IApplicationBuilder claims it is defined in 'Microsoft.AspNet.Http'

[rkeithhill]

I have been working on porting an ASP.NET MVC 4 site to ASP.NET 5. I first got it working on dnx451 and then today on dnxcore50 (1.0.0-beta4). Yay! However when I set the project properties to target 1.0.0-beta5-11911 and run the web site I get an ArgumentNullException:

So I figure perhaps I need to ensure that I'm getting newer assemblies. So in my project.json file I changed the dependencies package versions from x.0.0-beta4 to x.0.0-*. That gave me a few compile errors (Session state API change SetInt to SetInt32) which I fixed but I'm stuck on this cryptic error:

Severity    Code    Description Project File    Line
Error   CS7069  Reference to type 'IApplicationBuilder' claims it is defined in 'Microsoft.AspNet.Http', but it could not be found  WebSiteDnxcore.DNX Core 5.0 C:\Tfs\Cdf\Branches\Feature\LxiWebSiteOnAspNet5\Samples\Source\WebSiteDnxcore\src\WebSiteDnxcore\Startup.cs 64

Is this a bug or am I doing something wrong?

[rkeithhill]

Oops. Just realized I was in Diagnostics when I thought I was in Aspnet\Home. Sorry about that.

@rkeithhill First thing, when you run into issues like these, plese file them on aspnet/Home. This repository has nothing to do with the errors you're running into.

Second thing, if you're going to use -*, then you should keep watching the https://github.com/aspnet/Announcements/issues for updates on breaking changes and how to fix them in your applicaiton.

[rkeithhill]

@davidfowl Yeah, sorry about the wrong location and thanks for the pointer to the announcements.

Is there a better way to specify package versions? My ultimate goal is to get the site running on Ubuntu but there is no dnx-coreclr-linux-x64-1.0.0-beta4 package AFAICT. So I'm riding the bleeding edge of dev builds to see if I can get this demo going before a big internal review of our future development processes i.e. do we continue to use ASP.NET or move to PHP as we migrate to Linux for our embedded devices.

[davidfowl]

coreclr on linux is currently broken but we're working on fixing it.

@rkeithhill aspnet/Announcements#14 and aspnet/Announcements#11

[rkeithhill]

@davidfowl Heheh, I was just looking at #14. Thanks for the pointer to #11 and also for the heads up on the state of coreclr on Linux. Been banging my head on this most of the day. I guess this is as good an excuse as any to call it a day. Thanks again.

[rkeithhill]

BTW in my case, commenting out app.UseBrowserLink(); eliminated the build errors but that gets me back to the ArgumentNullException at startup (apparently while reading the lock file).

@rkeithhill it might be more efficient to come to https://jabbr.net/#/rooms/AspNetvNext
