AppInfo Editor Beta 1

So I got tired of typing out all the appinfo.ini files, so I made a program which will take the inputs and generate the file.
This is a beta software and is basic. All it can do right now is create/edit an appinfo.ini file. It has no error-checking yet. Also, I didn't include FileTypeCommandLine-extension or ProtocolCommandLine-extension because I didn't feel like parsing the field to add x number of inputs for each extension. I will in the next version, but I wrote this at 0230 today, and I was tired. But I decided to upload it to get comments about it.
Please reply with comments, complaints, and/or suggestions. If anyone wants the source, just let me know and I'll zip it up and upload somewhere.

It is written in .NET so you will need the .NET runtime, which most people should have anyways.
