    Hello everyone

    I have a MVC5 application when I run it on my localhost everything works without any errors. When I publish my app then I transfer it to Windows Server 2016 I put the files in wwwroot in the IIS folder and I link everything to create a new website in IIS. I then run the website and it works. I get my javascript code to work but when I go and run my ‘ajax’ methods I get an 404 error and in the function I cannot find my controller action so the method will work. Here is my actual error: xxx.xxx.xx x.219/Parts/DoPartBookFunc?bookval=8 404 (Not Found), Failed to load resource: the server responded with a status of 404 (Not Found)

    I been researching and trying a bunch of different things but so far no luck. Some I tried was @Url.action(“”,””), adding a ~ in front adding ../ in front making a global file and many other things. If someone knows how to fix this it would be hugely appreciated.

    $("#PartBook").on("change", function () {
                    var selectV = $(this).val();
                    var selectT = $(this).text();
                        url: '/Parts/DoPartBookFunc',
                        type: 'GET',
                        dataType: 'json',
                        data: { bookval: selectV },
                        //contentType: 'application/json; charset=utf-8',
                        success: function (data) {
                            //alert("s" + data.PartNextNumber);

    A 404 (Not Found) is pretty specific.  You did not post the Controller Actions so I assume Parts.DoPartBookFunc does not exist or the method is not decorated with an [HttpGet] attribute.

    Have you tried opening the URL in the browser?
