Please inform if visual studio supports load test of .net4 applications.
Client Application = WPF (Desktop)/xbap
Application Server/communication = WCF (Deployed in IIS)
Database = SQL Server 2008
Some tools playing back the recorded HTTP traffic without any processing (except for dynamic targets contained in cookies e.g. session id, user id, etc.). If WCF service requires any processing by the client then load testing won't work correctly because load testing tool can't handle any processing of the WCF data.
Does Visual studio record and serialize the communication of WPF/xbap application using WCF over http to communicate with server?
Let me know if more information is required for reply.
