class A can implements I1 or I2 depending on how it is constructed

This is a dead giveaway for poor design. Inheritance hierarchies are telling you what operations you can do on an object, and you should be able to tell from the type of something what you can do with it. That is, an instance of A should always be treatable as an I2, or never.
 
What you almost certainly want to do is:
 
interface I1 {
 void A();
 void B();
}
 
interface I2 : I1 {
 void C();
 void D();
}
 
class A : I1 {
 // Implementations of the I1 functionality, and the I1 type constructor
 public virtual void A() {}
 public virtual void B() {}
}
 
class A2 : A, I2 {
 // Implementations of the I2 functionality, and the I2 type constructor
 public void C() {}
 public void D() {}
 
 // You can also override implementations from A
 public override void A() {
  base.A();
  // other stuff
 }
}
