Is there an asynchronous version of DirectoryInfo.GetFiles / Directory.GetDirectories in dotNet? I'd like to use them in an F# async block, and it'd be nice to have a version that can be called with AsyncCallbacks.

While building a page out for WPF project the other day I ended up building a page that looked like it had an in-page dialog on it but it was the only thing on the page. My question here is. Has any one created such component that allows for easy creation of these kinds of dialogs. ...

Have you ever been frustrated by Visual Studio not re-evaluating certain watch expressions when stepping through code with the debugger? I have and does anyone here care about pure methods? Methods with no side-effects? There's so many great things about C# that I love, but I can't write pure functions, that is, static methods with no s...
When running a .NET 2.0 WinForms app in a Terminal Services environment, I'm seeing some unexpected results that I can't quite explain. Everything I have read has indicated that JIT'ed assemblies (i.e., not using NGen to create native images) result in all code space being stored in private pages, increasing working set size / memory pr...

I'm looking for drag/size handle implementations or explanations. Perhaps I'm using the wrong nomenclature, but I mean the "handles" that appear around an object (mostly in drawing programs) when you select it and want to perform an operation on that object such as rotate, size, scale, etc... Can anyone point me to an OSS implementatio...
I've got a .NET library in which I need to find all the classes which have a custom attribute I've defined on them, and I want to be able to find them on-the-fly when an application is using my library (ie - I don't want a config file somewhere which I state the assembly to look in and/ or the class names). I was looking at AppDomain.Cu...
Does anyone know or have an idea on how the default implementation for GetHashCode() works? And does it handle structures, classes, arrays, etc efficiently and well enough? Trying to decide under what cases I should pack my own and what cases I can safely rely on the default implementation to do well. Don't want to reinvent the wheel if...
