why reuse types in referenced assemblies

 

I'm following instructions to add a service reference to my project and, by default, the "reuse types in referenced assemblies" is ticked.

If I leave it ticked, I get ambiguous warnings on controls like Label, which I have to declare fully now.

If I untick it, the warnings go away.

My questions are:

  • Why would I want to reuse types?

  • What does that mean exactly?

  • What are the problems if I don't use it?

    • I know I'm answering like two years late, but...

    1- To avoid having two classes with the same name, types, etc.

    2- It means that, if you control both the server code and client code and define the datacontract classes in a separate assembly (and add a reference to it in the client code), the svcutil will not generate new classes but instead will re-use your already-defined classes that you use for the server.

    3- Generally none if you 1) do not control the server code or 2) specify full namespaces for everything. You may get ambiguous warnings if you're in the same solution for server and client code.
