WebAssemblies File Download/Upload with gRPC API

Project Details: I'm looking for a sample project that uses the environment below capable of clicking a button on the client's web browser to request a file. Using grpc-web api, download the file to the client's computer as per their browser settings. (pdf, excel, word, compressed zip... other docs) Another button that illustrates uploading a file. So the client gets a browse dialog where they can select an image not larger than 'x' and upload the file to the server. All with grpc-web api Environment: C# .net 6.0 VS 2022 grpc-web api with protobuf Blazor WebAssemblies The result will include all relevant files including the protobuf and byte chunk management for larger files
