RazorEngine string layouts and sections?

Question

I use razor engine like this:

public class EmailService : IService
{
    private readonly ITemplateService templateService;

    public EmailService(ITemplat

I needed to supply my own layout as either a string or a file name. Here is how I solved this (based on this blog post)

public static class RazorEngineConfigurator
{
    public static void Configure()
    {
        var templateConfig = new TemplateServiceConfiguration
            {
                Resolver = new DelegateTemplateResolver(name =>
                    {
                        //no caching cause RazorEngine handles that itself
                        var emailsTemplatesFolder = HttpContext.Current.Server.MapPath(Properties.Settings.Default.EmailTemplatesLocation);
                        var templatePath = Path.Combine(emailsTemplatesFolder, name);
                        using (var reader = new StreamReader(templatePath)) // let it throw if doesn't exist
                        {
                            return reader.ReadToEnd();
                        }
                    })
            };
        RazorEngine.Razor.SetTemplateService(new TemplateService(templateConfig));
    }
}

Then I call RazorEngineConfigurator.Configure() in Global.asax.cs and it's ready.

The path to my templates is in Properties.Settings.Default.EmailTemplatesLocation

In my view I have this:

@{ Layout = "_layout.html";}

_layout.html is in emailsTemplatesFolder

It's a pretty standard HTML with a @RenderBody() call in the middle.

As far as I understand, RazorEngine uses the template name ("_layout.html" in this case) as a key to its cache so the delegate in my configurator is called only once per template.

I think it uses that resolver for every template name it doesn't know (yet).
