Today I’ll be reviewing the SharePoint SDK’s. I’m not saying they are bad, but I’ve never found any good overview about ‘em. And I guess such an overview can be usefull, especially for people starting with SharePoint.

Before we begin, let me explain what a SDK is. A SDK is a Software Development Kit. It’s a set of resources designed to help understanding a specific technology. Sometimes a SDK is necessary to allow development with such a technology. (I’m thinking about the Java SDK) So, what are those resources? Well, it depends. They can include a lot of things. But most of the time, you’ll find documentation (CHM’s and the likes), samples, tools, templates, … you name it. Really usefull stuff.

SharePoint SDK’s come in different flavours. There is the online MSDN section with all the documentation, together with links to seperate downloadable resources. Or you can directly download the SDK. This download will include the documentation, samples, etc, but is suited for offline use, as an internet connection is not required once installed.

So what are the SharePoint SDK’s? First off, there is the Windows SharePoint Services 3.0 SDK. This SDK will only cover WSS related topics. And although it’s quite usefull, the offline installer includes only a couple of files, more specifically: the actual WSS 3.0 reference and a compilation of technical articles. Both can also be found on the online version.
The Microsoft Office SharePoint Server 2007 SDK is much more interesting. It includes both WSS files, and adds much more reference on the MOSS-only technologies. Also, it features some nice samples with source code. This gives us the opportunity to catch a glimpse at how the guys at Microsoft are using SharePoint, which is quite nice if you’re starting off with SharePoint and have no idea how to begin development. The MOSS 2007 SDK also includes the Enterprise Content Management Start Kit (ECM Starter Kit). This starter kit gives some in-depth information on the new ECM features and platform in Office SharePoint Server 2007. Moreover the starter kit is the collection of some white papers and code samples.

Next is a handy overview for the SDK’s:

In short, the MOSS SDK completely covers the WSS SDK. And even if you don’t have MOSS, the MOSS SDK is still very interesting and worth the download, as the samples give a great in-depth look at coding for SharePoint. ’till next time!
