Deploying a .NET 4 app. with SQL Server 2005 on production server.

What is the compatibility level of the database that you used on the local system with SQL 2008?  If you developed it using a later compatibility version than what SQL 2005 is then you could be running into some compatibility issues even though you are not utilizing the features that come in 2008.

any error message? are you using new features of SQL 2008 in your queries?

Hi mcetlinski,
the reason is because the production server is win2003 with SQL 2005 and the development environment is windows 2008 and SQL 2008.

here's the error:

thank you,

you are using the Named Pipes protocol. Add "Network Library=DBMSSOCN" to your connection string to use the TCP/IP protocol

Hello emoreau,

Thank you for your quick answer !

It seems that we are making progress but not quite there yet:

After adding the Metwork Library string to the connection string we now get this exception:

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: TCP Provider, error: 0 - No such host is known.)

Best ...

Noël

Thank you ...

I just set the Compatibility level on the DB on my local system to SQL 2005 by running this Query:

ALTER DATABASE ``MyDB_Name
SET COMPATIBILITY_LEVEL = 90

And it runs ok, so i guess we can rule out the compatibility level issue.
