The code samples in this chapter show two different methods of invoking a selected webMethods service from the context of the Microsoft .NET environment. The invocation uses the webMethods .NET API. The webMethods .NET Client API functionality is supplied in a set of DLLs. You need to reference these DLLs by means of a using statement. The examples in this chapter do not create whole executables; rather, they show how to generate objects you can use in your own code.

For the first example, the webMethods add-in for Microsoft Visual Studio allows you to select a service from a running Integration Server and generate a C# or Visual Basic class. This class encapsulates the integration service, allowing for interaction with the service in an object oriented way. This example is described in Invoking a Service using Visual Studio.

If you are familiar with the Java Client API for Integration Server, you may prefer to use the standard IData pipeline interface for invoking Integration Services. For more on using IData, see Invoking a Service using Java Client API from Designer.
