How can I define a method with two Generic types and two type constraints?

My Method define is

public ActionResult _Create3<T>() where T:IMyClass, new()

but I want define tow generic type

public ActionResult _Create3<T, G>(G content) where T:IMyClass, new()

Type G must also use interface ImyClass but I Dont know define in where tow type !!!

for example if may be write :

public ActionResult _Create3<T, G>(G content) where {T:IMyClass, G:IMyClass}, new()

but get error.

thanks for answer

You can define multiple where constraints on multiple generic types like:

public ActionResult _Create3<T, G>(G content) where T:IMyClass, new()
                                              where G:IMyClass, new()

Add another where constraint for that generic type:

public ActionResult _Create3<T, G>(G content) 
  where T : IMyClass, new()
  where G : IMyClass, new()
