Open.NET — .NET Libraries Go "Open Source"
An anonymous reader writes "whurley just posted a blog about Microsoft's announcement To Make .NET Libraries available under a crippled 'Open Source' program using their new Microsoft Reference License. The post includes the official pr doc from Microsoft as well as several points about how this really isn't open source. One example: If a developer finds a bug in the code, rather than fixing it themselves and submitting a patch to the community they'll be encouraged to submit feedback via the product feedback center."
You can already see all the source of the .NET framework using Lutz Roeder's Reflection tool. I use this all the time to see how the innards of functions work when something goes screwy with .NET.

Nowhere in Microsoft's announcement do they in any way claim that they are releasing anything as open source. But hey, don't let that stop you from attacking Microsoft for not doing something they never claimed to do nor have any obligation to do.
Yes, you are right. This does not feel like "open source". You know why? Because it is not open source. Nowhere in their announcement do Microsoft claim it is open source. They even explicitly mention that it is not open source.
The original 1991 team that developed the Microsoft Foundation Classes 1.0 (to go with the first Microsoft C++ compiler, and even before the first C++ Visual Studio) was planning to go completely "closed source." It makes sense from a library point of view to close access to the implementation, and only offer the interfaces in header files. However, I was one of the folks on that team that felt that since this was the first "thin" wrapper on the C Win32 API, it was more important to show just how thin that wrapper was, and to offer visibility into the MFC implementation. It wasn't "open source" but it was "source provided as documentation." You could still build MFC on Borland's Win32-ready compiler, in fact. Since I myself was fairly experienced with Win32 but not with C++ (as was the target market), I felt this was a reasonable compromise.
Before you throw eggs at me, let me point out that I then left that group before they invented CDocument and all the ugly MFC hell that has become associated with bloat. Before CDocument, it was essentially a reasonable alternative to STL with some HWND wrappers. Afterwards, the command-routing and OLE-managing framework turned almost any MFC app into a real rats' nest of unmaintainable spaghetti. I still wrote apps in MFC, but I have less and less stomach for it, in the rare instances I must develop Win32 at all.

I was wondering how slashdot would report this story. I knew that they would give it negative spin because it's not open source, but I didn't think they would actually try to suggest that Microsoft claimed that this was open source and then bash them for not meeting that claim.
.NET libs into VS 2008, including downloading the appropriate source from Microsoft's site on demand. There are other goodies as well.
Microsoft fully acknowledges that this code is to be released under MSRL, "Microsoft Reference Licenese", which Microsoft does not claim to be an open source license (it is not one of the Ms licenses that were submitted to OSI).
But the code is still valuable as it eases debugging. This similar to Microsoft's providing the source code to ATL, MFC, and their CRT. Much of this code was already available under Rotor2, but now we get lots more code, including WinForms and WPF, and more will be rleased in the future.
And it's not just code, but Microsoft including integrated debugging of

Actually, they do mention the term open source(well, with a hyphen...In the context of saying "no, this is not open source". But hey, the blogger got a bunch of hits by suggesting otherwise, eh?
