I'm a big fan of LoadGen as well as BizUnit. Combining the two makes them even better. The latest LoadGen version, LoadGen 2007, also has support for WCF which makes it a "must have" in the testing toolbox. The problem is that the dll's in this version is not signed with a public key token and therefor cannot be used in BizUnit. If you want to create LoadGen test cases in BizUnit, but are not intrested in using new functionality such as WCFTransport, you can solve the problem by just downloading...
