I am working with .Net Core 1.0 (running under the .Net Framework 4.6.1, non-portable).
I need to include some DLLs that are from a locally-built GitHub project. When I build those projects, and then attempt to "Add Reference" to the resulting DLLs, I get a message saying I can't add them to a Core project directly.
After more research, I found a lot of information regarding "private" NuGet packages. However, those seem overly complex / overly engineered.
Is there any way I can do the following:
Without having to go through the headache of creating a private NuGet repository, can I just "add reference" to the built assemblies that are sitting in the bin folder of the NuGet projects I pulled?
I really don't want to have to build a local-only NuGet package. Mostly because I've already wasted too much time on this issue, and because I read this entire concept is about to be scrapped and turned into something else (sounds familiar by now)... such as the Roslyn-based build system on GitHub.
My current state:
Visual Studio Professional 2015
.Net Core 1.0.1
.Net Core 1.0.1 Tooling Preview 2
No, as for now you have to create a nuget package before and restore it via Nuget. You can use a simple folder as NuGet source, so if you put your compiled NuGet package in C:\packages, you can add this as a source to NuGet (while in the NuGet UI, click the settings Icon and add the folder as new source).
This may change with the next release of ASP.NET Core (1.1), as the .NET/ASP.NET Core team is working to move from *.xproj to *.csproj files.
One of the reasons why you need to use nuget is because it can contain multiple targets and project.json allows you to target multiple platforms (i.e. net452 and netcoreapp1.0).

I have a question about .net Core project.
I have a .Net Core Project referencing other projects.
The problem is that a few projects show the warning saying that "Package 'XXXXX' was restored using .NetFramework, Version=v4.6.1.... instead of targer framework .NetCoreApp".
What kind of problems could I have?
Also can I deploy this in Linux for instance and still working fine?
warning showed
Thanks guys
Look at this thread - For a .Net Core 2.1 project, Why does Nuget restores .Net 4.6.1 packages?
What it basically means is the package you have loaded not suitable for .NET CORE, and was restored using a different version of .Net Framework.
Check if the package exists for .NET CORE (search thru NuGet Manager)
Regarding whether it will work on Linux or not - it depends on the package dependencies (e.g. if it is depending on WinForm for example, it probably won't work on Linux).
Even if it will work, I suggest finding a package suitable for .NET CORE.
If I create a .NET Core Class Library in Visual Studio 2017, I get the Package tab on project properties. If I create an "old fashioned" Class Library, I do not get the Package tab, nor the "Pack" target in MSBuild.
NuGet is integrated into VS2017 and MSBuild to some degree, but it seems to be only for .NET Core projects.
Is there a way to use any of the NuGet integration for non-.NET Core projects or do I just need to install the NuGet CLI and use a .nuspec file?
This support for integrated packaging needs "SDK-style" csproj files which are used for .NET Core and .NET Standard projects. Since a few features (like some designers) aren't yet available for these projects, there are no templates for "SDK-style" csproj-based projects for .NET Standard.
However, you can create a .NET Standard project and change the csproj file from
<TargetFramework>netstandard1.6</TargetFramework>
to a net* moniker like
<TargetFramework>net461</TargetFramework>
This gives you all the tooling for creating NuGet packages and managing versions and metadata.
I am trying to build a .NET Core application. For this purpose I create a new MVC project from the template ASP.NET Core Web Application (.NET Core).
Once I do this, I inevitably need to install some NuGet packages, and see that there are 26 updates available for my project. So I hit "update all" and get into a big mess. One was having to manually edit the project.json to make the .NETCore.App an object with {"version":"2.0.0","type":"platform"}. Now in the project.json most of the stuff is at version 2.0.0 but I get all these error messages in the Error List, and all of them say pretty much the same thing: The dependency Microsoft.AspNetCore.Authentication.Cookies 2.0.0 does not support framework .NETCoreApp,Version=v1.0
What is my missing step?
Answer came in form of comment:
VS2015 is no longer supported for .Net Core projects. You need to upgrade and migrate your project.json to .csproj too. – DavidG
I know VS 2017 is only RC but there seem to be some major issues with migrating an ASP.Net Core 1.0 project to 1.1. The migration tool fails converting 2 of my 8 projects in the solution (I prefer to adopt a layered architectural approach for my projects) the sample project is located here. One project in particular is the class library I moved my web api controller methods into. In trying to re-create this class library it doesn't seem one is able to declare a controller class after installing Microsoft.AspNetCore.Mvc nuget. It is installed but the compiler is not finding the Controller, RouteAttribute classes, etc. The same issue occured with trying to setup a DI layer IServiceCollection. Nuget Microsoft.Extensions.DependencyInjection doesn't seem to be doing it.
The migration log quite honestly isn't really helping me. It seems to indicate an issue with my service project and the project.json file but as you can tell it is in the repository.
It feels like Microsoft is forcing us down the path of cramming all the "web" stuff into a single project file. Maybe these tools aren't far enough along yet but an RC would indicate they should be closer to ship ready?

I can't directly speak to VS2017 as I'm staying away from it as even though it's a RC, the core tooling is in ALPHA. The VS 2015 core tooling is at least in a "RC" state (actually only preview).
In VS2015 I migrated from 1.0.x to 1.1 manually (per https://blogs.msdn.microsoft.com/dotnet/2016/11/16/announcing-net-core-1-1/):
Download the 1.1 sdk
Change your global.json "sdk":{"version": "1.0.0-preview2-1-003177"} (yes it's a different version string).
Update all the project.json package versions from 1.0 to 1.1 (some are preview some arn't). Just open up the nuget package manager, allow preview versions, then install all the updates.
Fix any of your project.json tool entries as the package manager clobbers those.
I started programming with .NET Core and ASP.NET Core and after reading many Docs/Tutorials i still am not sure of how to realize if a Nuget-(Meta-)Package is comptabile/usable within my .NET-Core-App.
How to check if a NuGet-Package is compatible with .NET Core.
E.g. the often recited Newtonsoft JSON. Is it compatible/usable - and how to see this?
Is there a list of all the available .NET Core packages?
(Like here it lists a few
key NuGet packages for .NET Core
). But since they say those are "key" packages i would assume there are more. But which?
The best way to understand compatibility is table here
In this table you can check what API version support NuGet package. If it is standard 1.0+ - it works with .Net Core
For checking (supported API version) dependencies on your package, you can check page of package on nuget.org or in your package manager
Here is an example for Rider
maybe that will be helpful - lots of popular packages https://github.com/thangchung/awesome-dotnet-core
I also don't see nuget.org mentioned anywhere so:
https://nuget.org
General rule of thumb for me is:
if package has a dependency on net standard or .net core, it will run with .net core(mind the versions also)
https://packagesearch.azurewebsites.net
Go to site and search for package to find its compatibility
Well, in fact you don't have to worry, the NET core application will indicate you if the package is compatible or not when you will run a dotnet restore command in your project.
Let say that you have the famous CSVHelper package registered in your csproj file :
<PackageReference Include="CsvHelper" Version="0.12.0"/>
Then, when you'll run any dotnet command such as build or run, you'll have the following input in the console in case of, here, cross-compatibility:
YourProjet/aspnetapp.csproj : warning NU1701: Package 'CsvHelper 0.12.0' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8' instead of the project target framework '.NETCoreApp,Version=v2.2'. This package may not be fully compatible with your project.
Basically, it mean that NET Core application can use ASP.NET NuGet package, and so far, I've never cross on a non-compatible package. Even if version is incorrect, the build will get the most recent matching version of the NuGet package.
Hoped it answer your question.
