Changes to Support Schema Foldering, And Nullable EF Core Project

Changes to Support Schema Foldering, And Nullable EF Core Project Using propertyTransformer: (epi) => new EntityFrameworkCore.Scaffolding.Handlebars.EntityPropertyInfo(epi.PropertyType + (epi.PropertyIsNullable == true && !epi.PropertyType.Contains("?") ? "?" :"") , epi.PropertyName, epi.PropertyIsNullable)

@tonysneed Any feedback?

[tonysneed]

@johngold-onshift The way I think we want to approach adding support for nullable reference types is to add an EnableNullableReferenceTypes property to ReverseEngineerOptions so that you can set it to true in ConfigureDesignTimeServices when calling services.AddHandlebarsScaffolding.

public void ConfigureDesignTimeServices(IServiceCollection services)
{
    services.AddHandlebarsScaffolding(options =>
    {
        options.EnableNullableReferenceTypes = true;
    });
}

Then in HbsCSharpEntityTypeGenerator.GenerateProperties check property.IsNullable to add a '?' to properties that are nullable in the database.

Metadata will need to be added, so that the Properties.hbs template can be modified to set defaults for non-nullable properties and generate output that uses the null forgiving operator.

public partial class Customer
{
    public string CompanyName { get; set; } = default!;
}

Would you be able to create a new PR that takes this approach?

[tonysneed]

For schema foldering support, would you create another issue and a separate PR? Thanks!

@JohnGoldInc Do you plan to open another PR to implement the approach I suggested?

[johngold-onshift]

Yes, just got distracted today :)

@tonysneed For EnableNullableReferenceTypes ; do you want me to check in changes to sample project ? (where I am testing it)

[tonysneed]

Yes I think that is a good idea to check in changes to the sample project. That way, I can also run it on my side to see if I get the same behavior.

[JohnGoldInc]

@tonysneed I deleted CodeTemplates folder to let it regenerate; I see it would want to remove things like: // Comment // My Handlebars Block Helper {{my-helper}}

I assume you would want me to put that back?

[tonysneed]

Oh yes, don't delete the templates. Better if you could just update them.
