canGetCookieForPInvokeCalliSig not implemented

[mellinoe]

I was trying to compile this project with CoreRT: https://github.com/mellinoe/veldrid/tree/master/src/NeoDemo.

I added the latest Microsoft.DotNet.ILCompiler package and simply ran dotnet publish -r win-x64.

  ILCompiler.CodeGenerationFailedException: Code generation failed ---> System.NotImplementedException: canGetCookieForPInvokeCalliSig

Any plans to implement this functionality, or is it tracked anywhere else? I searched briefly but didn't find anything.

Thanks for reporting it! We don't track this anywhere because we didn't hit it yet. Seems like this is from a calli to a p/invoke. I'll have a look if we can do something easy there in the next couple of days.

Seems like this is from a calli to a p/invoke.

Yes, that's likely, and it's probably from this library. If that's the case, then a simpler repro could probably be created from that package alone.

[mellinoe]

Small update: I checked again and this is indeed caused by the above library. SharpDX hits the same issue since it also uses calli directly.

@MichalStrehovsky +1, can't use SharpDX due this :-\

[feliwir]

@MichalStrehovsky +1 we are hitting this issue aswell in our project. Would greatly appreciate a fix

[jkotas]

@mellinoe @Krakean @feliwir The CoreRT packages with the fix are available now. Please give it a try and please let us know if you run into other blocking issues for you project.

@jkotas I get a lot further now, and most of my code works. I still have an issue with SharpDX which I filed over in #6042 .
