also i have added Noogen.validation.dll reference.
I m using visual studio 2010
Dot net framework 4 client profile.
also following warning also gets.

The referenced assembly "Noogen.Validation" could not be resolved because it has a dependency on "System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies not in the targeted framework or consider retargeting your project.

It looks like a wrong target framework. Isn't the error message apparent? If not, do the following: open the project properties, first tab, "Application", locate "Target framework" and change the target framework. Probably, it is set to ".NET Framework 4 Client Profile". Change it to ".NET Framework 4".

All right, first, this is a separate and unrelated problem, second, you did not provide the information useful for helping you.

hi,
The problem regarding Noogen.Validation error are you missing a using directive or an assembly reference?. has been solved as per your solution. Now while applying rules thr the provider after executing the application it is not working:

Perhaps you need to ask a separate question and show a comprehensive code sample, explain what is "not working" exactly, starting from what would you expect, and so on.

Hi,
I worked with problems and solved by writing code for rules which were generating automatically.
Thank You.
