Thank you! Looks like a little bit strange )
Do I understand correctly that the instantiated generic types should
not be added to declaringtype?
For ex., I cannot see method body copying, or adding resulting
MethodReference to any type. It just called. Why?
public static MethodReference MakeHostInstanceGeneric(this
MethodReference self, TypeReference type)
{
var m = new MethodReference(self.Name, self.ReturnType,
type)
{
HasThis = self.HasThis,
ExplicitThis = self.ExplicitThis,
CallingConvention = self.CallingConvention
};
foreach (var p in self.Parameters)
m.Parameters.Add(new
ParameterDefinition(p.ParameterType));
foreach (var p in self.GenericParameters)
m.GenericParameters.Add(p);
return m;
}
