MetroIdeTemplate is a free and open-source template for Modern (aka Metro) styled IDE-like applications. Based on Assembly, this project drops Blamlib-based support for editing Halo.

Although MetroIdeTemplate's codebase is a fork of Assembly, it is a spiritual descendant of MetroWPFTemplate -- an earlier fork of the Assembly codebase which was supposed to provide a good starting point for WPF applications with a Metro appearance. However, that project contains numerous rough edges and lacks updates. MetroIdeTemplate attempts to succeed MetroWPFTemplate by incorporating recent improvements to Assembly with additional polish and generalization.

As a fork of Assembly, MetroIdeTemplate falls under the GPLv2+ license.
