I wrote a C# application for a client a few years ago, but the source code is no longer available. I only have the EXE that I installed on the client’s computer. Is it possible to build C# source code from an EXE?

Reflector and its FileDisassembler add-on.
The source code can be viewed using Reflector. FileDisassembler will convert it to a Visual Studio solution.

When Red Gate announced that the free edition of.Net Reflector will be discontinued, I switched to ILSpy and Telerik’s JustDecompile.

ILSpy is an open-source assembly viewer and decompiler for.NET assemblies.
ILSpy 2.0 was launched on April 15, 2012. In comparison to version 1.0, the following new features have been added:

Reflector is no longer free in general, although open source developers can get it for free: http://reflectorblog.red-gate.com/2013/07/open-source/
However, several firms, such as DevExtras and JetBrains, have made free alternatives:

Denis Bauer’s Reflector and File Disassembler add-in. It creates source projects from assemblies, whereas Reflector merely displays the disassembled source on its own.
ADDED: JetBrains’ dotPeek is my most recent favorite.

JustDecompile by Telerik is a free tool that allows you to generate projects from.NET assemblies.
