Too early to say anything. IMO, it was only a few years ago that .Net felt completely dead and developers were not sure what Microsoft was going to do. This is why .Net didn't take over the Enterprise market in my opinion.

Now, that it is going to be open-source and MS is pushing it harder than it has before, it might have a good chance being used for "new projects" but I've seen MS do this before only to fall off the wagon and stop focusing on these type of stuff.

In addition, the "enterprise" market move much slower than anybody and they care about backward compatibility. It would be several years before .NET would be considered for new projects. It is in that timeframe that Microsoft needs to seriously focus on this and explain why .NET should be used instead of Java.
