Hello

When I try to install Sql server 2008 r2 on my windows 7 32 bit ultimate I get this error. http://www.img4up.com/up2/77005471169527712970.jpg[^]

I click continue. and after installing when I want to connect it from visual studio I get this error:

SQLException was unhandled A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL server is configured to allow remote connections.(provider:Named Pipes Provider,error:40-could not open a connection to SQL Server)

In installation wizard I saw that the instance name is not applicable.

How I can solve these problems and connect to sql server 2008 r2 from vs2010?

This is a screen shot from my sql configuration: http://www.img4up.com/up2/47950084566701531201.jpg[^]

Can you establish connection via SQL Server Management Studio to your server?

I create a database in sql server management. I can not connect it from visual studio 2010.

Check the protocols in SQL Server Configuration Manager (Configuration Tools folder in Program menu). Which ones are enabled?

shared memory and tcp/Ip are enabled. and Named pipes and VIA are disabled.

Instance name is not applicable. Is this the reason of cause error?
Why instance name is not applicable?

Are you sure you've entered any instance name? MSSQLSERVER must be as a default. Try to find some information in installation log for details.

Default Instance is for ms sql server express. visual studio is installed it. I select named instance. and enter SQLServer2K8 for instance name.

MS SQL 2008 Express has an issue with named instances. Please see this note about it
