thanks.
there no need utilize nullable(of t) list(of t). utilize list(of t) straight , utilize nothing no value state.
the basic capability nullable(of t) provides value types have no-value state. concept clearer in c# there syntactic difference between no value null , default value default(t). in vb.net though there nothing represents both no value reference types , default value value types.
vb.net generics
