So I just started using System.Data.Sqlite with entity framework 6 (downloaded the latest System.Data.Sqlite from Nuget, version 1.0.91.0)
After some configuration and code, I found out that I can read from the database but somehow write is not working.
Here's my code:
using (var context = new InternalDbContext())
{
var demo = context.DemoEntities.Where(d => d.ID == 1).FirstOrDefault();
demo.Name = "TestTest";
context.DemoEntities.Add(new Demo { Name = "Test" });
context.SaveChanges();
}
Basically after SaveChanges, nothing was updated in the DB. However I can read fro the DB with the data I manually populated via SQlite admin tool.
Here's my DB schema:
Table name :Demo
Field: ID - Integer Primary Key AutoIncrement
Field: Name - VARCHAR(256)
Here's my classes
public class InternalDbContext : DbContext
{
public DbSet<Demo> DemoEntities { get; set; }
public InternalDbContext()
{
// Turn off the Migrations, (NOT a code first Db)
Database.SetInitializer<InternalDbContext>(null);
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
// Database does not pluralize table names
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}
}
[Table("Demo")]
public class Demo
{
public long ID { get; set; }
public string Name { get; set; }
}

Your ./bin/Debug/ folder should contain a copy of your testdb.sqlite DB. That should have the changes.

Using Entity's visual designer I have created the most basic entity possible. I want to seed some sample data to a database I created which holds the schema for this basic entity on Azure. I want to use this db in an asp.net web form but when I go to seed the init data I get an SQL timeout error.
I am aware that when using entities Database.SetInitializer the seed operation is only called when the context is used so I forced the initialization. It seems to try yet I still get the timeout. I created a basic console application and wrote a test program to load some values into the table and it worked fine so I know it is not the connection to the DB, it is something to do with the Seeding.
Here is the actual error:
A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.SqlServer.dll
An exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.SqlServer.dll but was not handled in user code
Additional information: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

I know this is an old question, but in case anyone stumbles here from Google... you need to increase your CommandTimeout to give Azure enough time to create the db.
There is an incredibly detailed StackOverlow answer explaining why here:
Timeout when setting up Entity Framework connecting to Azure
The gist of it is that you need to add a single line into your DbContext constructor:
public MyContext() : base("name=MyContext")
{
// three minute command timeout
this.Database.CommandTimeout = 180;
}
I am using Oracle 11g and Entity Framework 6 versions.

I have changed the connection string to the following and it started working:

connectionString=" Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=yourhostname)(PORT=yourportnumber))(CONNECT_DATA=(SERVICE_NAME=""servicename))); User Id=xxx;Password=xxxx;"/>
we can find these details in tnsnames.ora file.
In Db Context add the following code:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.HasDefaultSchema("yourschemaName");
modelBuilder.Configurations.Add(new EmployeeMapper());
}

Where did I go wrong ?
Name of my DB in sql server is : MoviesDB
Thanks
EDIT:
Class Movie and MovieDBContext :

{
public class Movie
{
public int ID { get; set; }
public string Title { get; set; }

[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public DateTime ReleaseDate { get; set; }
public string Genre { get; set; }
public decimal Price { get; set; }
}
public class MovieDBContext : DbContext
{
public DbSet<Movie> Movies { get; set; }
}
}
EDIT 2 :
I changed the connection string to
<add name="MovieDBContext"
connectionString="Data Source=localhost;
AttachDbFilename=|DataDirectory|\Movies.mdf;
Initial Catalog=MoviesDB;
Integrated Security=True"
providerName="System.Data.SqlClient" />

Neither one of your connection strings there are referencing MoviesDB.
One is referring to aspnet-MvcMovie-20140418101450.mdf and the other Movies.mdf.
Your context will use the connection string that matches it's name, unless you override that setting. So you should modify the MovieDBContext connection string to point to your SQL instance instead of the LocalDB
Edit
I assume that this is similar to the connection string you actually want, but you should refer to the official Microsoft Reference for other examples.
<add name="MovieDBContext" providerName="System.Data.SqlClient"
connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=MoviesDB;
Integrated Security=True"/>
Change to :
<add name="MovieDBContext"
connectionString="Data Source=localhost;
AttachDbFilename=|DataDirectory|\MoviesDB.mdf;
Initial Catalog=MoviesDB;
Integrated Security=True"
providerName="System.Data.SqlClient" />

I'm using Entity Framework 5 , MySqlConector 6.7.4.0, Visual Studio 2012. Hope you guys can help me with this!
I found the answer with the post that user2453734 pointed EF5 Getting this error message: Model compatibility cannot be checked because the database does not contain model metadata and made a changes in the SetInitializer in Program.cs and I changed
this:
Database.SetInitializer(new DropCreateDatabaseIfModelChanges<MySqlContext>());
into this:
Database.SetInitializer<MySqlContext>(new DropCreateDatabaseIfModelChanges<MySqlContext>());
now it works!

// This method will be called after migrating to the latest version.
// You can use the DbSet<T>.AddOrUpdate() helper extension method

// new Person { FullName = "Brice Lambson" },
// new Person { FullName = "Rowan Miller" }

I read that SimpleMembershipProvider got 'replaced' with Identity. Not sure if that is related to this error. But if anyone knows a tutorial how to do the migration, I'd love to have a link of that.
Also the database layer is a class lib project. There is no MVC installed in there.
Try adding this to your web.config under runtime section:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>
And System.Web.Helpers should be referenced from your project as well
