See this blog posting: http://blogs.msdn.com/ericlippert/archive/2009/06/22/why-doesn-t-c-implement-top-level-methods.aspx (…) I am asked “why doesn’t C# implement feature X?” all the time. The answer is always the same: because no one ever designed, specified, implemented, tested, documented and shipped that feature. All six of those things are necessary to make a feature happen. All of them cost huge amounts … Read more
Change the “MSBuild project build output verbosity” to “Detailed” or above. To do this, follow these steps: Bring up the Options dialog (Tools -> Options…). In the left-hand tree, select the Projects and Solutions node, and then select Build and Run. Note: if this node doesn’t show up, make sure that the checkbox at the … Read more
I like using generic types this way. In particular, I often have private nested generic classes for precisely this purpose. The main thing I like about it is that it’s hard not to get the initialization right this way (in terms of thread safety), given the way type initialization works. The only problem is what … Read more
It’s a managed pointer – while * marks a pointer to an object that is unmanaged, ^ points to a garbage collected object (handled by the framework). Read this for more information about the way pointers are handled in .NET.
You need to make a clear distinction between the CLR (i.e. the “runtime”) and the framework libraries (i.e. the “framework”). You execute your code on or with the first, your code is compiled against and uses the later. Unfortunately when using the the term “.NET version” one is usually referring to the whole package of … Read more
Well, start by asking yourself what could possibly go wrong with class C<T> : T { }. A huge number of things come immediately to mind: What if T is a struct? What if T is a sealed class type? What if T is an interface type? What if T is C<T>?! What if T … Read more

The default stack size for a .NET application is 1 MB (default is 256 KB for 32-bit ASP.NET apps and 512 KB for 64-bit ASP.NET apps), but you can change that. For the application you can change the default size by modifying the PE header of the executable. For threads you create, you can use … Read more
Using is can hurt performance if, once you check the type, you cast to that type. is actually casts the object to the type you are checking so any subsequent casting is redundant. If you are going to cast anyway, here is a better approach: ISpecialType t = obj as ISpecialType; if (t != null) … Read more
If you think of the objects in memory as a tree, the “roots” would be the root nodes – every object immediately accessible by your program. Person p = new Person(); p.car = new Car(RED); p.car.engine = new Engine(); p.car.horn = new AnnoyingHorn(); There are four objects; a person, a red car, its engine and … Read more
