At 778 pages, "Microsoft SharePoint Foundation Inside Out" (available on Amazon.com) is a massive base of information for users, technologists and architects crafting solutions on SPF2010. Errin O'Connor, Penelope Coventry, Michael Doyle, Troy Lanphier, Johnathan Lightfoot, and Tom Resing have delivered an encyclopedic tour of all that can be done on this platform by administrators, users, business sponsors and developers.
Chapter 2 is a great beginning for folks trying to determine if SharePoint2010 Foundation alone is right for them. There's a lot of distinctions, explanations and screen shots comparing base functions to those offered by Search Server Express, SharePoint Server Standard and Enterprise, FAST, Search Server, etc. All of which helps enable business sponsors to understand the implications of their platform decisions. There's an arsenal of end user techniques for working with lists and libraries and creating sites. However, there are also extensive sections on customizing SharePoint with Visual Studio or administering via PowerShell – not easy topics for a casual business power user!
The authors do a good job of providing clear examples of WHY a certain list or site might be used – for example, you might use a Document Workspace to organize a Disaster Recovery plan and related documents. In addition, the authors provide plenty of step-by-step instructions with plenty of helpful screenshots.
Some of the sections provide a lot more value than their title suggest. For example, there's a section on Managing Site Content that actually provides a good introduction to SharePoint information architecture and governance. As you might expect, this is valuable to users of both SharePoint Foundation as well as the various SharePoint 2010 Server platforms.
Read carefully, though. There are a few parts of this book that discuss technologies only available in the paid, SharePoint 2010 Enterprise version of the product, such as the Decomposition Tree in Performance Point Although the authors make clear that this isn't part of SPF2010, these sections out of context could be misleading. Read the whole book!
SharePoint Foundation 2010 is a "free" product. Given that price, this book becomes an essential investment to accelerate value on the platform.
