c# - Hard Error for password box on Windows Standard Embedded 7 -


I am working on the C # application for the Windows Standard Embedded 7 platform. I have been able to create a Windows Image (using Image Configuration Editor) and install .NET 4.5 Runtime, as well as application software. So far good.

When I run the program, it looks all right - the hardware starts correctly and the software loads its data, however, when I go to the program's "login" dialog (an otherwise Normal WPF dialogue window that gives access to extended functionality), then something strange is happening. This dialog contains a password box, and when I click on that box (or tab focus), the software crashes with a system message box called "unknown hard error". Why does this happen, there is no real clue about this, and it is 100% repeatable? Any ideas about how to diagnose the problem?

This fonts will be created in the image configuration editor while creating an image image for Windows Standard Embedded 7 TrueType fonts must be included, it will not be raised as a dependency in the .NET 4.x template.
