Discussion for: ASP.NET Core RC2 is no longer compatible with DNX

[Eilon]

Discussion for aspnet/Announcements#176.

Hi all,

ASP.NET Core RC2 is now compatible only with .NET CLI. ASP.NET Core RC2 is no longer compatible with DNX.

You can read more about the transition from DNX to .NET CLI on these blog posts:

• ASP.NET 5 is dead – Introducing ASP.NET Core 1.0 and .NET Core 1.0
• An Update on ASP.NET Core and .NET Core

This means that using Visual Studio 2015 with the ASP.NET 5 RC1 tooling will no longer work with the latest nightly builds (i.e. packages coming from https://www.myget.org/gallery/aspnetvnext). The RC1 tooling supports only DNX.

We kept everything compatible with DNX for as long as possible, but eventually we had to separate the two in order to help ship the ASP.NET Core RC2 release.

We are working on finalizing the ASP.NET Core RC2 release, including updated tooling and project templates for Visual Studio.

Visual Studio Code in the meantime works very well with ASP.NET Core RC2 nightly builds.

Thanks,
Eilon

Is there an expected date for rc2?

[smbecker]

Nothing announced yet. At the last community stand-up, it was mentioned that there would be some announcements at the stand-up next week.

@304NotModified expect announcements very soon!

Hi, is there any way to debug unit tests with .NET CLI? I could not find a way, except run all at once.

Is it possible to run RC2 nightlies on Mono just like we did with RC1/DNX? CoreCLR still has lots of problems on any Linux distribution except the very old Ubunutu 14.04: it just segfaults here on my Debian unstable while RC1/DNX/Mono worked without a hitch.

Is it possible for us to just specify the previous nightlies from before this change was made, so we can avoid having to reconfigure our build server and entire build process. Can we specify a previous version whilst still using the same package feed?

Is there a list of what is not compatible?

Also, there is so much conflicting information across the board of Microsoft websites now, will some time be allocated to removing documentation which is no longer relevant? I think the amount of out of date documentation is going to cause confusion over time and make adopting the new platform a slow and painful process.

Let's be blunt, we are stepping back to a time when you read the underlying code to understand the structure. Documentation is way behind. While interesting that Microsoft is opening documentation process to outside, if Microsoft doesn't have time to write the documentation, unlikely that users will.

Now, I love ASP.NET 5 and MVC 6. But I almost at the stage to put on back burner a transition to it for a website. I have survived much of RC1 despite much trouble finding documentation for how to do things. I have read more underlying code, especially Microsoft's, than I have done since the 80's. Much of Microsoft's documentation is incorrect and relates mostly to Beta8. And based on what I see with RC2, I will have a lot of work to do to transition from RC1 to RC2, despite what the standup video claims.

I guess I should have listened when Microsoft suggested to hold off doing live with RC1 (and I assume that will hold with RC2). ASP.NET 5 is such a moving target. RC1 should have been called Beta 9. By RC1, I expected the base structures to have solidified and minor tweaks on out to manufacturing release. Unfortunately, this is not the case. Honestly doubt that we will see RC2 before July and cannot see any way that final manufacturing version will be done in 2016. When you are still changing namespaces in RC2, Microsoft has lost site of the goal - get users using it.

I hate to beat down on ASP.NET 5/MVC 6. I just love it but time to put this on the shelf and go back to improving my MVC 5 version of the website, and wait to start back up in 2017 with final release.

Documentation is way behind.

Well, not really. The docs for RC2 release have been under heavy development, and they are available in the dev branch. They will be flipped into latest (master branch) when RC2 releases. You do have access to them. It's just not widely advertised that you can see them now on the dev branch.

Being under development, the docs coming out soon might not be accurate or complete. I'm working on one today that has real bugs in the text, and I'll be getting those bug-a-boos out this morning. However, you can get to them in the Docs repo in the dev branch https://github.com/aspnet/Docs/tree/dev. Also, note that the naming changed to ASP.NET Core 1.0 and MVC Core 1.0 in aspnet/Announcements#144.

I installed the C# extension in VS Code and it didn't seem to work with an existing .NET CLI project.
