ILSpy is a free alternative to Reflector
There was some controversy when Red Gate announced they were turning the extremely popular (and free) Reflector tool into a commercial product.
One reaction to this is the ILSpy project (IL standing for Intermediate Language - the abstraction code between source code, such as C# or VB, and actual machine code).
ILSpy is being actively developed, as recently as today the support for LINQ query expressions was explained at the SharpDevelop blog.
The latest ILSpy source code and binaries can be downloaded here. The screenshot above was taken while using the ILSpy M2 release, 184.108.40.2067.
Easiest way to get started is to:
- Download the ILSpy binaries
- Unblock the ZIP file
- Extract the ZIP file somewhere
- Launch ILSpy.exe
