IISProblem

ASP.NET Core solution showing problem with IISExpress and renamed project directory

Steps to recreate solution (and problem)

1. Open VS 2015 Community Edition
2. Create new project and select ASP.NET Core Web Application (.NET Core) project type
3. Name solution as e.g. BrainCrumbz.IISProblem, name project as e.g. BrainCrumbz.IISProblem.MyProject
4. Select Empty web application type
5. Save all. Do not run, nor build, so not to create hidden .vs\config\applicationhost.config yet
6. Remove project
7. Rename project folder to e.g. just MyProject
8. Add back existing project from renamed folder
9. Add explicit project name, title and version in project.json:

"name": "BrainCrumbz.IISProblem.MyProject",
"title": "BrainCrumbz.IISProblem.MyProject",
"version": "0.0.0",

1. Make sure IIS Express profile is selected (the default)
2. Run

Expected

• VS stays running in debug mode. Browser shows Hello world text
• Windows Event Viewer, Applications log, shows a warning by IIS Express. We're seeing that on working web applications as well, it seems related to Bitdefender (issue 309 and StackOverflow) and it seems not having effects on this issue

The directory specified for caching compressed content C:\Users@@@USERNAME@@@\AppData\Local\Temp\iisexpress\IIS Temporary Compressed Files\Clr4IntegratedAppPool is invalid. Static compression is being disabled

• Following warning, there's an Information event by IIS Express AspNetCore Module with success message:

Process '10016' started successfully and is listening on port '11928'.

Actual

• VS stops and leaves debug mode unexpectedly. Browser shows Server unreachable page
• Windows Event Viewer, Applications log, shows same warning as before
• Following warning, there's an Error event by IIS Express AspNetCore Module:

Failed to start process with commandline '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web Tools\ProjectSystem\VSIISExeLauncher.exe" -debug -p "C:\Program Files\dotnet\dotnet.exe" -a "D:\WS\NET\ASP.NET-Core\BrainCrumbz.IISProblem\src\MyProject\bin\Debug\netcoreapp1.0\MyProject.dll" -pidFile "C:\Users@@@USERNAME@@@\AppData\Local\Temp\tmpF450.tmp" -wd "D:\WS\NET\ASP.NET-Core\BrainCrumbz.IISProblem\src\MyProject"', ErrorCode = '0x80004005'.
