localdb

So..I managed to almost finish all my problems.But now i deal with another one. I used this connectionstring : SqlConnection con = new SqlConnection(@"Data Source=.\SQLEXPRESS;Database=Database1.mdf"); And it throws the next error: Login failed for user ' If i remove the .mdf extension it throws the same error Now if i'll add the following to the string: Integrated Security = true It throws this: Cannot open database "Database1.mdf" requested by the login. The login failed. Login failed for user 'rBcollo-PC\rBcollo'. P.S for Integrated Security = false it throws the "Login failed for user'"

I created a brand new Web API project, created a simple Code First model (one class with an id and the dbcontext object, and that's it), and ran Enable-Migrations in the package manager console. I noticed that it creates the database in SQLEXPRESS rather than LocalDB, despite the DefaultConnection string pointing to (LocalDB) in the Web.config file. This causes subsequent queries to fail, claiming that the database hasn't been initialized. How do I get the Enable-Migrations command in VS 2012 to point to LocalDB rather than SQLExpress? I've tried installing SQL Management Studio 2012 Express

Is LocalDB supported by Visual Studio 2010 in Entity Framework 5, on .NET 4.0? Or am I doing it wrong? I'm getting a "The network path can't be found" issue when instantiating my model container with a connection string for LocalDB. Here's the connection string: var connectionString = "metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SqlClient;provider connection string=\"data source=(localdb)\v11.0;initial catalog=fablelane_com_db;integrated security=SSPI;multipleactiveresultsets=True;App=EntityFramework\""; Edit 1 I'm receiving the following error when

I am getting a "keyword not supported error" when I try to connect to a LocalDB database using ObjectContext. This is my connection string: <add name="connStr" providerName="System.Data.SqlClient" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=proj1db;Integrated Security=True" /> and this is the code that tries to create an instance of the ObjectContext: var connectionString = ConfigurationManager .ConnectionStrings["connStr"] .ConnectionString; ObjectContext _context = new ObjectContext(connectionString); The last line throws System.ArgumentException: Keyword not supported:

how does one programmatically create a localdb .mdf? acceptable solutions exclude visual studio, ssms, aspnet_regsql. a naive stab at a solution might look like this: static void Main(string[] args) { using (var con = new SqlConnection(@"Integrated Security=SSPI;Data Source=(LocalDb)\v11.0;AttachDbFilename=test.mdf")) { con.Open(); using (var cmd = new SqlCommand("CREATE DATABASE test", con)) { cmd.CommandType = CommandType.Text; cmd.ExecuteNonQuery(); } } } but of course, this fails in SqlConnection.Open with the error An attempt to attach an auto-named database for file test.mdf failed.
