Install 2 NuGet packages iTextSharp and itextsharp.xmlworker and use the following code: 

using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.tool.xml;


byte[] pdf; // result will be here

var cssText = File.ReadAllText(MapPath("~/css/test.css"));
var html = File.ReadAllText(MapPath("~/css/test.html"));

using (var memoryStream = new MemoryStream())
{
            var document = new Document(PageSize.A4, 50, 50, 60, 60);
            var writer = PdfWriter.GetInstance(document, memoryStream);
            document.Open();

            using (var cssMemoryStream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(cssText)))
            {
                using (var htmlMemoryStream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(html)))
                {
                    XMLWorkerHelper.GetInstance().ParseXHtml(writer, document, htmlMemoryStream, cssMemoryStream);
                }
            }

            document.Close();

            pdf = memoryStream.ToArray();
}

Check out Pechkin, a C# wrapper for wkhtmltopdf.

Specifically at this point in time (considering a pending pull request) I'd check out this fork that addresses a couple of bugs (particularly helpful in IIS based on my experience).

If you don't go with the fork / get other stability issues you may want to look at having some kind of "render queue" (e.g. in a database) and have a background process (e.g. Windows service) periodically run over the queue and render then store the binary content somewhere (either in database as well, or on file system). This depends entirely on your use-case though.

Alternatively the similar solution @DaveDev has comment linked to.
