Equivalent to ObjectContext.CreateDatabaseScript

This is one of my favorite features of the EF Power Tools, and I think we should have similar functionality in EF Core.

My proposal is an db.Database.GenerateCreateScript() extension method. Here’s the implementation. 😉

public static string GenerateCreateScript(this DatabaseFacade database)
{
    var model = database.GetService<IModel>();
    var differ = database.GetService<IMigrationsModelDiffer>();
    var generator = database.GetService<IMigrationsSqlGenerator>();
    var sql = database.GetService<ISqlGenerationHelper>();

    var operations = differ.GetDifferences(null, model);
    var commands = generator.Generate(operations, model);

    var builder = new StringBuilder();
    foreach (var command in commands)
    {
        builder
            .Append(command.CommandText)
            .AppendLine(sql.BatchTerminator);
    }

    return builder.ToString();
}

I will try to get this added to EF Core Power Tools https://github.com/ErikEJ/SqlCeToolbox/issues/521

I suppose I was thinking the GenerateScript method, but it doesn’t look like much can be reused there.
