I've a solution which works:

NETCallGenericStaticMethod[classtype_ method_, type_, arguments___] :=
   Module[{m1, m2, t1, t2},
   t1 = GetTypeObject[classtype];
   m1 = t1@GetMethod[method];
   t2 = GetTypeObject[type];
   m2 = m1@MakeGenericMethod[{t2}];
   Return[m2@Invoke[Null, arguments]]];

Any other idea?
