Hi,
after some time I’m back to .NET Core with Elements

I’ve got the project you uploaded, but when I reference it to [ASP.NET](http://ASP.NET) Core Web Application I’m getting error
Project ‘NetCoreApplication286.elements’ targets ‘.NETCore2.1’. It cannot be referenced by a project that targets ‘.NETCoreApp,Version=v2.1’.
Any idea how to reference it?

Great success 🙂 Changed
.NETCore2.1
to
netcoreapp2.1
and I can reference Elements code to [ASP.NET](http://ASP.NET) Core project 🙂

Success - it would be nice 🙂
I’m trying to add npgsql reference to my .NETCoreApp - could you please look at this?

If you’ll fix sth I’ll be happy to test it (before friday beta) because I’ve got time for it this week 🙂

Curious. here it fails with the rather unhelpful message:
```auto
A JSON parsing exception occurred in [/Users/mh/Downloads/ConsoleApplication3 2/bin/Debug/ConsoleApplication3.deps.json]: Key not found
```
(ok, but WHAT key? the JSON looks fine…)

Don’t know what’s this, but found, that [ASP.NET](http://ASP.NET) Core App builds with .NET 4.5 ClassLib and my code is running - one step forward 🙂

Hi,
when EBuild will build [ASP.NET](http://ASP.NET) Core Web Application - I’ve been trying to run it using VS and MSBuild, but it’s just imposible to work with MSBuild…
Errors like
> MSB4018: The “GenerateDepsFile” task failed unexpectedly.
and it’s the end… References to .NET Core project just do not work.
I want to do it all under Water and forget about VS - will you help? 😉

That’s not EBuild…

Well, just try it — what fails? Create a new .NET Core project from template. change the SDK/Runtime setting to ASP. What happens? Maybe it just works? I just haven’t gotten around to testing [ASP.NET](http://ASP.NET) yet but in theory it should all just work the same as regular .NET Core?

I know that’s no EBuild - I’ve got enough using MSBuild 🙂

Water → New project Console Application (.NET Core) using C# do not build
> Source code file ‘C:\Users\LHeczko\Documents\RemObjects Software\Elements\Water\ConsoleApplication7\Properties\Settings.Designer.swift’ does not exist.
It needs swift file, but its C# project - there is cs file
Oxygene project builds ok, but dont know how to translate some of C# code 🙂

I’ve created .NET Core Console Application, added reference to NuGet Microsoft.AspNetCore.App and there is a problem with multiple references.
> Type “System.Reflection.AssemblyTitleAttribute” is defined in multiple references: System.Runtime, System.Runtime
When I look into References there is Microsoft.AspNetCore.App and Microsoft.NETCore.App - just like in VS - one difference - I can count on you 🙂
Test case:

Please look at this 🙂

I believe you dont want to add this reference, you just want to set the runtime, eg:

Maybe 🙂 But under VS both of this are in references.
