Exception:: Member *** is declared in another module and needs to be imported

Hi,
I try use Scalpel.Fody, but I get exception:
Error 1 Fody: An unhandled exception occurred: Exception: Member 'PcapngUtils.Pcap.SectionHeader' is declared in another module and needs to be imported StackTrace: at Mono.Cecil.MetadataBuilder.LookupToken(IMetadataTokenProvider provider) at Mono.Cecil.SignatureWriter.WriteTypeSignature(TypeReference type) at Mono.Cecil.MetadataBuilder.GetFieldSignature(FieldReference field) at Mono.Cecil.MetadataBuilder.AddField(FieldDefinition field) at Mono.Cecil.MetadataBuilder.AddFields(TypeDefinition type) at Mono.Cecil.MetadataBuilder.AddType(TypeDefinition type) at Mono.Cecil.MetadataBuilder.AddTypeDefs() at Mono.Cecil.MetadataBuilder.BuildTypes() at Mono.Cecil.MetadataBuilder.BuildModule() at Mono.Cecil.ModuleWriter.<BuildMetadata>b__0(MetadataBuilder builder, MetadataReader _) at Mono.Cecil.ModuleDefinition.Read[TItem,TRet](TItem item, Func 3 read) at Mono.Cecil.ModuleWriter.BuildMetadata(ModuleDefinition module, MetadataBuilder metadata) at Mono.Cecil.ModuleWriter.WriteModuleTo(ModuleDefinition module, Stream stream, WriterParameters parameters) at Mono.Cecil.ModuleDefinition.Write(Stream stream, WriterParameters parameters) at Mono.Cecil.ModuleDefinition.Write(String fileName, WriterParameters parameters) at InnerWeaver.WriteModule() in c:\ConsoleBuildAgent\work\ed448661dbb30d2e\FodyIsolated\ModuleWriter.cs:line 18 at InnerWeaver.Execute() in c:\ConsoleBuildAgent\work\ed448661dbb30d2e\FodyIsolated\InnerWeaver.cs:line 65 Source: Mono.Cecil TargetSite: Mono.Cecil.MetadataToken LookupToken(Mono.Cecil.IMetadataTokenProvider) ScalpelProblem

My project contain nUnit framework. Exception occured, when first class has atribute [TestFixture], and second class contains object of first class (as field).

1. First class
   [TestFixture]
   public sealed class SectionHeader
   {
   public UInt16 MajorVersion { get; set; }
   }
2. Secons class
   public sealed class PcapWriter
   {
   public SectionHeader header = null;
   }

Here is an example project that can reproduce the issue:

I checked the source code but had no idea how to fix it :/.

so that is expected. Scalpel removes all test releated types. So since SectionHeader is marked with [TestFixture] it is removed. But you have a non-test related type PcapWriter which uses SectionHeader. So when it tries to write the assembly back it is pointing out that it cant find SectionHeader.

Either also remove PcapWriter with a [Scalpel.RemoveAttribute] or remove [TestFixture] from SectionHeader.
