My team put this piece of code that used CSharpCodeProvider classes to
do some dynamic c#   scripting in our application.
Everything was fine until the test team uploaded a jpg file instead of
teh c# file...and the compiler compiled it without error.
Does JPG files contain patterns inside that appear like code to teh
compiler?

The idea of compiling jpeg sounds intersting though..
anyone any idea?
