I’ve just published a little project of mine on GitHub, called VsDebugFx. It’s a NuGet package which you can install into your .NET project and get more expressiveness during your debugging sessions inside Visual Studio. It’ll let you evaluate expressions that use C# features which are not normally allowed by the IDE, namely: lambda expressions, anonymous types, LINQ queries and implicitly-typed arrays.
I don’t want to repeat myself (DRY anyone?), so if you’re interested in knowing more, go check out the README file about the project on GitHub.
