Is there any way to maintain the same functionality in the code below, but without having to create the delegate? I'm interfacing with a 3rd-party API that contains a number of various DeleteSomethingX(ref IntPtr ptr) methods and I'm trying to centralize the code for the IntPtr.Zero check. private void delegate CleanupDelegate(ref IntP...
I have a contract in the same signature as an Action<T> delegate: [ServiceContract()] interface ISomeService { [OperationContract()] void DoSomething(object data); } Will the client wait for the server side method execution to finish?

I've been toying with the idea of building a web-based Roguelike game using Silverlight (or maybe just a desktop game using WPF). If you don't know what a Roguelike is, it's a type of graphical RPG where the graphics are rendered using text.

I need to implement a feature in my application where these words are going to "swim" around in the background, basically I need to pick a point in front of the leading letter of the word, and swim to it using a "wavey" style. I also need to avoid the walls, so it turns in time, among other 'fish like' behaviors it needs to implement. ...

If I needed to escape a double quote character within a string literal I'd use two consecutive double quotes as follows: Dim name = "Chuck ""Iceman"" Liddell" However, it doesn't seem like consecutive # works the same way. The compiler is expecting a compiler directive to follow the # character, even when its enclosed in double quote...

How would I reduce this overhead without encoding and decoding everything myself? [<Serializable>] type Response = | FileSize of String * int64 | FileD...
It's not possible to set a connection timeout on a .NET remoting call. Documentation occasionally refers to TcpChannel properties that allegedly do this, but discussions and the most recent docs I've found indicate that this is not possible. One may set a timeout on the remoting call itself, but not on the initial connection attempt. ...

Edit-And-Continue is one of my favorite debugging tools which I have previously used on C# based Winforms and ASP.NET projects. However, I'm running a Silverlight 3.0 application on VS 2008 and whenever I try to make a change (after breaking) it says "Changes are not allowed when debugging Silverlight applications". Also there isn't an "...
