C Sharp

I wanted this page to be called C# but apparently mediawiki did not approve. Oh well. Maybe I will put all things beginning with the letter 'c' here.

Frameworks

What is your favorite .net framework?

Is it MEF? Managed Extensibility Framework

Is it the Entity Framework? So many options.

readonly

Yes, there is a readonly setting for variables. One would think 'const' would be enough. Aren't these the same?

public static readonly string foo = "I am read - only."; // happens at program load
public const string foo = "I am read - only"; // happens at compile time

Check the debugger, you can see before the first line executes that foo = null. Since it happens at load time, you can do this

public static readonly string foo = Something.StringThing();

so the value is set once, and it's done atomically so it is thread-safe.

Preprocessor Directives

What about things in square brackets

That I can't type in a wiki, like "bracket CommandLine bracket"

When would I ever use a Struct?
