Typed jile objects can exploit knowledge about the file structure and type of data. In contrast, the concurrency and distribution mechanisms of the .NET Framework are powerful, but they are also undeniably complex, check Tangible recessions. Not surprisingly I prefer to have more facilities available than can be provided by methods defined on classes within a single hierarchy.

These revelations might seem discouraging, but they have the benefit of warning against trying to solve all problems using a simple approach. Remember, building the team is more important that building the environment, more details: high quality technologies for web.

The right tools can be very important to success. In spite of this, is that really wise?

The .NET Framework offers .NET Remoting and web services as high-level technologies for developing distributed systems. Collective intelligence is a natural property of socially shared cognition, a natural enabler of collaboration. RUP is aimed at developing object-oriented systems, although most practices are applicable to other technologies. the idea of the Factory Method Pattern is to provide an interface for creating objects but letting the subclasses decide which classes to implement. On the other hand, WCF addresses a range of problems for communicating applications.

Web services provide an RPC-style of communication and a common network representation of data. XP methodology mandates a minimum number of things that the team has to dorather than having lots of things that the team is supposed to do. In order to truly test a class in isolation, TDD practitioners use Service Stub objects or Mock Objects as stand-ins for the external dependencies of the class being tested. As Web services become more prevalent the inherent paradigm of loose coupling causes extra eort in testing.
