C# - Build Errors

[keith...@gmail.com]

When I am opening the C# src project it keeps failing to build. Should this work out of the box or am I missing something?

I think the highlighted "error" is just a warning (and it also says the Castle.Core dependency was resolved fine).

The actual error seems to be that there is no grpc_csharp_ext.dll library pre-built (you need to build the native library grpc_csharp_ext.dll before you can build the C# project - otherwise it fails to copy the .dll to the project output).

The native library can be built using cmake and gets built automatically if you just run:

python tools/run_tests/run_tests.py -l csharp -c dbg --build_only

(the step is mentioned here: https://github.com/grpc/grpc/tree/master/src/csharp#build-from-source)

Also, it looks like you are trying to build on ARM - which is not officially supported so you might be have some extra trouble building the grpc_csharp_ext.dll.

Thanks for your reply :) I have tried to follow the steps in this thread : https://github.com/grpc/grpc/issues/11686

But I also got stuck. Tried tagging person who managed to build for ARM but he did not reply.

I just found out that the "Castle.Core" dependency problem can indeed fail the build if you have a new enough version of dotnet SDK version installed.

I'll create PR with a fix, but in the meantime you can easily fix this yourself by updating Moq to 4.8.2 here: https://github.com/grpc/grpc/blob/0dc7c5996ce5091a96632919a3e3befe351b44d0/src/csharp/Grpc.IntegrationTesting/Grpc.IntegrationTesting.csproj#L22
