System.IO.FileNotFoundException: Could not load file or assembly 'System.ServiceModel.Primitives, Version=4.5.0.3

[rudidlo]

When trying to deliver message using unary call getting following exception on net4.8
using GrpcWebHandler to connect with service on Http1

GrpcWebHandler grpcWebHandler = new GrpcWebHandler(GrpcWebMode.GrpcWebText, (HttpMessageHandler) new HttpClientHandler());
     return GrpcChannel.ForAddress(this.serviceUri, new GrpcChannelOptions()
     {
       HttpHandler = (HttpMessageHandler) grpcWebHandler
     });

I get following missing reference error

System.TypeInitializationException: The type initializer for 'DefaultProxyCache1' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.ServiceModel.Primitives, Version=4.5.0.3, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

I have fixed it by adding System.ServiceModel.Primitives as my nuget package dependency.
