In this post we introduced gRPC and its .NET implementations. In some cases, you’ll need to use a gRPC client from a legacy Win32 process but, since the NuGet package of gRPC C# is based on the x64 C++ native library, it will not work as expected.
Luckly, a solution is really simple:
- clone the gRPC repository from github
- open the Grpc.sln in
- create a new build configuration and set it to x86
Before start to build, you need to build the C++ library. You can proceed in two ways:
- follow the steps on building page
- be sure that you have the x86 version of
To get the libraries, create a new project and add a nuget reference to Grpc package. Then go to
packages\Grpc.Core.2.24.0\runtimes\win\native and copy the
grpc_csharp_ext.x86.dll library in the previously mentioned
cmake\build\x86\Release folder. Finally, be sure to rename the library in
grpc_csharp_ext.dll. Now you’ll be able to build from Visual Studio 2019.
