AccessViolationException on PropertyAccessor.GetProperty

Question

I have a problem with my VSTO add in. On some random machines I recieve an AccessViolationException trying to use PropertyAccessor.GetProperty.

I couldn't find an explenation on the internet for why this exception accures.

Also it seems there is no way to catch this exception, i use a try catch block that catces (System.Exception), but it doesn't catch it and outlook crashes.

Any ideas on what can be the problem?

Please post the relevant snippets of your code. Does it only happen for a particular property? — Dmitry Streblechenko, Jul 17 '19 at 14:22
What code do you have now? What parameters do you pass to the `GetProperty` method? — Eugene Astafiev, Jul 17 '19 at 16:00

Decorate your method with the attribute [HandleProcessCorruptedStateExceptions]:

[HandleProcessCorruptedStateExceptions]
private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
  try
  {
    //Do something...
  }
  catch (Exception ex)
  {
    //This is catching ALL exception types 
    //even AccessViolationException
    //or OutOfMemoryException
  }
}
