Difference between Singleton and Static Class

	Singleton	Static Class
1	Single means single object across the application life cycle so it application level	The static does not have any Object pointer, so the scope is at App Domain level.
2	Singleton is a pattern and not a keyword	Static is key word
3	A Singleton can implement interfaces and inherit from other classes and allow inheritance.	Static class allows only static methods  and you cannot pass static class as parameter. Static class cannot inherit their instance members
4	Singleton Objects stored on heap memory	Static class stored in stack memory
5	Singleton Objects can have constructor	Static class will have only static constructor ,so overloading it won’t work
6	Singleton Objects can dispose	We can’t dispose in static class
7	Singleton Objects can clone	We can’t clone in static class
