Running Orleans via project references for debugging

I am trying to diagnose a serialization issue. So I added orleans as a git submodule and changed nuget reeferences to. project references throughout my project. But when running orleans via project references, it is not able to find any of the grain implementation classes.

fail: Microsoft.Extensions.Hosting.Internal.Host[11]
      Hosting failed to start

This is not exclusive to the OrleansDashboard (which I am also referencing by source so that it may use project refs vs nuget packages)

I apologize if this is a duplicate or there are docs for running agains project references. I could not find any.

Your help is appreciated.

I have to tell you, that is not a supported scenario. It would be easier to add your project within Orleans, since the build system will work with less hassle. Still, it can probably be made to work. You will likely need at least two things:

  1. Reference the Directory.Build.props, Directory.Build.targets and possibly Directory.Packages.props files from corresponding files in your tree

Eg, you might have something like this in your Directory.Build.props file

<Project>
  <Import Project="./orleans/Directory.Build.props"/>
</Project>
  1. Add <OrleansBuildTimeCodeGen>true</OrleansBuildTimeCodeGen> to all of your projects in a <PropertyGroup>

@ReubenBond ,

Thank you for your quick response. Method above works. Completely understand that it is unsupported.

Glad to hear it worked for you, @dashkan!
