PDB0009 Invalid type name

[jnm2]

When converting Windows PDBs to portable PDBs, I'm getting this diagnostic:

PDB0009: token 0x06000DDC: Invalid type name specified in StateMachineTypeName custom debug information: <System.Collections.Generic.IEnumerable<DevExpress.Charts.Native.IAxisData>.GetEnumerator>d__0

How should I address this issue?

What version of the compiler is this compiled with?

What version of the compiler is this compiled with?

The PDB and DLL? I don't know if I can find out since I didn't build them. Is that information embedded in one of the files? The csproj from the sources contains ProductVersion 9.0.30729 and

  <PropertyGroup Condition=" '$(VisualStudioVersion)' != '' And $(VisualStudioVersion) &gt; 10.0 ">
    <LangVersion>4</LangVersion>
  </PropertyGroup>

But only a lower bound could be inferred from that, I guess.

👍 Is there a way I could have figured this out by looking at docs?

If these binaries were built by an old compiler (pre-Roslyn, that is before VS 2015) it is possible that some of the metadata and debug information is bad. The old compiler had a bunch of bugs. I can take a look if you can share the binary and the PDB with me.

Re errors: Most of the conversion errors are recoverable. If the converter produces PDB then you're good. The converter skips bad data and continues converting.

If you have time and want to look, let me know where you want me to send it. If you're confident that I'm not losing anything important, don't let me waste your time. 😃

My basic goal is to achieve source-stepping while incurring as little coupling as possible to Microsoft PDB format details at a certain point in time. If this conversion is not lossy in any way which could affect source stepping and debug evaluation, maybe I'll stick with this over Windows PDB rewriting. seealso

Ran into a couple of these, too:

PDB0016: token 0x0600782E: Invalid scope IL offset range: [32, 66)
