I think I might need to do all of the Razor imports for the custom template engine ...

private static RazorSourceDocument GetDefaultImports()
{
    using (var stream = new MemoryStream())
    using (var writer = new StreamWriter(stream, Encoding.UTF8))
    {
        writer.WriteLine("@using System");
        writer.WriteLine("@using System.Collections.Generic");
        writer.WriteLine("@using System.Linq");
        writer.WriteLine("@using System.Threading.Tasks");
        writer.WriteLine("@using Microsoft.AspNetCore.Mvc");
        writer.WriteLine("@using Microsoft.AspNetCore.Mvc.Rendering");
        writer.WriteLine("@using Microsoft.AspNetCore.Mvc.ViewFeatures");
        writer.WriteLine("@inject global::Microsoft.AspNetCore.Mvc.Rendering.IHtmlHelper<TModel> Html");
        writer.WriteLine("@inject global::Microsoft.AspNetCore.Mvc.Rendering.IJsonHelper Json");
        writer.WriteLine("@inject global::Microsoft.AspNetCore.Mvc.IViewComponentHelper Component");
        writer.WriteLine("@inject global::Microsoft.AspNetCore.Mvc.IUrlHelper Url");
        writer.WriteLine("@inject global::Microsoft.AspNetCore.Mvc.ViewFeatures.IModelExpressionProvider ModelExpressionProvider");
        writer.WriteLine("@addTagHelper Microsoft.AspNetCore.Mvc.Razor.TagHelpers.UrlResolutionTagHelper, Microsoft.AspNetCore.Mvc.Razor");
        writer.WriteLine("@addTagHelper Microsoft.AspNetCore.Mvc.Razor.TagHelpers.HeadTagHelper, Microsoft.AspNetCore.Mvc.Razor");
        writer.WriteLine("@addTagHelper Microsoft.AspNetCore.Mvc.Razor.TagHelpers.BodyTagHelper, Microsoft.AspNetCore.Mvc.Razor");
        writer.Flush();

        stream.Position = 0;
        return RazorSourceDocument.ReadFrom(stream, fileName: null, encoding: Encoding.UTF8);
    }
}

... and then specify those defaults ...

public CustomRazorTemplateEngine2(RazorEngine engine, RazorProject project) 
    : base(engine, project)
{
    Options.ImportsFileName = "_ViewImports.cshtml";
    Options.DefaultImports = GetDefaultImports();
}

However, I just moved a test app to 2.1, and it's breaking now. It looks like the new <body> Tag Helper must have a closing tag, but WebMarkupMin.Core removes that as part of its minification. Therefore, I'll probably need to escape the closing <body> tag.

I'm slammed at the moment, but I'll try to get back to this by Sunday and ping you back here. In the meantime, try to implement those defaults ☝️ and see if that works.
