But when will linux start supporting windows gui apps? It kinda irks me that Microsoft crows on and on about how they love open source now, yet still haven't committed anything that makes this relationship more than a 1-way bridge.
They don't own all the IP used in Windows. Even if they wanted to open source Windows, they couldn't without a very expensive licensing agreements with all of the rights holders of technologies they have licensed.
Also in this update: GPU compute support. Hopefully these two come together to make GPU gaming possible on WSL... That would make porting Windows games to Linux slightly more frictionless.
