  • How to share objects (types) between multiple Web Services

    Posted on March 14, 2012 by in C#, Dotnet

    2) Create two web services Service1. asmx & Service2.asmx
    3) Create a shared class Department.
    4) Create a web method RetrieveDepartment in Service1. asmx
    5) Create another webmethod ModifyDepartment in Service2.asmx which uses the same department

  • How to do custom username assertion in WSE 3.0.

    Posted on March 14, 2012 by in C#, Dotnet

    This article would describe how to write a custom username assertion in WSE 3.0. It is nothing but sending username/password from client to service and service authenticating the same before honoring the request. Article would also describe how to sign & encrypt the SOAP header/body without a fuss. We would extend one or more of the “TurnKey security assertions” provided WSE. Turnkey assertions are nothing but set of security operations packaged by WSE.
    Essentially there are four pipelines in WSE 3.0. We need to inject our custom policy assertions into these pipelines. As simple as that
    1) Sender’s Output Pipe Line :
    2) Sender’s Input Pipe Line :
    3) Receiver’s Input Pipe Line
    4) Receivers Output Pipe Line.
