How do you specify a constraint for the type to be used in a generic class?

234.

class myCLass where T: IMyInterface

class myCLass : IMyInterface

class myCLass constraint T: IMyInterface

not available

class myclass<T> where T : IMyinterface

class myCLass where T: IMyInterface { } this will ensure that the type used to fill the placeholder should be derived from IMyInterface. Fails to compile if the type is not derived from that interface
