I'm working on a WPF application, and I'm curious about what it would take to rewrite this application to a Surface application if we want to control it through multitouch some day. Is it likely that we can reuse big parts of our WPF application and transfer it smoothly to Surface, or is Surface completely different, and we probably ha...
I found that while trying to find the owning toolstrip of an item, it wasn't a easy as just looking at the owner of the item. Below is some pseudo code that I think should work. Can anyone see any problems with this or should it work in all cases? (1) Is type of Item.Owner a ToolStrip? (2) Yes, Return Item.Owner (3) No, Item = Item.Ow...
I'm working on creating my own DI framework that creates delegate factories as a learning exercise. My way of building typed delegates is to use expressions to create a function that calls a static method with reference to my container and any constructor params.

I have an IronPython script that uses the TPL and Parallel.ForEach to process files using multiple threads. In C# I can use Interlocked.Add and Interlocked.Increment to change global variables in an atomic thread-safe operation, but this does not work in IronPython because integers are immutable. I currently have a simple Results class t...

This question is related to: How do I determine the intersection point of two lines in GDI+? (great explanation of algebra but no code) How do you detect where two line segments intersect?

I think I have my brain halfway wrapped around the Dynamic Types concept in C# 4, but can't for the life of me figure out a scenario where I'd actually want to use it. I'm sure there are many, but I'm just having trouble making the connection as to how I could engineer a solution that is better solved with dynamics as opposed to interfa...
For my current project, we're using some CLR 2 based mixed mode assemblies. In order to use these from within a .NET 4 targetted assembly, I know you have to add useLegacyV2RuntimeActivationPolicy=true to the <startup> element within app.config. I understand that this changes the activation policy, causing these mixed-mode assemblies t...

I have a compiler that targets the .NET runtime (CLR). The current version of the compiler is written in standard C++ (non-managed). The compiler currently lacks support to reference assemblies at compile time, so the way I "import" .NET libraries is with a utility stub generator that is written in .NET, which reflects any assembly and e...

On this page, a commenter writes: Do NOT ever use .ToUpper to insure comparing strings is case-insensitive. Instead of this: type.Name.ToUpper() == (controllerName.ToUpper() + "Controller".ToUpper())) Do this: type.Name.Equals(controllerName + "Controller", StringComparison.InvariantCultureIgnoreCase) Why is this way p...
