Unhandled exceptions in Windows Form events are not propagated up call stack

Symptoms
Unhandled exceptions that occur in Windows Form events are not propagated up the call stack to a structured exception handler in the calling procedure.

The Microsoft .NET Framework wraps the message pump in an exception handler. The .NET Framework only handles exceptions that reach the message pump and that the application has not already handled. Therefore, any unhandled exception that reaches the message pump is not propagated up the call stack.

FIX: You may receive a ‘System.Runtime.InteropServices.COMException’ exception when you try to access a WPF application by browsing a Web service

Symptoms
Consider the following scenario. On a computer that has .NET Framework 3.5 Service Pack 1 (SP1) installed, you run an ASP.NET Web service application that is hosted on Internet Information Services (IIS). You use a Windows Presentation Foundation (WPF)-based application to generate content context for the Web Site or Web service, for example, images. In this scenario, when you try to access the WPF application by browsing the Web service, you may receive the following message:

A first chance exception of type ‘System.Runtime.InteropServices.COMException’ occurred in PresentationCore.dll
Additional information: The program issued a command but the command length is incorrect. (Exception from HRESULT: 0×80070018)
Resolution
When the WPF application calls the NtRequestWaitReplyPort function to dispatch a message through a local procedure call (LPC) to Windows Manager Session Manager service (UXSMS) in the DwmGetTransportAttributes function, the E_ACCESSDENIED exception is returned. Then, the DwmGetTransportAttributes function tries to decode the message. However, the message was never handled because it is not a valid packet. Therefore, the code returns E_INVALID_COMMAND_LENGTH and triggers the exception.
