Extremely easy way to create Pdf files from Asp.net MVC.

Usage:

public ActionResult PrintIndex()
{
    return new ActionAsPdf("Index", new { name = "Giorgio" }) { FileName = "Test.pdf" };
}
public ActionResult Index(string name) 
{ 
    ViewBag.Message = string.Format("Hello {0} to ASP.NET MVC!", name); 
    return View(); 
}

ViewAsPdf now available. It enables you to render a view as pdf in just one move, thanks to scoorf

public ActionResult TestViewWithModel(string id)
{
    var model = new TestViewModel {DocTitle = id, DocContent = "This is a test"};
    return new ViewAsPdf(model);
}

Also available a RouteAsPdf, UrlAsPdf and ViewAsPdf ActionResult.

It generates Pdf also from authorized actions (web forms authentication).

I create a simple converter based in hkhtmltopdf project, look more in:

 

 

Enjoy!

Simple, reference that:

 

using Microsoft.AspNet.Identity;

 

After you can see two extensions:

//get User Id
var CurrentUserId = User.Identity.GetUserId()
//get UserName
var CurrentUserName = User.Identity.GetUserName()

Enjoy it!

The “Unit Test Generator” extension is available

To add directly from Visual Studio 2012/2013 IDE:

  1. Menu: Tools -> Extensions and Updates
  2. Click: Online -> Visual Studio Gallery
  3. Search for: “Unit Test Generator”

MSDN Video Demonstration

Note: MSTest in VS 2012/2013 still sucks
