As DrawString takes a RectangleF, the workaround is to do "New RectangleF" rather that "New Rectangle". ---- Now the bugs. Given: public void DrawString(string s, Font font, Brush brush, RectangleF layoutRectangle) public struct Rectangle { .. } public struct RectangleF { public static implicit operator RectangleF(Rectangle r); .. } And the call above. Then: 1) VBNC should use the conversion operator implicitly. 2) Or explicitly with CType; should succeed but fails with: [[ Visual Basic.Net Compiler version 0.0.0.5914 (Mono 2.4 - r) Copyright (C) 2004-2008 Rolf Bjarne Kvinge.
