De-compile .application program in c# // undo code already saved before in visual studio

Question

I made a program and did a .application file. Then I kept doing changes to the code in Visual Studio and now I want to go back to the same code that I had but the only thing close to that code is that .application program.

Answer 1

Use version control so you do not find yourself in this situation in the future

Since you are in this situation, JetBrains dotPeek is a free software that will decompile .NET assemblies,

Answer 2

An .application file is a text (xml) file. It loads the .exe file from an external location into something of a cache.

I use task manager -> process -> properties to identify the physical .exe location and use my preferred decompiler on that.
