You can design any C# Class as a Singleton Class. By doing so you can not use it any other way.
Or you can design your Classes as Standard Classes and turn them with this Class into a Singleton:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
Then simply turn a normal Class into a Singleton via:
1 | Singleton<MyClass>.Instance.MyMethodCall(); |
.
