Implementing System.Type
f#

Hi there, I need to implement a class which inherits from System.Type, but I keep getting an error:

error FS0191: The override 'get_Module : System.Reflection.Module' implements more than one abstract slot, e.g. 'System.Type.get_Module() : System.Reflection.Module' and 'System.Reflection.MemberInfo.get_Module() : System.Reflection.Module'

System.Type is an abstract class, which inherits from System.Reflection.MemberInfo and both have an abstract property named 'Module'.

So my question is how do I support an implementation for both?

(Code sample:)

type Type() as self =
inherit System.Type()

...

override self.Module
with get() : System.Reflection.Module = raise (new System.NotImplementedException())

...

Without the type specification I got another error message, which I assume is also related to the fundamental problem, that the Module property is defined in both abstract classes.

.

I am not stuck with this problem - I made a workaround, by creating a new abstract class in c#, which doesn't seem to have this problem. (If it had, I think the shadowing 'Module' property in System.Type had been removed before .Net was released.)

public abstract class TypeRedirection : System.Type
{
public TypeRedirection()
: base()
{ }

public override System.Reflection.Module Module
{
get { return this.ModuleRedirected; }
}

public abstract System.Reflection.Module ModuleRedirected
{
get;
}
}

Good workaround.

This is an F# compiler bug, which I've just logged. Thanks!
