Sure thing. But can you clarify exactly what you want me to share? The csproj for the assembly under test? For the unit test project?

Thanks

It looks like this is coming from the csproj under test, assuming that this is the assembly containing the CsvReader class. If you could share the contents of the .csproj, that would be extremely helpful.

Yep - here you go:

    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
    <SignAssembly>True</SignAssembly>
    <AssemblyOriginatorKeyFile>..\KBCsv.snk</AssemblyOriginatorKeyFile>
  </PropertyGroup>

  <ItemGroup>
    <None Remove="Properties\ExceptionHelper.xml" />
  </ItemGroup>

  <ItemGroup>
    <Compile Include="..\AssemblyInfoCommon.cs" Link="Properties\AssemblyInfoCommon.cs" />
    <Compile Include="..\AssemblyInfoCommonSecurity.cs" Link="Properties\AssemblyInfoCommonSecurity.cs" />
  </ItemGroup>

  <ItemGroup>
    <EmbeddedResource Include="Properties\ExceptionHelper.xml" />
  </ItemGroup>
</Project>


PS. Is it just me, or are the BBCode icons for Code and Quote the wrong way around?

Thanks for sharing this. I haven't yet managed to reproduce the security issue, but I assume that this is tied to the nCrunch.TestRuntime.DotNetCore assembly not being signed. It appears that this assembly really should be signed in the same way as its sibling (nCrunch.TestRuntime.dll).

I've see about getting this included in the next release. For the time being, I recommend keeping the signing of your assemblies and security transparency disabled when running under NCrunch. It should be possible to do this using the #!NCRUNCH compiler directive around the attributes you're using to declare your security.
