Microsoft.VsHub.Server.HttpHostx64.exe and Microsoft.VsHub.Server.HttpHost.exe crash when you debug code in Visual Studio 2015

When you use Microsoft Visual Studio 2015, Windows repeatedly reports that one of the following applications stopped working:

• Microsoft.VsHub.Server.HttpHostx64.exe

• Microsoft.VsHub.Server.HttpHost.exe

This article contains steps to diagnose the issuse and a workaround.

This issue occurs because Microsoft.VsHub.Server.HttpHostx64.exe and Microsoft.VsHub.Server.HttpHost.exe provide services and additional information to Visual Studio through an external process when you debug code. These processes communicate over HTTP through the local host. Applications that detour network activity can cause compatibility issues that cause these processes to crash.

Applications that monitor malware and create VPNs are examples of applications that are likely to cause this issue.

To determine whether this is the problem, create a simple console program by using the following code, build the code as a 32-bit .exe program for 32-bit Windows or as a 64-bit .exe program for 64-bit Windows, and then try to run this program. If the program crashes, you have an incompatible program installed on your computer.

using System;  
using System.Net;  
  
namespace HttpListenerTest  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            Console.WriteLine("Running as {0}",Environment.GetEnvironmentVariable("PROCESSOR_ARCHITECTURE"));  
            using (HttpListener s = new HttpListener())  
            {  
                s.Prefixes.Add("http://localhost:49154/vshub/418f29b9cebf4d6bae64d16162f56832/");  
                s.Start();  
                Console.WriteLine("Server started");  
            }  
  
            Console.WriteLine("Server stopped");  
        }  
    }  
}  

To work around this issue, uninstall the software that detours network activity. Or, contact the application vendor for additional support.
