Before submitting issues, this tool may not always be updated actively. I encourage you to borrow, add, mod, and/or make your own. Remember, all the awesome code out there (and there is a lot) can be taken/modified to create your own custom tools.

Setup - Quick and Dirty

Note: I used Windows 10, Visual Studio 2017 - mileage may vary

  1. Download SharpCradle tool and open up SharpCradle.sln

  2. Compile for correct architecture (x64 or x86), drop binary on target computer and have fun.

Note: architecture of SharpCradle and binary you are retrieving should be the same or it might throw errors.
