When you refactor a method using Resharper 8 and the method arguments do not depend on instance variables of the class, a static method is constructed. However, an instance method could also have been created.
Is a static method created for performance reasons?
TIA.

That's right. Here’s what the MSDN documentation has to say about it:
Members that do not access instance data or call instance methods can be marked as static (Shared in Visual Basic). After you mark the methods as static, the compiler will emit nonvirtual call sites to these members. Emitting nonvirtual call sites will prevent a check at runtime for each call that makes sure that the current object pointer is non-null. This can achieve a measurable performance gain for performance-sensitive code. In some cases, the failure to access the current object instance represents a correctness issue.
