  • I downloaded a Sample SignalR Progress Bar solution.
  • It was working perfectly.
  • Added a System.IO.File.Copy(source, destination, true); line as below:
public JsonResult LongRunningProcess()
{
    string directory = Server.MapPath("~/bin/") + @"\";

    string source = directory + @"Templates\Template.xlsx";
    string destination = directory + @"Spreadsheets\output file.xlsx";
    System.IO.File.Copy(source, destination, true);

    for (int i = 0; i <= 50; i++)
    {
        Thread.Sleep(500);
        Functions.SendProgress("Process in progress...", i , 50);
    }

    return Json("", JsonRequestBehavior.AllowGet);
}
  • Now, anytime it hits this line, a WebSocketException is thrown.

If you look at these lines:

string directory = Server.MapPath("~/bin/") + @"\";

string source = directory + @"Templates\Template.xlsx";
string destination = directory + @"Spreadsheets\output file.xlsx";
System.IO.File.Copy(source, destination, true);

you will know that I was trying to work with bin folder. Every time you make a change in bin folder, IIS recycles your application domain and as a result, SignalR's connect will be reset.

Solution:
Avoid making any changes to bin folder. I transferred Templates folder to root folder (changed code to Server.MapPath("~/"))

Hope it helps.
