Intellisense not working
A: In Visual Studio 2010, intellisense has a defined limit on the file size. If the file gets too large, intellisense will no longer work on that file but the file will continue to build in the solution. Also, a message will appear in the Error List window explaing how to resolve this. The message will state "The script exceeds the Transact-SQL IntelliSense maximum script size setting. You can change the setting on the Text Editor/Transact-SQL/IntelliSense Page in the Tools/Options menu."
