Convert Extension Method to Plain Static refactoring

This refactoring helps you convert an extension method to a static method and update all usages in the current solution accordingly.

Consider the following example:

            
public static void DoSomething(this string s)
{
}

private static void Test(string str)
{
  str.DoSomething();
}

        

            
public static void DoSomething(string s)
{
}

private static void Test(string str)
{
  DoSomething(str);
}

Place the caret at the declaration or a usage of an extension method in the editor, or select it in the File Structure window window.
Do one of the following:
- Press Control+Shift+R and then choose Extension Method to Plain Static.
- Right-click and choose Refactor | Extension Method to Plain Static from the context menu.

The refactoring is carried out without requiring you to specify any further options.
