Windows Azure Project web role entry point host stopped error

I have just started development for Azure. I have created an Azure project with Asp.net开发者_如何学Python role, but when I try to debug it without making any changes it gives the following error: "windows azure web role entry point host has stopped working".

Check your %UserProfile%\AppData\Local\Temp directory. You should see a couple files there including IISConfigurator.log and Visual Studio Web Debugger.log. See what those files tell you.

Update: later SDKs have them at %UserProfile%\AppData\Local\dftmp\IISConfiguratorLogs\

Check your %UserProfile%\AppData\Local\Temp directory. You should see a couple files there including IISConfigurator.log

For me on SDK v1.6 the path was %UserProfile%\AppData\Local\dftmp\IISConfiguratorLogs\IISConfigurator.log (be careful with the latest SDKs, it looks like they have changed the path) The problem was with the line 'Adding access to users IUSR and NT AUTHORITY\NETWORK SERVICE to path %MyPathOnTheBuildMachine%':

It turned out that I packaged (cspack) my solution on one machine, but tried to run it (csrun) on the other one. So it tried to give the rights to the directory that exist on one machine, but doesn't exist on the other one.

So many sure you cspack and csrun your code on the same machine (which might not be the case when you do automated build&deploy for example).
