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."

Maybe I'm biased - ok, definitely I'm biased - but this just doesnt feel like "open source" to me so much as "beta-testing with a peek at the code" or, to be blunt, "do our debugging for us."

Re:Could be worse

[moore.dustin (942289)]

So what? If they want you to do the debugging for them via this method then it is up to us, the users, to satisfy that. If you do not want a part of it then do not participate. It is as simple as that. If there are people out there that are willing to look and submit bugs then the program is a success to Microsoft and that is all that matters here, how it helps Microsoft. Remember though, that is not a bad thing, it is just business.

Fair enough, but Microsoft is trying to get street cred through a disingenuous use of the term "open source".

[JebusIsLord (566856)]

If you can see the code, it's visible source. The word "open" has many different connotations. Open to view? Open to change? Open to redistribute? The open source community almost always assumes the latter two definitions, so Microsoft has done well by avoiding this loaded terminology. As you can see, the author of the article puts the words "open source" in Microsoft's mouth anyhow, because they knew it would cause controversy where there otherwise isn't any.

The biggest issues I have seen with the transition to .net are in the richtextbox, the printing model and the IDE itself.

Try adding an RTF box onto a form and messing with a selection (for instance setting it to bold), the old method would allow the other font attributes to remain, now you change the font styling for the entire selection: bold italic font size etc.
Without calling back to the COM interop or recursing each character on a hidden control you are screwed.

Printing is geared towards the developer

Maybe he's talking about the IDE. I've run into lots of junk that hasn't been fixed for years. Things like .lic files becoming corrupted, loosing the ability to type non-word characters, source safe integration breaking, files in the .Net temporary directory getting locked, and projects loosing the ability to load DLLs.

Yes SCO lost, but can you afford several million in legal fees to exonerate yourself? Especially since Microsoft has already been making noise about all the patent violations already in Linux? They want a fight that they can win against Linux. Since SCO has flamed out, they will be more careful the second time; to wit, they will make sure there really is some code that at least looks like theirs before they file suit.

So, in proper /. format;

2) Kid then goes and implements something similar in Mono or elsewhere in Linux.
3) Sic the lawyers on the kid, terrorizing said kid into admitting he copied the secret code.
4) Wave around headlines "Linux coder admits copying secret MS code!"

The reflector re-generates source code based on the IL. But there's no guarantee that its the SAME source code.

But you're always going to lose some information content when compiling down to IL.

No offense intended, but I'm not sure how a post like this got modded so far up. Are we passing out tinfoil hats at the door now? (I know, I know. I must be new here.)

Let's take as a given that Microsoft would like all developers to be using their technologies. In their perfect happy world, every developer is using Visual Studio as their IDE, their language of choice is a .NET language, everyone's writing apps to run on Windows, etc. Microsoft all over the place.

In pursuit of that goal, is it more logical that they would make this move to:

A) Allow .NET devs to see/debug through the .NET libraries, making developing using their stuff more attractive to some subset of the developer community, or

B) Begin an intricate long-ranging litigation scheme against something like Mono, that even fewer developers than the subset in (A) know much about, that in no way is currently posing any kind of threat to their dominance (such as it is), on the off chance it might bear some kind of fruit years down the line?

Shit, Bond villains don't even bust out plans like the scenario you've concocted.

Re:IT a Trap! (Step 1 to kill Mono)

[Mongoose Disciple (722373)]

Out of curiosity, how much work have you done with Java and C#?

C# is to Java as Java is to C++ as C++ is to C on to infinity. To say that C# is just a copy of Java is about as much true and about as much false as saying Java is just a copy of C++. It is, and it isn't.

In each case you have a "new" language created based strongly on an old one, benefiting from the "mistakes" of the previous language.

The tricky part is, what's a mistake in the design of a language varies depending on your perspective and what you're trying to do it with -- and so the "evolved" language ends up better for some tasks and worse for others. Java addresses a ton of things that C++ doesn't do well (or require a much more seasoned C++ developer to do well), at the cost of becoming unsuitable (or at least, less suitable) for some uses, such as embedded programming or high-end game programming.

C# is that same kind of quasi-evolution from Java. It makes some things a lot easier to get right, but at a cost of giving up some of the things that are good about Java. The key here is that the differences between the two aren't as much in the base language's syntax as in the core frameworks/libraries that are built around them. That's what makes the chance to see more of what makes those libraries tick and why they made the design decisions they did interesting.

Wise move by MS

[MtlDty (711230)]

When .NET was announced as a platform independent language, I always struggled to imagine Microsoft developing the framework on anything other than Windows. Can you imagine Microsoft developing class libraries for Linux, or Apple Macs? Surely the world would end.

So this move is a fairly wise one by MS. There's now a chance that the .NET framework will be developed for other platforms. And once that happens MS can help nuture a happy little band of developers, all sucking up MSDN licenced tools.

So they encourage you to report things to them rather than distributing a patch yourself. So what?

Instead they became just another business, later honorably defending (their contributions to) the Linux source code against the wretched SCO. Their interests have become more aligned with that of their customers.

I think Microsoft has less wiggle-room to remain viable than IBM did when they lost total domination over their market (because MS's business is mainly about using restrictive copyright licensing to make sure they're the only ones controlling the software on PCs, which quite different from what IBM's business is) but something similar is happening, however slowly and painfully.

Microsoft knows, to some degree, that in order to remain relevant it must give people access to the guts of its software. The software market has become far too complex for the ancient ways of floppies-in-a-box style business to work. However, as their Open.NET idea shows, they're still trying to keep as much control as possible, for as long as possible...

Just like MFC

[Speare (84249)]

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.

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 .NET libs into VS 2008, including downloading the appropriate source from Microsoft's site on demand. There are other goodies as well.

It does introduce a big problem, though. Suppose someone's seen Microsoft's code, and in code they've written there's a stretch that's suspiciously similar to Microsoft's code. How does one go about proving that they didn't copy that code from Microsoft's in violation of the license? Access may be great for the programmer themselves, but if I'm not them and I'm using their code I suddenly acquired a big headache. And for me this isn't a theoretical excercise, I've been caught up in a lawsuit about exactly that sort of illicit propagation of code. I'd have to recommend not employing anyone for .NET work who's agreed to that license, and not using any .NET code created or touched by anyone who has, unless and until we've gotten our own license covering the Microsoft code in question. Anything else leaves too many legal question marks that're too easily avoided by just not tempting fate.

Being able to see the source means that you can take the present tool kit and work around any bugs in a deliberate manner. Whereas without the ability to see the code you have to hope that the bug is what you think it is.
