Does Winforms support Code-First Entity Framework. I know ASP.net MVC support it, but how about Winforms?

I create connection string in app.config:

<connectionStrings>
    <add name ="Transaction" connectionString="DataSource=|DataDirectory|Transaction.sdf" providerName="System.Data.SqlServerCe.4.0"/>
  </connectionStrings>

I also create Transaction class with all the fields, and Transaction DbContext, but when I compile, it does not create the sdf file automatically.

Thank you.

UPDATE I added this two lines, but is still not working:

Database.DefaultConnectionFactory = new SqlCeConnectionFactory("System.Data.SqlServerCe.4.0");
            Database.SetInitializer(new DropCreateDatabaseIfModelChanges<EmvTransactions>());

It gives me this error:

  • You need to call an Initialize and install a DropDatabaseifChanged thing. @Giedrius - normally from App_Start() in MVC. Commented Jul 25, 2012 at 14:10

  • Then you need to call it somewhere else. I was responding to an older comment. Commented Jul 25, 2012 at 14:25
