Breaking news: Microsoft is following through on its promise earlier this year to open-source part of the .NET framework. TuxRadar and several other sources are confirming that within the next day or so, portions of the .NET Micro framework will be released under the Apache 2.0 license. Micro is a small chunk of .NET, but one that runs on ARM processors, which makes it of great interest to embedded software developers.

Now, this certainly isn’t all of .NET, nor even all of .NET Micro. No one seriously expected any of that. However, Microsoft’s willingness to send software that was previously highly proprietary into the open-source world is a fascinating sign of the times. Many of us are waiting with bated breath to hear how this news affects Mono, which is undoubtedly its main target. My guess is “business as usual, full steam ahead”—those folks have guts.
