This is the official MediaCrush app for Windows. It sits in your taskbar and lets you upload files directly, as well as providing a screenshot mechanism. Click the icon to upload files, or press Ctrl+PrintScreen to take a screenshot.
To compile, you should have Visual Studio 2012 or better, SharpDevelop 4.0 or better, and .NET 4.5. You can compile it from a command line like so:
msbuild.exe /p:Configuration=RELEASE
And you'll get binaries in MediaCrush/bin/Release/. You can also open up the .sln file with Visual Studio or SharpDevelop and
compile it like normal.
