RC2 IISExpress: Error -4092 EACCES permission denied

[kspearrin]

After moving from RC1 to RC2 I am getting the following error when trying to start up the application via VS on IISExpress:

Error -4092 EACCES permission denied

Running the application via the Project "Web" command runs just fine. This is just an issue when running via IISExpress. I have tried changing the port (4009 currently), deleting bin/obj folders, deleting .vs folder, deleting project.lock.json without success. Any idea what's going on here?

This is probably a duplicate of https://github.com/aspnet/IISIntegration/issues/176 where the project name Web causes issues.

[kspearrin]

That is correct. This project is named "Web". Only workaround is to rename the project at the moment?

[davidfowl]

Rename the project.

[kspearrin]

For others: Confirmed renaming the project solves the issue (directory structure can remain in place). Also had to delete the .vs folder and bin/obj to "reset" the config bindings.
