In C# status server handlers (and also in interceptors on the serverside), you can set the resulting status without throwing an exception by setting ServerCallContext's "Status" property. https://github.com/grpc/grpc/blob/1c73e2c53ddecf3bd45f1c28d23a895fc7cd6e12/src/csharp/Grpc.Core/ServerCallContext.cs#L155
call.Status = new Status(StatusCode.WhateverYouWant, ""); // and then return from the server side handler. A test that demonstrates this is here: https://github.com/grpc/grpc/blob/1c73e2c53ddecf3bd45f1c28d23a895fc7cd6e12/src/csharp/Grpc.Core.Tests/ClientServerTest.cs#L129 On Tuesday, April 3, 2018 at 11:25:18 AM UTC+2, Joseph Vaughan wrote: > > I have a few instances where I'd like my gRPC server to reject an RPC call > using the newly introduced Interceptors functionality.
