Hi,
I'm having an issue with client-side streaming in C#. When my client code
in a VSIX package tries to call a service that returns a stream, I get the
following exception:
An exception of type 'System.IO.FileNotFoundException' occurred in
Grpc.Core.dll but was not handled in user code
Additional information: Could not load file or assembly
'System.Interactive.Async, Version=3.0.1000.0, Culture=neutral,
PublicKeyToken=94bc3704cddfc263' or one of its dependencies. The system
cannot find the file specified.
The version number is suspiciously 3.0.1000.0 instead of 3.0.3000.0. I
noticed that the project references version 3.0.3000.0. This reference got
added automatically when I used nuget manager to add grpc. On the other
hand, grpc.core seems to depend on 3.0.1000.0.
These lines were automatically added in my app.config, and I thought it's
supposed to prevent the issue I'm having, but sadly that's not the case:
<dependentAssembly>
<assemblyIdentity name="System.Interactive.Async"
publicKeyToken="94bc3704cddfc263" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-3.0.3000.0"
newVersion="3.0.3000.0" />
</dependentAssembly>
The same client works fine with simple RPC, only streaming RPC causes a
problem. (More specifically, I call an endpoint that takes a simple input
and returns a stream.)
For a sanity check, I created a dummy Class Library project, but there I
don't get the same issue, streaming RPC works just fine. My real target is
a VSIX project, net46.
How can I make this work in a VSIX project? Or, is there a way to consume a
streaming output without using System.Interactive.Async? Although
ultimately I would like to be able to consume a stream asynchronously,
synchronous mode could be acceptable in the short term.
Thank you,
Janos
