This is a helper library that allows you to get properties/fields/methods using lambda expressions. Example:

var property = Info.PropertyOf<You>(u => u.Property);

I'm pretty sure I've seen other libraries for that before, but now I can't find them.
LambdaReflection looks cool, but brings in the whole DelegateDecompiler, which feels like an overkill.

NuGet:

Install-Package InfoOf
