in the _binary_ you'll find PIT_Magic_v1.3.10_Release.zip, as downloaded from somewhere.
Both C# and VB.Net sources should be the same, the source-code, was probably written in VB.Net .
for your safety, please avoid running/using the zip/exe/source,
it is an unofficial source-code for PIT-Magic,
reversed-engineered from for education-purposes only.
