As you probably know, VS2010 ships March 22nd 2010, but there is no need to wait until then.  Beta2 has been out for a while and we encourage you to use it in earnest now.  We provide 'limited support' for production application development.

 

Jeff Beehler blogged about the meaning of "limited support", but here is the definition again:

  • We are committed to providing a smooth upgrade path from Beta 2 to the final release (“RTM”) of Visual Studio 2010 and the .NET Framework 4. For Team Foundation Server, this means moving data from Team Foundation Server 2008 to Team Foundation Server 2010 Beta 2 and then eventually to Team Foundation Server 2010 RTM. Most importantly this means source code, work items, tests, builds and the warehouse.
  • We give you permission to use Beta 2 to create applications using runtimes which are “go live.” For example, the .NET Framework 4 is “go live” for beta2 and you can create applications both for internal use and external use. See the license terms for more details, including pre-release notifications and other details for distribution.
  • Our Support team is staffed to help support Beta 2 if you encounter problems. If you plan to use Beta 2 for “go live” please send email to vsgolive@microsoft.com so that we can register you for beta level support.
  • Another option for requesting assistance is to visit MSDN Forums. The MSDN Forums are frequented by Microsoft MVP’s and members of the product group, and are a great place to search for issues submitted by others which might match problems you encounter.
  • You should take adequate measures to back up and protect your data prior to upgrading to Beta 2. You should also have an ongoing data backup and protection plan in place during your use of Beta 2.
