In the code below:

C#

catch (Exception ex)
{
    MessageBox.Show(string.Format("Msg = {0}; StackTrace = {1)", ex.Message, ex.StackTrace));
    request.Abort();
    return null;
}

..."ex.StackTrace" is grayed out. Why?

What does that even mean, it's grayed out?

"Greyed out" means that, in Visual Studio, the text in question is grey, indicating that it's superfluous (it compiles, but it's unnecessary/redundant/a no-op).

I have no idea. I have never seen that. You must have some option turned on that I don't. Does it work?

I don't know - that exception is not being thrown.

Maybe "grayed out " means stopping running program ..
you check include Exception class or inherit concern class ..

Do the same having debug information enabled. Generally, this is a pseudo-problem. Who cares if it is gray or green?

The problem here is an infestation by a demon. That demon caused you to forget to put a matching close-curly-brace on the second place-holder in your formatted string:

C#

MessageBox.Show(string.Format("Msg = {0}; StackTrace = {1})", ex.Message, ex.StackTrace));
