Access protected const from base class in attribute

Question

I have a base class with a constant

public class TestClassBase
{
    protected const string Foo = "Bar";
}

which I can consume in C# as follows

[Trait(Foo, "")]
public class MyCSharpTestClass : TestClassBase
{
}

How do I consume it in a F# class? Foo is not recognized by the compiler.

[<Trait(Foo, "")>]
type MyFSharpTestClass() =
  inherit TestClassBase()

The error I get is: FS0267 This is not a valid constant expression or custom attribute value.

EDIT

[<Trait(Foo, "")>] yields: FS0039 The value or constructor 'Foo' is not defined. Maybe you want one of the following: floor.

[<Trait(this.Foo, "")>] yields FS0039 The value, namespace, type or module 'this' is not defined. Maybe you want one of the following: ThisAssembly.

[<Trait(base.Foo, "")>] yields FS0039 The value, namespace, type or module 'base' is not defined. Maybe you want one of the following: Base.

[<Trait(TestClassBase.Foo, "")>] yields FS0039 The field, constructor or member 'Foo' is not defined.

@FyodorSoikin see my edit. Your suggestion did not work unfortunately. — David, May 29 '17 at 18:46
