Any idea what is wrong here ?

Thanks

This type of exception is common when some part of your main window constructor or load operations fail. If you can get your hands on the stack trace, look to the inner exception and you will probably find the real issue.

I had this problem because I was showing a form from in Application constructor. This form was using Style="{StaticResource XYZ}". This static resource was defined in the application's XAML file.

I solved the problem by showing the form at a later stage in the application, when the Application object was fully constructed.

I had the same exception report. I could solve it by using the windbg program.

• download the windbg x86 (not x64) version.
• open the .exe file of the app in it (File menu -> open exe.)
• run these commands to see the real exception:

After the analysis, I found that the System.Net.Http.Formatting assembly was missing from the system.

0:000> g
0:000> sxe clr
0:000> g
0:000> !loadby sos clr
0:000> !CLRStack
0:000> !PrintException

Exception type: System.IO.FileNotFoundException
Message: Could not load file or assembly 'System.Net.Http.Formatting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
    InnerException: <none>

the only thing I can think of is whether both boxes have same .NET version on it. NET 4 has some new features (re XAML parser) that 3.5 SP1 doesnt have

I noticed a similar behavior when installing a ClickOnce app on a clean machine. I solved by setting the requirements of the app for install both .Net 4 and .Net 3.5 full.

It was not happened anymore.

Make sure you are build in the correct architecture x86 or x64 when you run on the target machine. I face the same problem as well, the app able to run on my thumbdrive FAT32 however it failed on another machine with Windows 7 - 32bit (I know Windows 7 with 32bit is quite odd though) see http://social.msdn.microsoft.com/Forums/vstudio/en-US/8f803f28-dfda-4be5-9e8d-f7d82db95961/c-wpf-systemwindowsmarkupxamlparseexception?forum=wpf
