Hi sandhya,
Questions like this should go under .netTiers - General Support, so please remember in the future 
What seems to be the problem/error after you have created your solution? Have you tried compiling the solution before trying to run/access it? Normally I would generate the solution using the .NET Tiers templates, and then I compile the solution, and then it creates the .dlls and then it is ready to be run.
