Databases for Windows RT

Question

Does anybody know if Windows RT will have some form of SQL Express available? Hoping for something C# friendly rather than C++.

Answer 1

SQLite seems to be the most common option for WinRT apps. As you can see here they made WinRT support the key feature of 3.7.13 release. I'm not too familiar with SQLite, but I think it could be (easily?) used from C# as well.

It seems that some people were successfully building SQLite for ARM processors, see here.

Given that ADO.NET and ODBC are not allowed in Windows Store apps, even if SQL Server Express could run on ARM you wouldn't be able to connect to it. It is safe to assume SQL Server Express and SQL Server Compact are not going to be available for Windows Store apps anytime soon, if ever.
