Unable to start debugging on a web server. Could not start ASP.NET debugging.

If you attempt to debug an ASP.NET web application and get the following error, you can Google it and find a lot of hits.  There are also numerous posts on StackOverflow for this error but interestingly none of the answers in these posts helped for me.

What worked for me was simple.

The application was being deployed in the DefaultApp pool with the following properties:

  • .NET CLR version = 4.0
  • Managed Pipeline = Integrated
  • Identity = domain/my-user-name

I changed the target application pool to one called .NET 4.5 with the following properties:

  • .NET CLR version = 4.0
  • Managed Pipeline = Integrated
  • Identity = ApplicationPoolIdentity

With this change, I was able to run the application in debug mode.

Happy coding.




The value of quality tech support from web hosting partner

Technical service is paramount in our business, especially if you, like me, do not like farting around with stuff other people do better, such as hosting web applications.  I prefer to think of my speciality as crafting and building top notch software solutions and prefer to let others who are best at providing for me the infrastructure to do just this.

This is what has provided for me over the years. I have nothing but praise about their commitment to quality infrastructure, support and service. Regardless of the time and day you are almost guaranteed to get a response from these guys in very reasonable time, in most cases under three hours.

See, I have an ASP.NET MVC transit application being prototyped.  Application is being migrated from Windows Azure because I could not find a way to host it on a relative path. And since is already hosting our family charity’s website, I naturally turned to them for help.

I signed up for a new account on Jan 18, 2015, and in 24 hours after updating my DNS settings with my domain registrar, my domain name was up and running. Next, I deployed my ASP.NET MVC application to the servers and this is when things started to get interesting.

Since the application’s database still resides in Azure, I had to add an IP white list to entry to Azure’s management portal . The folks at promptly provided the IP address list and were also very quick to correct all the misunderstandings ( and I had many) that kept coming up. We went back and forth on this several times and at one point, they were prepared to do a remote session via webex. Now, this is technical support.

After they confirmed to me that they were able to connect to my Azure database, it was just a simple matter for me to correct some minor glitches in the application and re-deploy it for it to start working correctly. If I was doing all of this by myself, there is no way the work could have been done in such a short period of time, further distracting me from the actual task of creating great software.

Nothing but good words for these guys and this is what, in my humble opinion, is a distinguishing factor amongst web hosting partners. Having these kinds of reliable partners is well worth the money, allowing one to focus on what they do best.

And no, I am not affiliated with them in any way.
