MVC module gives exception on attempt to access css or js files. Including default module.css.

Description of bug

MVC module can’t use neither css nor js files.

P.S. I’ve also reported this bug to DotNetNuke Module and Theme Development Template. Not sure which repo is a correct one to report this one. If I should delete one of them - please let me know.

Steps to reproduce

1. Create DAL2 MVC Module
2. Compile and install that module
3. Make sure you’re logged in as superuser to see details of all errors
4. Open dev tools and see error in console
5. Look for module.css link in a source tab of dev tools and try to open link to module.css of your module in a new tab and see detailed error message

Current behavior

Assets files (css, js) are not able to be used in an MVC module.

Expected behavior

Assets files (css, js) should be available for usage in an MVC module.

Error information

For default module.css dev tools’ console has this error: Failed to load resource: the server responded with a status of 500 (Internal Server Error) module.css

And when I try to open link to module.css of my module in a separate tab I get this error text:

Yes, that’s what leads me to believe that there’s an issue with a subfolder application or virtual directory, which would only affect requests to that path. Another option is that the web.config file in the DesktopModules/MVC folder has some strange configuration in it which is causing the error only for that path.

This appears to be an issue with the project. I personally have numerous MVC modules on all recent versions of DNN Platform and don’t have this issue. You’ll want to continue troubleshooting with Chris Hammond. The project packaging and source code for your project/solution is the most likely cause unless you have a different set of steps to reproduce. Sorry.
