Those of us who registered with red-gate.com after they bought Reflector from its creator, Lutz Roeder, got an e-mail on February 2 saying the next version of Reflector would no longer be free. It’s the second time in my recent memory that a free and/or open source package for .NET became closed. The first one was NCover, which was probably the best option out there for determining how much of your codebase was covered by unit tests. Even at a price with subscription of $658, it may be a more cost-effective option than paying for the Visual Studio sku that includes team testing tools.
By contrast, the entry-level price for .NET Reflector is relatively low ($35). As a tool, I think it’s valuable enough to the every-day .NET developer to spend their own money for.
