WaitAll to support calls from WindowsForms
We have multi-threading application that uses WaitHandle.WaitAll methods. It works fine, when called from ASP.NET, but when it is called from WinForms test harness, it causes the error "WaitAll for multiple handles on an STA thread is not supported.". I've included the workaround and moved code to helper function. However I needed to call the function with different parameters List<ManualResetEvent> and List<WaitHandle> . Even if ManualResetEvent is derived from WaitHandle, there is no ......
