I know, old knowledge, but I only recently added the below batch files to file collection.
Why? Because since a few Windows versions, the System process uses port 80 because IIS is installed by default in many configurations. And recently I had to do quote a bit of http communication work against a local machine outside the IIS realm.

echo You need to be admin running with an elevated security token to run %0
goto :exit

iisreset /stop
:exit
::pause
exit /b

Most of the times it is me at fault: some process still is using it.
But sometimes, it is devenv.exe (Visual Studio itself) that keeps it locked, even though nothing is running (in fact it can happen right after you loaded the project in Visual Studio 2013).
I think the reason forward declaration of classes and interfaces is possible because they both are reference types, so referring does not impose copying.
Anyway, the trick is this:
You can’t have forward declarations for record types. Define both Implicit operators in the second type
