Decompiler and repacker for .NET

Question

Is there a tool which allows me to decompile a .net dll, edit it and repack it back to dll again?

I use dotPeek a lot. It can't repack or edit.

Answer 1

While Reflector is cool - but it's not free.

There is Mono.Cecil - which is a lower level tool that can modify assemblies. The two I now use most often are:

JustDecompile and DotPeek

Answer 2

Reflector is one of a kind. I have successfully created c# projects from binaries and recompiled them.

Bear in mind that protected assemblies are difficult to decompile, also they may be obfuscated or protected against ILDASM.
