I have a problem in my project, I use ASP.NET MVC 5 and for a while I get this message whenever I run my project, the problem is not the visual studio installed on the machine(as in that solution) because my coworkers have the same problem when using in their machine.

I can run my application smoothly, the problem is that if this message is appearing there is something wrong and I’ve done 300 million searches and do not solve.

The message is:

Debugger not installed fix. Unable to debug type of code requested. Run the installation program for repair the debugger.

I have certainty that it’s not my visual studio but the project. Has anyone gone through something like this? It’s hard to find a solution, follow the error print:

  • this error is when you try to run automated tests? It may be the webdriver that is not installed...

  • No, this error occurs when I run the web application

  • I installed SQL Server Data Tools (SSDT) for Visual Studio 2017 and I have the same problem. It seems that there are a considerable number of people with this problem. Look at this issue in the SQL Server Forum.

  • @Leonardobonetti In this same forum in the post above, I posted a solution that changed my case (look on the page for gwarah). I hope it helps your case.

The problem was solved by changing the door of the http://localhost:54345/ to some other random, example http://localhost:54348/.

According to this article from microsoft, you should follow the following step:

If several versions of Visual Studio have been installed and uninstalled on the computer, WF3 debugging may fail with a of the following two possibilities: Breakpoints were not reached. The following message is displayed: Cannot start debugging on the web server. Debugger not installed correctly. Unable to debug the requested code type. Run the installation to install or repair the debugger. If any one of those scenarios occurs during workflow scrubbing of . NET Framework 3.0 or 3.5, perform an installation repair of Visual Studio.

  • I said the problem is in project and not in Visual Studio, I’ve tried this process :/

    So, but the point is that all the places lead to show that it’s a visual studio problem. For example, you stated that it is not, but as you did not prove, I tried to follow the line that this problem could be. Which VS do you use? tried another version? error persisted? try updating your . net framework...
