WPF Error on Non-Development PC - XamlParse

Question

I have an error very similar to the one addressed in this question. I am trying to deploy a small c#/Xaml utility on 6 work machines. 4 of the machines run the utility successfully and 2 do not. All machines are windows XP and have .Net frameworks 1-4 installed (my app is compiled against 4.0 and all machines have both client and extended redistributables installed).

On running the utility, I get the standard "... has encountered a problem and needs to close." On viewing the error report contents, the problem seems to occur in System.Windows.Markup.XamlParse.

I have run .Net 4.0 online installer in "repair" mode and still I get the same problem. I have tried all the suggestions from the post linked above:

• The file is deployed alongside a DLL which is present and correct.
• UI cultures are identical.
• All computers are up to date from Microsoft Update.
• The assembly does not contain any external resources which are referenced in XAML.

I don't really know where to start with debugging this one. Any suggestions?

Answer 1

I would suggest setting up remote debugging on the machines that are having the problem and then adding this to the startup code:

while (!System.Diagnostics.Debugger.IsAttached)
{
    Thread.Sleep(100);
}
