Have you ever created a Database project and after some time you are not able to load it in the Visual Studio? Probably you might be getting following error:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 – Error Locating Server/Instance Specified)
The database project requires an active database connection to load at design time. Probably it uses that to compile/verify scripts. The problem here is Visual Studio is not able to connect to any such instance. Following are few solutions (these worked for me)
- Make sure the instance to which you want to connect is running and allows remote connections.
- After performing step 1, if it is still not loading then you may need to start the SQL Browser Service. Make sure it’s running.
- If the problem is still there, it has to be fixed from Visual Studio itself. Actually database project do not store to which instance it can connect. It’s a Visual Studio setting.In VS2008 go to Tool > Options > Database Tools > Design-time Validation Database > Connection Options. Specify your instance name here like “\SQLEXPRESS”
If the problem is still there post it to MSDN forums 🙂
