Patcher tool

[veler]

Is your feature request related to a problem? Please describe.
As a developer working on a large desktop app, I often need to patch some dlls of an existing program. Doing this is slow, recurrent and prompt to mistakes. For example, we need to do a backup just in case if we break anything important.

Describe the solution you'd like
Consider doing one or multiple tool(s) similar to https://github.com/gundermanc/tools#windows-application-developer-tools but with a GUI.
It could have the following features:

• Start any Visual Studio instance
• Reset them, stop them.
• Build automatically a solution and patch the output to a given location.
