问题
I have just installed SQL Server Compact Edition 4.0 on my Windows 7 machine. (Note that I already had SQL Server Compact 3.5 SP2 on the machine).
However, in my Visual Studio 2010 project, I am unable to create a new connection to a SQL Server Compact Edition 4.0 database... i.e. - by doing the following:
- In Server Explorer, right click "Data Connections"
- "Add Connection"
- "Change Data Source" - Microsoft SQL Server Compact 4.0 not an option (only version 3.5)
How can I make Visual Studio 2010 know about my already installed copy of Microsoft SQL Server Compact 4.0?
回答1:
See
- SQL Server Compact 4.0 Tooling Support in Visual Studio 2010 SP1 and Visual Web Developer Express 2010 SP1
and
- Visual Studio 2010 Service Pack 1 with support for SQL Server Compact 4.0 released
Do you have VS2010 SP1 installed?
If not - download it from here
