Migrate database generated by entity framework to sqlserver

I made a application with database generated by entity framework(code first) and now I want to make my application working on other computer. I instaled sqlserver there and made all the tables in the database (I am working just with localhost database). Now I wanted to connect my database with application, I thought that all what I need to do is just change connection string. But I am not able to connect to my database.
Here is how looks my app.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
</startup>
<connectionStrings>
<add name="InzerceConnection" connectionString="Data source=VRBASPC\SQLEXPRESS;Initial Catalog=AdvertisingSystemDB;Trusted_Connection=true;MultipleActiveResultSets=true" />
<!--This is how my connection string works by default <add name="InzerceConnection" connectionString="Server=(localdb)\\MSSQLLocalDb;Database=Inzerce_Dev;Trusted_Connection=true;MultipleActiveResultSets=true" />-->
<!--<add name="InzerceConnection" connectionString="Server=localhost\SQLEXPRESS;Database=AdvertisingSystemDB;Trusted_Connection=true;MultipleActiveResultSets=true" />-->
</connectionStrings>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
<parameters>
<parameter value="mssqllocaldb" />
</parameters>
</defaultConnectionFactory>
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>
</configuration>
I tried a lot of combination of connection string, but none worked.
I am not sure how to setup my config file to connect to database.
Thank you for any advice.
Sory for my english its not my native language.

In your context override the OnConfiguring method.
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
string connstr = ConfigurationManager.ConnectionStrings["InzerceConnection"].ToString();
optionsBuilder.UseSqlServer(connstr);
}

Check in your database context.
Database context and name attributes should be the same.
For Example
public class DatabaseContext : DbContext
{
public DbSet<Content> Contents { get; set; }
public DbSet<Category> Categories { get; set; }
public DatabaseContext()
{
Database.SetInitializer(new MyInitializer());
}
}
ConnectionStrings in your app.config
<connectionStrings>
<add name="DatabaseContext" providerName="System.Data.SqlClient" connectionString="Data source=VRBASPC\SQLEXPRESS;Initial Catalog=AdvertisingSystemDB;Trusted_Connection=true;MultipleActiveResultSets=true" />
</connectionStrings>

Specifying database connection string for EntityFramework6.Npgsql - Code First

I have an issue regarding the .NET postgreSQL provider package EntityFramework6.Npgsql. I have installed the following packages: EntityFramework 6.0.0, EntityFramework6.NpgSql 3.1.1, Npgsql 3.1.0.
Currently I have just started a WPF project so I'm using a simple standard DbContext and it looks like this:
public class TimetrackerDbContext : DbContext
{
public TimetrackerDbContext()
: base("name=DbConnection")
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.HasDefaultSchema("public");
base.OnModelCreating(modelBuilder);
}
public virtual DbSet<MyEntity> MyEntities { get; set; }
}
public class MyEntity
{
public int Id { get; set; }
public string Name { get; set; }
}
Now in my App.config file I specify the connection string. I've been trying to use this connection:
<add name="DbConnection"
connectionString="User ID=xxx;Password=xxx;Host=xxx;Port=5432;Database=xxx;Pooling=true;"
providerName="System.Data.EntityClient" />
But when I run enable-migrations -contexttypename MyDbContext in the PM Console I get the following error:
Keyword not supported: 'user id'.
I tried specyfying the metadata, provider connection string but it also threw errors and it does not make much sense to use it in Code First. In case somebody it could be useful here's my whole App.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

</startup>
<entityFramework>

</parameters>
</defaultConnectionFactory>
<providers>
<!--<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />-->
<provider invariantName="Npgsql" type="Npgsql.NpgsqlServices, EntityFramework6.Npgsql" />
</providers>
</entityFramework>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

<bindingRedirect oldVersion="0.0.0.0-3.1.0.0" newVersion="3.1.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
<connectionStrings>
<add name="DbConnection"
connectionString="User ID=xxx;Password=xxx;Host=xxx;Port=5432;Database=xxx;Pooling=true;"
providerName="System.Data.EntityClient" />
</connectionStrings>
</configuration>

The providerName of your connection string System.Data.EntityClient is for Database First (edmx) type connections where the actual provider is encoded in the connectionString value.
For Code First connections, the providerName should match the invariantName from the providers section. In your case, replace
providerName="System.Data.EntityClient"
to
providerName="Npgsql"

Entity Framework To A Remote Server (Connection String)

I have installed EF Version 6.1.3 on all my projects. I then created a model class, a context class, and installed a MSSQL database on my local computer (I did not have done anything else). Everything worked just perfectly (somehow it knew about my local database).
Model class:
public class Account
{
public int Id { get; set; }
public string Name{ get; set; }
}
DataContext class:
public class MyClassDataContext: DbContext
{
public DbSet<Account> Accounts{ get; set; }
}
App.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=xxxxxx" requirePermission="false" />
</configSections>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>
</configuration>
I then tried to move it to a remote database and it doesn't work. I tried everything.
What is the right approach, to get the job done?
EDIT:
I tried this connection string and nothing happens. The app still tries to connect with the local database.
<connectionStrings>
<add name="MyClassDataContext" connectionString="Data Source=MyRemoteServer;Initial Catalog=MyRemoteCatalog;Integrated Security=true" providerName="System.Data.SqlClient"/>
</connectionStrings>
<configSections>

You need to create either make sure that your connections string's name is the fully qualified name of your context, or create an explicit default constructor for your context. Since you mentioned it in the comments, the link you provided isn't working for you because you're using code-first. Try this link instead.
Below is a fully functional console app that can demonstrate how it should work, along with the config file. This will use our local SQLServer installation, but not the SQLExpress. It should work fine for any remote database as well.
Note that in the previous app config that I had posted, I put the connection string section at the top. That is incorrect: configSections must be the first node.
namespace TestApp
{
public class Account
{
public int Id { get; set; }
public string Name { get; set; }
}
public class MyClassDataContext : DbContext
{
public DbSet<Account> Accounts { get; set; }
}
class Program
{
static void Main(string[] args)
{
using (var x = new MyClassDataContext())
{
x.Accounts.Add(new Account { Name = "Drew" });
x.SaveChanges();
var y = x.Accounts;
foreach (var s in y)
{
Console.WriteLine(s.Name);
}
}
Console.ReadKey();
}
}
}
The configuration file:
<configuration>
<configSections>

Deploy a WPF program and update the database if required

I'm creating a WPF application that uses a LocalDB instance (which is provided by the ClickOnce installer).
The program uses a database to store userdata. When the application is deployed for the very first time, I want to create a LocalDB where some data is inserted upon initialization.
When I later provide an update to the program (which may include schema changes), I do not want to lose any userdata.
I'm using EF Code-First and this is my DbContext:
public class MyContext : DbContext
{
public DbSet<Stuff> Premises { get; set; }
public DbSet<Person> Persons { get; set; }
private static MyContext _Current;
public static MyContext Current
{
get
{
if (_Current == null)
{
_Current = new MyContext();
}
return _Current;
}
}
protected MyContext()
{
//Some data to insert on the first time
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Stuff>().HasMany(p => p.Persons).WithRequired(m => m.Stuff);
}
}
App.config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
</startup>
<connectionStrings>
<add name="MyContext"
connectionString="data source=(LocalDB)\mssqllocaldb;Integrated Security=True"
providerName="System.Data.SqlClient"/>
</connectionStrings>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
<parameters>
<parameter value="mssqllocaldb" />
</parameters>
</defaultConnectionFactory>
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>
</configuration>
Am I correct in thinking that adding my development .mdf file will always overwrite the userdata when I update via ClickOnce?
How can I let EF create the schema for the first time, update when there's changes, and never lose any userdata?

EntityFramework ignore login name in connectionString

Hi iam trying to configure my first application with EF but find no way to connect to DB
this is my context
public partial class FunzionamentoContext : DbContext
{
public FunzionamentoContext()
: base("FunzionamentoContext")
{}
static FunzionamentoContext()
{
Database.SetInitializer<FunzionamentoContext>(null);
}
public DbSet<Controllo> Controllo { get; set; }
}
this is connection string (present in app.config file of DAL project since i still don't have UI project):
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<connectionStrings>
<add name="FunzionamentoContext"
providerName="System.Data.SqlClient"
connectionString="Data Source=xyzxyz; Initial Catalog=dbName;
Integrated Security=false;User ID=test;Password=test" />
</connectionStrings>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>
</configuration>
this is a simply method i make to test connection (only for search if connection is done, next i will rewrite it in a more beautyful way :D)
[Test]
public void TestTrue()
{
FunzionamentoContext fctx = new FunzionamentoContext();
Controllo c = new Controllo();
.id = 1
fctx.Controllo.Add((Controllo)c);
fctx.SaveChanges();
}
When i try to connect i see this error:
FunzIA.UnitTest.DAL.TestFixture1.TestTrue:
System.Data.Entity.Core.EntityException : The underlying provider failed on Open.
----> System.Data.SqlClient.SqlException : Cannot open database "FunzionamentoContext" requested by the login. The login failed.
Login failed for user 'DOMAIN\U123456'.
where DOMAIN\U123456 is my windows account
Why EF use my windows account and not the one wrote in connection string?

I am assuming that you have your DAL in a separate project from the project you're actually running.
Your application will use the config file from the project you're trying to run, and not the one directly related to the DAL project.
By this, I mean, if you're only using the test project (assuming it's in a different project from the DAL) then you need the connection string in the app.config of your test project.
