| generic manner. I use a static method called EntityBase.GetByID(int id)
and a
| member method called EntityBase.Save(). I want to be able to force every
| derived class to implement both of these methods, with this limitation I
| can't though. Is there any workaround? Is there any reason for this
| limitation in the first place?
Neither constructors or static members are allowed to be virtual in C#; you
can only declare virtual (and abstract) instance methods. That is just one
of the few limitations of the language.
Are you sure you want your method to be accessible without having to
instantiate the class it is included in ?
