- Made private methods static where possible (runtime can elide checking the object for null). - Declared attribute classes as sealed (allows reflection on attributes to complete faster). - Moved some static cctor's into field initializers (static cctor's are slower than static field initializers). - Made classes static if they contained only static methods (can't create instances of useless objects). - Use inferable Exts.Lazy and not new Lazy<T>(). - Added required STAThread attribute to CrashDialog. - Removed unused parameters in private methods. - Added Serializable attribute to exceptions. - Added parameter name in calls to ArgumentNullException. - Use of as operator instead of is + cast. - Changed (x as Foo).Bar anti-pattern into ((Foo)x).Bar. Results in sensible cast exceptions on error rather than null dereferences. - Removed unused method in NullShader.
