ObjectContext ConnectionString Sqlite
Found it =)
if you use the EntityConnectionStringBuilder to specify the Metadataand the Provider and use the SqlConnectionStringBuilderto build the provider connection string and set the DataSource to your DB. You can connect =)
var con = new EntityConnectionStringBuilder() { Metadata = @"res://*/Db.TracModel.csdl|res://*/Db.TracModel.ssdl|res://*/Db.TracModel.msl", Provider = @"System.Data.SQLite", ProviderConnectionString = new SqlConnectionStringBuilder() { DataSource = db, }.ConnectionString, };connection = con.ConnectionString;
