so here is my implementation, despite all references you CAN USE unsafe code in NETMF, just not the "fixed" keyword.In order to use this open your project's Properties and tick the "Allow unsafe code" checkbox under the Build tab.
You are free to use the code in any type of project(commercial, open-source etc.), you can modify and distribute the code as you wish.
Note that using unsafe code is not documented, so even though it works fine under test conditions, we can't be sure just yet that it doesn't have side effects.
