Anything else we should know about your project / environment?

I tried to add the proto file to the following project file:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net5.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Google.Protobuf" Version="3.14.0" />
    <PackageReference Include="Grpc.Net.Client" Version="2.34.0" />
    <PackageReference Include="Grpc.Tools" Version="2.34.0">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
  </ItemGroup>

  <ItemGroup>
    <Protobuf Include="..\Protos\greet.v1.proto" GrpcServices="Client" Link="Protos\greet.v1.proto" />
  </ItemGroup>

</Project>

I have tried with <TargetFramework>netcoreapp3.0</TargetFramework> and still not working

[JamesNK]

Yes. It will be in 2.35.0

Hi @JunTaoLuo . I am a little confused on what the fix is. I am trying to run dotnet-grpc add-url and get an erorr Unhandled exception: System.IO.FileNotFoundException: Could not load file or assembly ‘System.Collections.Immutable, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’. The system cannot find the file specified

I assume this is the same issue, but I am not sure what the fix is… I looked at #1167 but still not clear what I need to do?

dotnet-grpc --version shows 2.34.0+3c83ca22186f6db3cbb82a2389e34d21f8f2b703

Am I suppose to have a newer version of dotnet-grpc?
