grpc code first base address

[khalilBerakdar]

Description:
I'm experiencing an issue with the gRPC client library where it seems to be ignoring the endpoint path in the URL configuration. Here's a clear example of the problem:

Scenario:

I've configured the gRPC client using the AddCodeFirstGrpcClient method with the address set to "https://test-api.com/ms/er/"
csharp
Copy code

services.AddCodeFirstGrpcClient<ITestClient>((serviceProvider, o) =>
{
    o.Address = new Uri("https://test-api.com/ms/er/");
}).ConfigureChannel(...).AddCallCredentials(...);

Within my interface definition, ITestClient, I have annotated the service contract with [ServiceContract(Name = "TestService")].

When I call a method on the client instance like this:

await testClient.GetUserExample(new RequestMessage() { Value = value });

The call is unexpectedly redirected to https://test-api.com/TestService/GetUserExample instead of respecting the full URL with the endpoint path (/ms/er/).

Expected Behavior:
I expect the gRPC client to use the full URL I've provided (https://test-api.com/ms/er/) for the endpoint call. It should not omit the endpoint path (/ms/er/) from the URL.

Request:

I'd appreciate any insights or workarounds on how to properly configure the gRPC client to respect the full URL, including the endpoint path. If this is a limitation of the library, guidance on how to achieve the desired behavior or suggestions for alternative approaches would be very helpful.
