Opening a pdf file directly in my browser

I would like to view a PDF file directly in my browser. I know this question is already asked but I don't found any solution that works for me.

Here is my action's controller code so far:

public ActionResult GetPdf(string fileName)
string filePath = "~/Content/files/" + fileName;
return File(filePath, "application/pdf", fileName);

Here is my view:

doc = "Mode_d'emploi.pdf";

<p>@Html.ActionLink(UserResource.DocumentationLink, "GetPdf", "General", new { fileName = doc }, null)</p>

When I mouse hover the link here is the link:

enter image description here

The problem with my code is that the pdf file is not viewed in the browser but I get a message asking me if I wand to open or save the file.

I know it is possible and my browser support it because I already test it with another website allowing me to view pdf directly in my browser.

For example, here is the link when I mouse hover a link (on another website):

enter image description here

As you can see there is a difference in the generated link. I don't know if this is useful.

Any idea how can I view my pdf directly in the browser?

Instead of returning a File, try returning a FileStreamResult

public ActionResult GetPdf(string fileName)
    var fileStream = new FileStream("~/Content/files/" + fileName, 
    var fsResult = new FileStreamResult(fileStream, "application/pdf");
    return fsResult;
