<p>Is there a tool that creates a diff of a file structure, perhaps based on an MD5 manifest. My goal is to send a package across the wire that contains new/updated files and a list of files to remove. It needs to copy over new/updated files and remove files that have been deleted on the source file structure?</p>

<p>Given an empty method body, will the JIT optimize out the call (I know the C# compiler won't). How would I go about finding out? What tools should I be using and where should I be looking?</p>
<p>Since I'm sure it'll be asked, the reason for the empty method is a preprocessor directive.</p>

<p>Apparen... | <p>All things being equal, yes it should be optimized out. The JIT inlines functions where appropriate and there are few things more appropriate than empty functions :)</p>
<p>If you really want to be sure then change your empty method to throw an exception and print out the stack trace it contains.</p>
