Entity Framework 4 and SQL Compact 4: How to generate database?

Question

I am developing an app with Entity Framework 4 and SQL Compact 4, using a Model First approach. I have created my EDM, and now I want to generate a SQL Compact 4.0 database

Answer 1

You can use IDatabaseInitializer and create the database in code using

if (File.Exists("Test.sdf"))
    File.Delete("Test.sdf");

string connStr = "Data Source = Test.sdf; Password = ";

SqlCeEngine engine = new SqlCeEngine(connStr);
engine.CreateDatabase();
engine.Dispose();

SqlCeConnection conn = null;

try {
    conn = new SqlCeConnection(connStr);
    conn.Open();

    SqlCeCommand cmd = conn.CreateCommand();
    cmd.CommandText = "CREATE TABLE myTable (col1 int, col2 ntext)";
    cmd.ExecuteNonQuery();

catch {
finally {
    conn.Close();
