How to: Define Operation and Parameter Types for ASP.NET Web Services

In Application Designer and System Designer, you can define the operation and parameter types for a Web service provider endpoint on an ASP.NET application. When you define Web service operations and parameters in the Web Service Details window, you can either select a type, reference a type defined in another project, or reference a type that you define later. After you implement the application, you can also define the type in code or by using Class Designer.

NoteNote:

You must first implement the application before you can define an operation or parameter type. If you reference a type that is defined in another project, you must add references to those projects after you implement the application. For more information, see How to: Implement Applications on Application Diagrams and How to: Add and Remove References in Visual Studio (C#).

To define an operation or parameter type

  1. On the diagram, select a Web service provider endpoint on an ASP.NET application.

  2. On the Diagram menu, choose Define Operations.

    TipTip:

    You can also right-click the endpoint to choose Define Operations.

    The Web Service Details window appears.

  3. In the Web Service Details window, right-click the operation or parameter row with the type you want to define and choose Define '<typename>' in the Current Project.

    In Solution Explorer, a class file for the type is added to the associated application project. You can now choose to use Class Designer to visually define the type on a class diagram.

  4. When you are prompted to open Class Designer, choose one of the following:
