I know that C++ projects are not supported at all, but the C++ project builds fine. The code processing it just somehow messes up something. For debugging purposes, I've minimized the repro solution (which fails 100% on my machine to analyze the C# project), but am unsure where to upload it. The exception itself is this: Quote: NCrunch: If you are experiencing problems in getting this project to build, have a look at https://www.ncrunch.net/...ing_project-build-issues NCrunch has encountered an internal error: System.Exception: nCrunch.Compiler.StaticManipulation.CilTypeHashException: Unable to hash type 'Repro.Class1' due to exception: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. at nCrunch.Compiler.Cil.Symbols.Legacy.CilLegacySymbolsDataSource..ctor(Byte[] pdbFileContent, UInt32 entryPointToken) at nCrunch.Compiler.Cil.CilAssembly.Load(FilePath assemblyFile, CilContext context) at nCrunch.Compiler.Cil.CachedCilAssembly..ctor(FilePath assemblyFilePath, CilContext context, Boolean isInstrumentationTarget) at nCrunch.Compiler.Cil.CilContext.LoadAssembly(FilePath assemblyFilePath) at nCrunch.Compiler.Cil.CilSession.LoadAssembly(FilePath assemblyFilePath, Boolean isInstrumentationTarget) at nCrunch.Compiler.Cil.CilSession.(String , String , UInt16 , UInt16 , UInt16 , UInt16 , String , String ) at nCrunch.Compiler.Cil.CilSession.LoadAssembly(CilAssemblyReference assemblyReference) at nCrunch.Compiler.Cil.CilSession.GetReferencedModule(CilModule referencingModule, UInt32 assemblyRefTableRowIndex) at nCrunch.Compiler.Cil.AssemblyIdentity.CilAssemblyRefTable.GetAssemblyModuleByRowIndex(UInt32 tableIndex) at nCrunch.Compiler.Cil.Types.CilTypeReference.(CilModule ) at nCrunch.Compiler.Cil.Types.CilTypeSignature.GetUnderlyingTypeForEnum() at nCrunch.Compiler.Cil.CustomAttributes.CilAttributeArgument.get_SizeInBytes() at nCrunch.Compiler.Cil.CustomAttributes.CilCustomAttributeValue.get_NamedArguments() at nCrunch.Compiler.StaticManipulation.CilMethodHashGenerator.HashCustomAttribute(FNV64& hash, CilCustomAttribute customAttribute) at nCrunch.Compiler.StaticManipulation.CilMethodHashGenerator.HashType(FNV64& hash, CilTypeDefinition type) at nCrunch.Compiler.StaticManipulation.BuiltCilAssembly.ExtractClassMethodData(TestFrameworkDescription[] applicableTestFrameworks, IDictionary`2 codeFileIDsByForegroundFilePath, Boolean storeImpactHashes) at nCrunch.Compiler.StaticManipulation.BuiltCilAssembly.ExtractClassMethodData(TestFrameworkDescription[] applicableTestFrameworks, IDictionary`2 codeFileIDsByForegroundFilePath, Boolean storeImpactHashes) at nCrunch.Compiler.CilProcessingTasks.CilMethodHashingTask..() at nCrunch.Common.PerformanceTracking.PerfTracker.TrackActivity(String name, Action activity) at nCrunch.Compiler.CilProcessingTasks.ConcurrentCilTaskProcessor.() at nCrunch.Compiler.CilProcessingTasks.ConcurrentCilTaskProcessor.ProcessTasks(Int32 backgroundThreadsAllowed) at nCrunch.Compiler.RemoteBuildRunner.(ComponentInstrumentationParameters , BuildOutput , IBackgroundTaskProcessor ) at nCrunch.Compiler.RemoteBuildRunner.PerformPostProcessingOfBuiltAssembly(ComponentInstrumentationParameters instrumentationParameters, BuildOutput output, IBackgroundTaskProcessor backgroundTaskProcessor) at nCrunch.Core.BuildManagement.BuildEnvironment..() at nCrunch.Common.PerformanceTracking.PerfTracker.TrackActivity(String name, Action activity) at nCrunch.Core.BuildManagement.BuildEnvironment.Build(SnapshotComponent snapshotComponentToBuild, IList`1 referencedComponents, GridClientId gridClientId, IList`1 customEnvironmentVariables, IPlatformBuildExtender extender, Guid taskId, GridClientDescription clientDescription, Boolean extractCoverageReportStructure) The C++ project in question contains nothing but a CLR enum with a single field and all the boilerplate. That enum is used in an attribute on the C# project. Best regards, Marian

This seems to be related to the structure of the PDB file. Could you submit your sample through the contact form? I'll take a look at this and see what I can do about getting it fixed. As a potential workaround, could you try changing your project to use portable PDBs in your build settings?

It seems that the instrumentor is trying to load this PDB, then falling over because it doesn't contain the same data that would be expected for a .NET assembly. There's a couple of options here. You can either compile the C++ project without a PDB in the output (so there's nothing to load), or you can try the fix in the build below: NCrunch_Console_4.20.0.1.msi NCrunch_Console_4.20.0.1.zip NCrunch_GridNodeServer_4.20.0.1.msi NCrunch_GridNodeServer_4.20.0.1.zip NCrunch_LicenseServer_4.20.0.1.zip NCrunch_VS2010_4.20.0.1.msi NCrunch_VS2010_4.20.0.1.zip NCrunch_VS2012_4.20.0.1.msi NCrunch_VS2012_4.20.0.1.zip NCrunch_VS2013_4.20.0.1.msi NCrunch_VS2013_4.20.0.1.zip NCrunch_VS2015_4.20.0.1.msi NCrunch_VS2015_4.20.0.1.msi.7z NCrunch_VS2015_4.20.0.1.zip NCrunch_VS2017_4.20.0.1.msi NCrunch_VS2017_4.20.0.1.msi.7z NCrunch_VS2017_4.20.0.1.zip NCrunch_VS2019_4.20.0.1.msi NCrunch_VS2019_4.20.0.1.msi.7z NCrunch_VS2019_4.20.0.1.zip NCrunch_VS2022_4.20.0.1.msi NCrunch_VS2022_4.20.0.1.msi.7z NCrunch_VS2022_4.20.0.1.zip
