I did a presentation on web services and WCF recently for a crowd that consisted mainly of Java developers. Some admitted they were downright in awe of just how forward-thinking Microsoft is with WS-* support and were even more impressed at the types of demos I was able to conjure up in front of them with little or no code. However, one guy stated he was not all that impressed with .NET, and said it would be more impressive if .NET were to become an open source project “just like Java”. We spent some time discussing the Shared Source CLI and how that has been available from the inception of .NET. Not sure if that suddenly made him a fan of .NET, but it certainly did change the tone of the discussion from Microsoft-as-follower to Microsoft-as-innovator :)
Several days later, a colleague of mine, Rob Cameron, pinged me about shared source projects at Microsoft as part of a discussion he was having with another customer. I knew that there were projects like WiX that splashed headlines, and in a company this big you know there are bound to be a few more efforts as well. I did a little digging, and I was kind of surprised at the number of efforts I turned up.
Below I list a lot of links to various projects and initiatives around Microsoft involving shared source. There might be more, and various members of Microsoft might be participating in other shared source projects, but the list below consists of the projects I could definitively link to Microsoft. If you know of other initiatives or Microsoft participation, please leave a comment!
Microsoft Shared Source Home Page

Microsoft XSD Inference 1.0
The Microsoft XSD Inference utility is used to create an XML Schema definition language (XSD) schema from an XML instance document. When provided with wellformed XML file, the utility generates an XSD that can be used to validate that XML file. You can also refine the XSD generated by providing the tool more wellformed XML files. The download contains the core library, simple command line utility and the source code.
Office 2003 XML Reference Schemas
Microsoft offers open and royalty-free documentation and licenses for the Microsoft Office 2003 XML Reference Schemas.

This is one of those areas that software developers like to gloss over… I got it for free, so I can use it, right? There are different types of licenses associated with various bits of code (some only let you read code, while others let you modify and even sell your modifications). You can find out more about the licenses at:
Here is a quick snapshot.
Microsoft Permissive License (Ms-PL) - The Ms-PL is the least restrictive of the Microsoft source code licenses. It allows you to view, modify, and redistribute the source code for either commercial or non-commercial purposes. Under the Ms-PL, you may change the source code and share it with others. You may also charge a licensing fee for your modified work if you wish. This license is most commonly used for developer tools, applications, and components.
Microsoft Community License (Ms-CL) - The Ms-CL is a license that is best used for collaborative development projects. This type of license is commonly referred to as a reciprocal source code license and carries specific requirements if you choose to combine Ms-CL code with your own code. The Ms-CL allows for both non-commercial and commercial modification and redistribution of licensed software and carries a per-file reciprocal term.
Microsoft Reference License (Ms-RL) - The Ms-RL is a reference-only license that allows licensees to view source code in order to gain a deeper understanding of the inner workings of a Microsoft technology. It does not allow for modification or redistribution. This license is used primarily for technologies such as development libraries.
I was really impressed to see this amount of activity in shared source, as it has not been a focus area of mine at all over the past several years. I am certain that this is only the beginning.
