None, only the ones that are specific to SQL Server running @ Azure:

• http://msdn.microsoft.com/en-us/library/ee336245.aspx

Those ones that are related to schema (requirement to have clustered indexes @ every table, etc.) are enforced automatically.

Btw, see http://sqlazuremw.codeplex.com/releases/view/32334 - there is NotSupportedByAzureFile.Config in application archive, that describes most of differences related to SQL.

I'm going to publish v4.2 RC this weekend, so if you don't want to play with our source code repository to get the latest build, I recommend you to wait for few days.

I just noticed Dmitri has made a mistake: there is no "azure://" prodocol, you must use "sqlserver://" there, see:

We didn't create a special protocol, since Azure SQL Database reports it is SQL Server of version 10, so we decided to create a provider version for it aware of its limitations (provider version = a special subset of SQL DOM provider classes overriding logic of their bases, it's a standard approach to dealing with RDBMS versions in SQL DOM).
