Field type is less accessible than field

Question

I have the following declarations:

public static class Helper
{
    public static Func<T1,T2, string> myFunc = (t1, t2) =>
    {
        var result = string.Empty
        //do some things with params t1 and t2, and build a string
        return result
    };
}

and I am consuming it like this:

var myString = Helper.myFunc(t1, t2);

in a different class. It does not compile, it says "Inconsistent accesibility: field type ... is less accessible than field Helper.myFunc" I understand that it has to do with the anonymus declaration, but how can it be solved?

Answer 1

Check that T1 and T2 also accessible in this code

var myString = Helper.myFunc(t1, t2);
