I added an mdf to my project, opened table and some data to it.
Now I tried to make a typed dataset (to attach with my datagridview to display data)
It returns error:

you do not have permission to open this file
Contact the file owner or Administrator

What is that? Who is owner?

It depends what you mean by "I added an mdf to my project" but it is not usual to include an MDF file in anything.

The problem you are having is that the file is locked and secured for exclusive use by the SQL server process. You could grant yourself permissions (or have the domain admin do this for you if you don't have priviliges to do this), but the chances are you shouldn't be trying to move the mdf file directly.

If you want to move the schema, Visual Studio professional and up has a database project. If you want to move the database you will be better off working with backup files.

Thanks a lot. By adding I mean In Solution Explorer >> Add New Items >> Service-Based Database. Then I added table in Server Explorer.
So I should use backup files if i need to distribute them with my application?
