Does this mean that Mono will no longer be necessary for cross-platform C# use?

Open-sourcing .NET doesn't magically make it work on other platforms (a not-insignificant chunk is Win32-specific, for example). But it certainly makes the Mono team's job easier.

They say open source, but not which license they're going to use. It may not be possible to integrate with anything in practice, or as free as developers would like it to be.

It would pretty dumb of them to take this step and then pick a license which wasn't permissive enough to make it happen. Plus, given that they mention they're working with the Mono team on this, I'm sure they're going to get good advice.

AFAIK, it will be MIT licence.

Edit: Yep, MIT. It's not like it's secret: https://github.com/dotnet/corefx

It's MIT (and there's also a patent promise).

https://github.com/dotnet/corefx/blob/master/LICENSE

They are using the MIT license.

Nope but Microsoft is making it work on other platforms. From the opening line:

Mono (the code) and .NET Core will merge (per Scott Hanselmann)

Microsoft will (in partnership with Mono the project) ensure that .NET core and server stacks run on Linux and OS X.

They've just demonstrated deploying an ASP.NET MVC5 application on Linux, running inside a (Linux) Docker container and being remotely debugged from Visual Studio on Windows. Which seems to indicate that they are already pretty far down that road.

Would love to see that demonstration, do you have a link for that?

In reading the article, it sounds like they're going to work with the Mono team to bring it everywhere.

They've announced a .NET core CLR for windows, mac and linux - supported by Microsoft - so sounds like there'll be options (either use Microsoft or use Mono)...

No I think they are providing open source libraries of the server stack which is written in c#. Still needs mono to compile to linux/mac but now mono won't have to (re?)implement those, they can all share the same MS c# code

Only if it's easy enough to port, and I doubt it would be. Although Mono will definitely gain from the original source code.

It does say that they are "expanding .NET to run on the Linux and Mac OS platforms".

"To further support cross-platform mobile development with .NET, as part of their strategic partnership, Microsoft and Xamarin..."

I would be pretty shocked if MS just suddenly dropped their won linux/mac implementation. Xamarin and the mono team have been working on this for a very long time. MS is just bringing them further into the "legit" fold

Yeah pretty much. Miguel is going to have te rewrite everything.
