Having some issues getting my .NET Core projects to build. I get the following error after enabling NCrunch:

They're using csproj, not project.json, and I'm targeting netstandard1.4. What am I missing here?

Just read the support notes about the priority of this for 3.3. That's no problem. If this is something I can fix on my end, or I can provide information to help debug, let me know. Otherwise, I'll go back to waiting patiently.

Hi, thanks for sharing this issue.

As you've discovered, .NET Core build support is still a work in progress. Though I'd really like to know more about this problem to make sure it's properly handled in the next release. Is there any chance you could share with me the non-source components of your .csproj and project.json files? I'd like to be able to recreate this so I can investigate further.

Absolutely. Is there somewhere I can email these instead of tossing them up here?

Sure, just put them through the contact form at https://www.ncrunch.net/support/contact. I only need the structural parts of these files to figure out how to produce the problem. Any domain related elements you a very welcome to remove if you are concerned about IP.

I think we're getting somewhere. I'm getting an error on a few projects, but it seems to be related to this issue: https://github.com/dotnet/sdk/pull/478

I'm going to update the projects with problems with deep references and see if I can get them to build. I'll let you know how it turns out.

Less sure about that now. I've taken the two simplest projects in the solution. The first one has no other project dependencies and built fine in NCrunch out of the box. The other threw the error I'm seeing. I duplicated all nuget references directly into the other project so that there's no way it's using any transitive project references that I can see. Same error, even after unloading/reloading, etc.

I'm going to keep playing with it, but it may still be a genuine issue.

Here's the error:

Thanks! I've managed to reproduce this. It looks to be related to how .NET Core handles project references.

I have a few other improvements for the .NET Core support in the works. I'll try to get a fix out with these later in the week.
