Object reference not set to an instance of an object in MVC

This is the common error in MVC when you navigate to a View, “Object reference not set to an instance of an object”.

 

When you right click go to the controller then you will see the code like below.

publicActionResult Index()

{

  return View();

}

 

The code above basically has nothing to return. You will then ask “why there is no error from Visual Studio?” Well, this is because syntax is perfectly legal. The actual fact is you need data to render.

 

In this sample I have an Entity Framework called FuseGenDBEntities so I will modify the code as below.

 

publicActionResult Index()

{

  FuseGenDBEntities context = newFuseGenDBEntities();

 

  var result = from r in context.Products select r;

 

  return View(result);

}

 

The error should gone if you test run it again.
