While we already have the code so SP1 final will support the RTM version of SQL Server 2008, because of changes during their development, our SP1 Beta only supports the "February CTP" version of SQL Server 2008.

If you already have the SQL Server 2008 CTP installed and aren't sure if it's that CTP or not, the version number for the February CTP is 10.00.1300.13.

If you want to do a fresh install against SQL Server 2008, though, you'll need to do our "integrated install".  Abdelhamid posted the instructions in a blog entry earlier today.

The steps to perform the integrated install are easy

  1. On the server that you plan to install Application Tier on copy the RTM media (AT folder on the DVD) to a local folder say <AT RTM Folder>
  2. Extract the SP1 package to a local Folder by executing the command TFS90sp1-KB949786.exe /extract:<SP1 Folder>
  3. Run the following command to combine both RTM and SP1 to one install package: msiexec /a <AT RTM Folder>\vs_setup.msi /p <SP1 Folder>\ TFS90sp1-KB949786.msp TARGETDIR=<AT SP1 Folder>
  4. Your Integrated RTM+SP1 setup is now available in <AT SP1 Folder>. You can run setup.exe in this folder to install Team Foundation Server 2008 SP1
