Is there any method that I can guarantee execution of a code path within a
thread without a Thread.Abort call interrupting it? I am concerned that a
file write that is done using two calls will not complete if the thread is
aborted before the second call gets a chance to complete.

I thought about setting the priority to highest for the critical calls, but
I was not sure if this would be sufficient or not.

You need a Constrained Execution Region.

There's a lot of subtlety and a lot of restrictions on using them, but
they're intended to provide a solution to exactly the kind of problem you're
describing.

You can look at the safehandle class to see how this is done as well (I
believe it does just this).

What about 1.1 framework?

The only option I know of is the BeginCriticalRegion stuff.
