Entity Framework apply migrations at runtime

i'm creating a C# WinForms application which uses Entity Framework Code First and it is set to create the database if it doesn't exists.

Since the app is not distributed with a database, it creates it when it's needed, so i need to find a way to detect which migrations need to be applied for each case when i release a new version of the app.

How can i detect and apply needed migrations at runtime?

try this Initializer:System.Data.Entity.MigrateDatabaseToLatestVersion,it will update your database（no delete db,no delete data）,just update entity changed.

Database.SetInitializer(new MigrateDatabaseToLatestVersion<T, DbMigrationsConfiguration<T>>());
        try
        {
            using (var ctx = new T())
            {
                ctx.Database.Initialize(true);
            }
        }
        catch (Exception e)
        {
        }
