Someone with more CPU and physical RAM than I have should run it and see where it ends...

No wonder, always use StringBuilder for string concatenation in a loop.

StringBuilder inner = new StringBuilder();
 
DateTime startTime = DateTime.Now;
   
for (Int32 i = 0; i < 500; i++) {
   inner.Append("      public Int32 Method" + methodCount.ToString() + "() {" + Environment.NewLine +

   StringBuilder code = new StringBuilder(pre);

TimeSpan ts = DateTime.Now - startTime;

Anything to add?

inner.Append("      public Int32 Method" + methodCount.ToString() + "() {" + Environment.NewLine +

A) I don't think there's any need for including the NewLines.

B) Why step by one? Why not double methodCount after each successful compile?
