Your first Mac ASP.NET app tutorial problems

[TravisTheTechie]

1. Says should use 1.0.0-beta4. Can't install beta4 from the feed... dnvm install 1.0.0-beta4 nor dnvm install 1.0.0-beta4 -u. (semi-related, where do I report that empty directories in ~/.dnx/runtimes for failed installs is annoying?)
2. Screen shots don't match the current generator-aspnet options.
3. Can't get the dnu commands to run from VS Code, but that might be an issue on my end. OmniSharp won't start up either and might be related. They do run from the command line, so good enough.
4. Kestrel is already in the project.json
5. Bug in the beta5 version of Kestrel, have to export MONO_MANAGED_WATCHER=false or eat all the file descriptors.
6. Kestrel just reports TypeLoadException: Could not load type 'Microsoft.Framework.Runtime.ILibraryExport' from assembly 'Microsoft.Framework.Runtime.Interfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. when I try to load a page after dnx . kestrel.

This should be fixed now. Installing beta4 should work /cc @glennc

That is likely the problem. Omnisharp tells VSCode about the commands.

Bug in the beta5 version of Kestrel, have to export MONO_MANAGED_WATCHER=false or eat all the file descriptors.

Nothing to do with Kestrel. It's a mono issue likely caused by Razor view compilation.

Kestrel just reports TypeLoadException: Could not load type 'Microsoft.Framework.Runtime.ILibraryExport' from assembly 'Microsoft.Framework.Runtime.Interfaces, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. when I try to load a page after dnx . kestrel.

Sounds like you've mismatched beta4 and beta5 bits. They are incompatible.

[TravisTheTechie]

So it sounds like not having beta4 is the source of all my issues.

$ brew update && brew upgrade

This is most likely caused by the feed not having the version that you typed. Check that you typed the right version and try again. Other possible causes are the feed doesn't have a DNX of the right name format or some other error caused a 404 on the server.

I also tried 1.0.0.0-beta4 per OmniSharp/generator-aspnet#149 (comment) without success.

How do I get beta4 then?

[TravisTheTechie]

https://www.nuget.org/packages/dnx-mono/1.0.0-beta4 exits, so, dnvm install 1.0.0-beta4 should work, right?

$ dnvm install latest
Determining latest version
Error: Could not find latest version from feed https://nuget.org/api/v2

Maybe that's the issue, something with nuget?

[TravisTheTechie]

Lame...

$ open https://nuget.org/api/v2/package/dnx-mono/1.0.0-beta4
# ... wait for download
$ dnvm install ~/Downloads/dnx-mono.1.0.0-beta4.nupkg -p

And poof web pages load now without error pages.

[davidfowl]

Nothing wrong with NuGet. Try dnvm update-self aspnet/dnvm#235

[kelong]

@TravisTheTechie still same error after installing manually.

[TravisTheTechie]

Does dnvm list show beta4 as the default and active one? You might need to dnvm use 1.0.0-beta4. Still running into the mono issue with kestrel would indicate you're still using beta5.

[kelong]

@TravisTheTechie I have never installed beta5 version.
