Internal.TypeSystem.TypeSystemException+TypeLoadException: [TEMPORARY EXCEPTION MESSAGE]

[ghost]

I am trying to create a single executable file targeting x86 windows, from a .net core 2.0 project. The command that I execute on x86 Native Tools Command Prompt for VS 2017 is :

dotnet publish DataSoft.ServiceIntegration.csproj -c Release -r win7-86 --output native /p:IlcPath=c:\work\CoreRT\bin\Windows_NT.x64.Release

Here is the output I get :

I have tried every solution I have found online with no luck so far. Can someone please point me in the right direction ?

Thanks in advance.

System.Reflection.Emit.AssemblyBuilder

CoreRT does not support Reflection.Emit (#5011). Also, it works on x64 only; no x86 yet (#4589).

I didn't know about Reflection.Emit, and I thought x86 was supported from #4598

Nevertheless, thank you for your response.
