The Visual Studio Ranger team has recently released five detailed guides in advance of the VS2010 and TFS2010 releases.

• Visual Studio 2010 Quick Reference Guidance: consists of compact cheat sheets for Team Foundation Server (TFS) 2010 and Visual Studio (VS) 2010, addressing the core problem of teams in the field who are unaware of Visual Studio and Team Foundation Server capabilities or have little time to invest in detailed education.
• Visual Studio 2010 TFS Upgrade Guide:  covers scenarios which may be encountered during and after the upgrade process. It provides examples of most common and potential issues. It covers scenarios related to general Upgrade Process, Work Item Templates, Reports, and Enterprise TFS Management (ETM).
• Visual Studio Team Foundation Server Branching Guide 2010: Branching and merging of software is a very large topic. It is an area where there is a lot of maturity in the software industry. This Ranger solution focuses on applied and practical examples of branching that you can use right now. The 2010 release includes discussions around branching concepts and strategies but also focuses on practical hands-on labs.
• Visual Studio 2010 Team Foundation Server Requirements Management Guidance: Requirements Engineering (RE) using Team Foundation Server. We provide formalized Microsoft field experience in the form of recommended procedures and processes, Visual Studio Team System and Team Foundation Server configurations, and skill development references for the Requirements Engineering discipline of your application lifecycle.
• Visual Studio 2010 and Team Foundation Server 2010 VM Factory: prescriptive guidance around the virtualization of the Visual Studio 2010 and guidance for full automation of the creation of virtual machines. We help users with the installation and configuration of virtualized environments with least effort and maximum automation.

Each one of these projects was chosen in part due to field and customer demand and were directly informed by practical experience from MCS consultants and MVPs involved in the projects. As such, they’re field tested and customer ready materials available in advance of the product release. 

There’s a lot of good information here in preparation of VS 2010. I highly recommend you look through it.

Excelsior!
