With VSTS 2010 comes TFS "Basic"
TFS is a pretty large piece of software. To deploy a TFS instace will require knowledge of both TFS and the underlying infrastructure (SQL Server DBMS, SQL Server Reporting Services, SQL Server Analysis Services, Windows Sharepoint Services and so on), which makes it difficult for some companies to handle. Not all team require all the TFS features so dealing with the pre-requisites can be a big deal. The licensing model and its pricing has also been a pain in some segments.
Last night Brian Harry wrote a lenghty post about the latest addition to the TFS suite. In TFS 2010 we'll have the possibility to install a subset of the full TFS, which will not require Sharpoint or Reporting services. The installer in general is much improved in TFS 2010 but in this particual case it will be a "next, next, finish"-experience, it will install the required pre-requites if needed and do the necessary configuration. This means you should have TFS up and running in less than 30 minutes! And it will run on desktop operating systems as well.
Looking forward to beta 2...
