I plan on installing Multiple Instances of MS SQL EXPRESS on my Development Server.
I am hoping this will let me get around the limitations of SQL EXPRESS:
If you have an MSDN subscription then you can install the Development version and I don't believe that has any restrictions...of course it's for development purposes only.
You can purchase SQL Server Developer Edition from Microsoft at this link...it's $50
As of 2016 (?) SQL Server Developer Edition is Free, downloadable at microsoft.com/sqlserver.
