[C#] a own Launcher in Work.

Just put a simple for to count:

-Pseudocode
----------------------------
get the version from file
get the version from server
FOR current_version = file_version to server_version
download patch
apply patch
IF error THEN
print a message
break loop
ENDIF
save current version to file
ENDFOR
update done

I suggest learning C# from the beginning, because I see you dont even know the basics(expressions, loops, etc).
