Hi,
I have created a database under the SQL Server Management Studio, but when I tried to open this database from Visual Studio C# or Visual Web Developer I get a permission error saying
"This file is in use. Enter a new file name or close the file that is open in another program"
I am sure that i closed the SQL Server Management Studio and its instances.
What am I missing here?
Second question, is there a way to work with both applications Visual C# for instance and the SQL Management Studio on the same database? Since the studio offers more DB features
Thank you

SSMS (sql server mgmt studio) is only an IDE to the Sql Server engine. That engine, which runs as a Windows Service, locks the database.
To detach a database, you have to go into SSMS, connect to the database server, then right-click the database to expose functions. The right-click is the power of generating sql statements, too (although not complex ones).
For complex sql generators, you'll have to consider commercial software (a Bing or Google search should suffice).
To use 2 IDE's to interact with your database, you would use SSMS as you currently do... but DO NOT DETACH the database. In VS you would connect to the database server engine (local)\SQLEXPRESS or whatever its name, then interact that way.
Hi nasserd,

An MDF file is a MS SQL Server database file; the file is in use when SQL Server service is running (and locking) the file.
You would have to detach the file from SQL Server if you want to manage the database separately.
Optimally, you can access some functions through VS when you connect to the database itself (through its existing SQL Server instance).
