connection-string

I'm using .NET 4.0, MVC3, and EF5 with code first. My solution is split up into three projects, with the dependencies as indicated: Project.Web -> Project.BLL -> Project.DAL The Project.DAL layer contains my entity framework data context class and all my entities, but my startup project is Project.Web, so it contains my Web.config, connection strings, and the actual SQL compact database. I'm trying to enable migrations so I can add a new table to my EF model without wiping the existing data. However, when I run "Enable-Migrations", I get No context type was found in the assembly 'Project.Web'.

We recently switched to Entity Framework data migrations and I am working on some build automation scripts for our MVC app. I can successfully run the migrations from our build server using the migrate.exe tool in 4.3 if I have a Web.config to point it at. The command looks something like: ProjectName\packages\EntityFramework.4.3.1\tools\migrate.exe MyAssembly /startupdirectory:ProjectName\bin\Debug /startupconfigurationfile:ProjectName\Web.config /verbose However, for various reasons I would like to avoid using the Web.config and just pass in the correct connection string at the time of the

I am trying to an SQL Express instance on the same network, authenticating with my domain user. It works just fine with Windows Authentication in SSMS. I verified that I can use the MyDB database, including editing tables. However, when I try the following connection string: Server=ipaddress\SQLExpress; Database=MyDB; Integrated Security=SSPI; I get back an error: Cannot open database "MyDB" requested by the login. The login failed. Login failed for user 'ROMANIA\MONSTER2$' The problem is that MONSTER2 is the name of my computer, not my username. (ROMANIA is the domain.) What am I doing wrong?

So, I created my entity model in a separate class library. I had to add the connection string to the app.config file of that class library. Then I added a ref for that project in my web application. I added the same connection string in the web.config of my web application thinking this is where Entity Framework will be reading the connection string from. Everything was fine up until I deployed my web app. When I deployed I change the connection string in the web.config (not app.config of the class library) and I started getting errors. After doing some research I found out that the connection

public class Context : DbContext { public Context(string connString) : base(connString) { Database.SetInitializer(new MyContextInitializer()); } //... Need to pass a connection string to the context constructor. How should the string look like, for example, for SQL Compact? Tried this, but no success: Context db = new Context("Provider=System.Data.SqlServerCe.4.0;Data Source=D:\\Context.sdf"); Edit: If I try this string: "Data Source=D:\\Context.sdf" System.Data.ProviderIncompatibleException was unhandled Message=An error occurred while getting provider information from the database.
