Visual Studio 2013 Azure项目：无法开始调试

Question

I have an Azure MVC project, and when I try to debug it, it hangs at "Starting the role for the application in the Microsoft Azure compute emulator..."

After a while, if I try to hit the debug button again, it gives the error "The debugger cannot continue running the process. Unable to start debugging."

Any idea what the problem could be? The Azure storage emulator is running when this happens.

Answer 1

There are various things that can cause this and they are not all easy to find! It can be caused by a mismatch between the version of Azure tools referenced in the project and that installed on your PC.

I have had to remove everything related to Azure once and reinstall from scratch!

Another potential problem is if your WebRole.OnStart method keeps erroring, in which case, Azure will attempt to continually restart it and that can carry on for a long time. If this happens, it should eventually tell you that the roles are taking too long to start.

There can be problems if you are trying to use IIS instead of IIS Express, I have never got full IIS to work with the Azure debugger.

Try building a simple Azure app that references a default MVC app as a way to make sure it is not caused by mistakes you have made in your code or configuration. Good luck!

Not sure if this is your exact issue or not but I found the following which fixed my problem: https://stackoverflow.com/a/35407737/1399978 . Issue is due to a specific Windows security update ( KB3126593 ). Uninstall the update an everything works as it should. Hope it helps.

I know this might not help a lot of people who have been having similar problems, but I just want to note here that my issues went away when I upgraded to Visual Studio 2015 and Azure 2.8. Thanks for all the input, everybody!
