7,805 Points500 Error
I keep getting a 500 error every time I run the site. I've gone through the video multiple times and every line of code and file name matches. Has anyone else encountered this problem and been able to fix it? Thanks

31,722 PointsInteresting, Some googling turned up this could be a MS bug that was fixed in RC2, do you know the version of .NET you are currently running?

7,805 PointsI am running this using Xamarin on a Mac which could be part of the problem, although it hasn't caused any issues until now. In the process of creating the files, I didn't see an option to view the version of .NET that was being used. Is there a way to check this for Xamarin or is this completely dependent on the current update?
Samuel Ferree
31,722 Pointshmm, never worked with xamarin on a mac.... This may be beyond my skill to heal...
see if you can google how to verify your version of .NET for xamarin on mac.

7,805 PointsEverything I have read online seems to say my version of Xamarin is running .Net 4.5

Treehouse TeacherDavis,
If you can share your project with me (GitHub repo?), I'd be happy to debug it using Xamarin Studio on my Mac.
Thanks ~James

7,805 PointsThanks James. I'm fairly new to GitHub, but I think I found how to add you as a collaborator. What username do you use on GitHub? Thanks again for any help.

Treehouse TeacherDavis,
I was able to clone the repo. And I was able to successfully run the project and browse to "http://127.0.0.1:8080/ComicBooks/Detail" using both Xamarin Studio Community (6.0.2 build 73) and Visual Studio for Mac (Preview 3 [7.0 build 1077]).
I'm currently running Mono 4.8.0.
What versions are you using?
Thanks ~James

7,805 PointsI uninstalled and reinstalled xamarin and updated everything and it now seems to work, although I noticed the URL seems to be case sensitive. Is this always the case?

Well, Its like asking “Does science studies have future?”, one will definitely counter ask “Which stream/major? computer science, physics, chemistry etc?” You get my point.
Aspnet is mix of components, libraries and languages. So valid questions could be:
Is C#/VB case sensitive? C#: YES, VB: NO,
Are URLs case sensitive? NO,
What about ASPX/Razor pages? These are view engines and view pages are written on top them are mix of html and C#/VB. HTML is case insensitive ( but attributes values are: id, class values)
Are configuration files case sensitive? YES its just XML.
Happy Coding!

3,142 PointsI had a 500 error. I had to do Two things:
I had to removed System.web.entities and replace it with System.Web.Http.Common
This then led to another error with MvcWebRazorHostFactory, This required me to update from Version=5.2.3.0, to Version=5.2.7.0 in the view -> web.config file.
After this it finally worked.

31,722 PointsCan you paste the error?
Is there a stack trace that goes a long with it? Is anything printing to your console?
500 Error encompasses every possible server error, so any extra information you have will be super helfpul.
