Can anybody suggest a tool for testing VB.net applictaion.I know WR,LR,RR
My suggestion is QTP

You could take a look at TestComplete from AutomatedQA.
Look at the tools advertised on this site. Most tools either standard or with add-in will work with VB.net

Test Partner can do .Net testing w/o extra add-ins and is cheaper than QTP.
BTW, if by WR you mean WinRunner, WinRunner does not support .Net Applications.
