  42
  43 //
  44 // Interfaces are used to prevent the AOT compiler from discovering instantiations, thus forcing the usage of the gsharedvt
  45 // versions of methods. Unused vtype type arguments are used to test gsharedvt methods with ref type arguments, i.e.
  46 // when calling foo<T,T2> as foo<object,bool>, the gsharedvt version is used, but with a ref type argument.
