RazorEngine string layouts and sections?

Question

I use razor engine like this:

public class EmailService : IService
{
    private readonly ITemplateService templateService;

    public EmailService(ITemplat

Turns out after some digging that layouts are supported, we just have to declare them with _Layout instead of Layout

As for the embedded resource issue, I implemented the following ITemplateResolver

using System;
using System.IO;
using System.Reflection;
using Bruttissimo.Common;
using RazorEngine.Templating;

namespace Website.Extensions.RazorEngine
{
    /// 

    /// Resolves templates embedded as resources in a target assembly.
    /// 
    public class EmbeddedTemplateResolver : ITemplateResolver
    {
        private readonly Assembly assembly;
        private readonly Type type;
        private readonly string templateNamespace;

        /// 

        /// Specify an assembly and the template namespace manually.
        /// 
        /// The assembly where the templates are embedded.
        /// 
        public EmbeddedTemplateResolver(Assembly assembly, string templateNamespace)
        {
            if (assembly == null)
            {
                throw new ArgumentNullException("assembly");
            }
            if (templateNamespace == null)
            {
                throw new ArgumentNullException("templateNamespace");
            }
            this.assembly = assembly;
            this.templateNamespace = templateNamespace;
        }

        /// 

        /// Uses a type reference to resolve the assembly and namespace where the template resources are embedded.
        /// 
        /// The type whose namespace is used to scope the manifest resource name.
        public EmbeddedTemplateResolver(Type type)
        {
            if (type == null)
            {
                throw new ArgumentNullException("type");
            }
            this.assembly = Assembly.GetAssembly(type);
            this.type = type;
        }

        public string Resolve(string name)
        {
            if (name == null)
            {
                throw new ArgumentNullException("name");
            }
            Stream stream;
            if (templateNamespace == null)
            {
                stream = assembly.GetManifestResourceStream(type, "{0}.cshtml".FormatWith(name));
            }
            else
            {
                stream = assembly.GetManifestResourceStream("{0}.{1}.cshtml".FormatWith(templateNamespace, name));
            }
            if (stream == null)
            {
                throw new ArgumentException("EmbeddedResourceNotFound");
            }
            string template = stream.ReadFully();
            return template;
        }
    }
}

Then you just wire it like this:

    internal static ITemplateService InstanceTemplateService()
    {
        TemplateServiceConfiguration configuration = new TemplateServiceConfiguration
        {
            Resolver = new EmbeddedTemplateResolver(typeof(EmailTemplate))
        };
        ITemplateService service = new TemplateService(configuration);
        return service;
    }

The type you pass is just for referencing the assembly and namespace where the resources are embedded.

namespace Website.Domain.Logic.Email.Template
{
    /// 

    /// The purpose of this class is to expose the namespace of razor engine templates in order to
    /// avoid having to hard-code it when retrieving the templates embedded as resources.
    /// 
    public sealed class EmailTemplate
    {
    }
}

One last thing, in order to have the templates resolved with our resolver we have to resolve them like this:

ITemplate template = templateService.Resolve(templateName, model);
string body = template.Run();
return body;

.Run is just a simple extension method since I can't find any use for a ViewBag.

public static class ITemplateExtensions
{
    public static string Run(this ITemplate template)
    {
        ExecuteContext context = new ExecuteContext();
        string result = template.Run(context);
        return result;
    }
}

UPDATE

Here are the missing extensions

    public static string FormatWith(this string text, params object[] args)
    {
        return string.Format(text, args);
    }

    public static string ReadFully(this Stream stream)
    {
        using (StreamReader reader = new StreamReader(stream))
        {
            return reader.ReadToEnd();
        }
    }
