title: How should i use WellKnownTypes with C#?
body: <p>I am using protobuf and I use Int32Value from <a href="https://developers.google.com/protocol-buffers/docs/reference/google.protobuf" rel="nofollow noreferrer">https://developers.google.com/protocol-buffers/docs/reference/google.protobuf</a>
  if I write <code>import "google/protobuf/any.proto";</code> i get the following error <code>google/protobuf/any.proto: File not found.</code> I haven't found any documentation about it.
  I can't find a way. How should I use these types?</p>
