Forcing a static constructor to be called C# with Example

While static constructors are always called before the first usage of a type it's sometimes useful to be able to force 
them to be called and the RuntimeHelpers class provide an helper for it: 
 

using System.Runtime.CompilerServices; 
// ... 
RuntimeHelpers.RunClassConstructor(typeof(Foo).TypeHandle); 
Remark: All static initialization (fields initializers for example) will run, not only the constructor itself. 
Potential usages: Forcing initialization during the splash screen in an UI application or ensuring that a static 
constructor doesn't fail in an unit test.
