Summary: 
This course explains what is needed to create custom components by inheriting from the Component, Control, and UserControl classes. Security, versioning, and deployment of these components are examined with the use of .NET assemblies. The capability of .NET applications to extend Internet connectivity is also covered with Web Services using SOAP, UDDI, and WSDL protocols. In addition, the integration of legacy code through .NET's API, ActiveX, COM, and COM+ functionality is discussed, since application development often involves working with existing legacy code.
