I have created a public static class utils.cs I want to use it in other classes without prefixing method with utils, what\'s the syntax to do this ?
As a minimum, you have to specify at least the class name. All the using directive does is allow you to leave off the namespace. You can also use the using directive to specify an alias Instead of the entire namespace.class name, but then you have to use the alias...
using MyClassName = Namespace.MySubNS.OtherNameSpace.OriginalClassname;
MyClassName X = new MyClassName();
