any sort of tool required for quality analysis ?

Probably the best known code analysis tool for .NET is FxCop which has been around 'for ever' and is now in version 10.0 and comes bundled with some versions of VS.

There's also a newer complementary tool called StyleCop.

Both of these tools are free. The main difference between them is that FxCop works from the compiled assembly but StyleCop works from the source code.
