Let's say I have:
ASP.NET Core stand alone Web API project for .NET Core framework
Class Library with EF6 data model for full .NET framework
The ASP.NET Core project refers to the class library
This architecture proposed here:
https://learn.microsoft.com/en-us/aspnet/core/data/entity-framework-6
The question is: will my standalone application be able to execute on the specified target platform (Win, Linux, Mac runtime) after Release (or Publish), if it's dependency targets to full .NET Framework?
Thanks very much
It will be not possible. The same link you provided confirm that:
To use Entity Framework 6, your project has to compile against .NET Framework, as Entity Framework 6 does not support .NET Core. If you need cross-platform features you will need to upgrade to Entity Framework Core.
You can use ASP.NET Core upon .NET Framework (Not .NET CORE) and EF6 (But not cross-platform). But not ASP.NET Core upon .NET Core and use EF6. You will need to use EF Core for that project.
Disclaimer: I'm the owner of the project Entity Framework Classic
That's not possible directly Entity Framework as #Adailson answered
However, it's possible via EF Classic: http://entityframework-classic.net/
That's an EF6 fork that also supports .NET Core. We plan to integrate a ton of features & bug fix.
A community (FREE) and enterprise version (PAID) is available.
What's EF Classic
Entity Framework Classic is a supported version from the latest EF6 code base. It supports .NET Framework and .NET Core and overcomes some EF limitations by adding tons of must-haves built-in features.

I'm trying to change ASP.NET Core web application with .NET Framework as a target framework to use .NET Core 3.1.X
I try changing the target framework in the project file (.csproj), I encounter dependency issues, dependency conflict....
Is there any straightforward method to solve this issue?
Before you start your migration, you should know there’s several difference between .net framework and .net core, so please follow the official document to do some Pre-Migration steps.
Then you can follow this official document to migrate your application from framework to .net core 3.1.
Since your ideal .net core version is 3.1, still I suggest you can try to use .net 6. Also, you can use this upgrade tool to reach your goal. In fact, using this upgrade assistant is a batter choice than you doing it by yourself. Even if you are insisting using .net core 3.1, you can use this assistant to upgrade your version to 6 first then change it to 3.1.
Note:
Before you start your migration, please make a backup of your original project. That's because some packages in .net framework may be no longer available in .net core. So if there're some errors occur, you can go back to the original one.
Microsoft.Web.Infrastructure.dll is being used in a .NET Framework project that I am trying to migrate to .NET Core and ASP.NET Core.
I already tried searching on Google and couldn't find a direct relation - any help about if there are any alternatives would be appreciated.
NuGet doesn't say that there is any .NET Core versions of it, only .NET Framework so I'm asking here
I was creating .net core web application and can see .NetFramework with .NetCore support. But I didn't choose .Net Standard. I don't understand. Please see the image asp.net core web application
This is Microsoft naming at work here. 😁 There are two dotnet frameworks: the "full" framework, which you selected, and the dotnet core framework.
Before dotnet core and all it's optimized, multiplatform goodness, there was the dotnet framework (refered to as the legacy or full framework). This is the predecessor of dotnet core. This full framework runs only on Windows and the computer it runs on needs the dotnet framework runtime.
Do not worry, the "full" in full framework comes from the transition period between the old dotnet framework and dotnet core. When dotnet core was version 1.0, it did not have all the functionality of today. So some developers called it the full framework (which had everything you needed to run your application) and the newer dotnet core framework which had only the basics.
You can see if you are running the legacy framework if there is the <TargetFramework>netXXX</TargetFramework> present in your solution/project file. The lastest version of the full dotnet framework is 4.8 (net48).
After that it switched to dotnet core 1.0 - 3.1. I'm not entirely sure how that's referenced in the solution/project files.
As a last remark, Microsoft had a great naming idea: the next version of dotnet core is named dotnet 5. They want to get back to the original name with this next version. Do keep in mind that you cannot easily upgrade from dotnet 4.X to dotnet 5. The day to day code looks very much alike, but the underlying engine is completely rewritten.
As far as I know, before .net core 3.0, asp.net core is support on .net framework. This is the reason why you could create .net core 2.1 on the .net framework.
But after 3.0, asp.net core not support .net framework. You could only create it on .net core framework.
More details, you could refer to this article and this github issue.
I have an ASP NET MVC project with net471 target framework but I found nuget reference to Microsoft.AspNetCore.* or Microsoft.EntityFrameworkCore.*
It's correct? What problems can it entail?
It depends. First, I'm not sure if you're using terminology correct. Do you have an ASP.NET MVC 5 project or an ASP.NET Core project? If the former, then yes, it's very much incorrect. If the latter, then no it's fine, depending on the ASP.NET Core version.
.NET Framework 4.7.1 implements .NET Standard 2.0, which .NET Core 2.2 is also compatible with. Therefore, you can include ASP.NET Core 2.2 packages in a .NET Framework 4.7.1 project. Despite the name, an ASP.NET Core web app doesn't have to actually run on .NET Core. However, ASP.NET Core 3.0 or EF Core 3.0 would not work because those depend on .NET Standard 2.1, which no version of .NET Framework implements (and probably never will).
What exactly is the difference between .NET Core and ASP.NET Core?
Are they mutually exclusive? I heard ASP.NET Core is built on .NET Core, but it can also be built on the full .NET framework.
So what exactly is ASP.NET Core?
Update 2020: Do note that ASP.NET Core 3 and higher now depend on .NET Core and can no longer be used on .NET Framework. The below description is for ASP.NET Core 1.x-2.x; the layer separation still holds true for ASP.NET Core 3.0 but the ASP.NET Core layer can no longer be used on top of .NET Framework in 3.0+.
.NET Core is a runtime. It can execute applications that are built for it.
ASP.NET Core is a collection of libraries that form a Framework for building web applications.
ASP.NET Core libraries can be used on both .NET Core and the "Full .NET Framework" (which has shipped with windows for many years).
The confusing part is that an application using the libraries and tools of ASP.NET Core is usually referred to as "ASP.NET Core Application", which in theory doesn't say if it is built for .NET Core or .NET Framework. So an "ASP.NET Core Application" is also a ".NET Core Application" or a ".NET Framework Application".
This image shows the relation of the involved technologies (taken from this blog post)
Here you can see that ASP.NET Core is built "on top of" both .NET Framework and .NET Core, while "ASP.NET" (now often referred to as "classic ASP.NET") is .NET Framework only.
ASP.NET Core using .NET Core - all dependencies are self-contained, can use most NuGet packages, can't use Windows-specific packages, can execute on Windows, Linux, and Mac.
ASP.NET Core using .NET Framework - most dependencies are self-contained, only executes on Windows, will have access to Windows-specific NuGet packages, needs the .NET framework version which is targeted installed on the machine.
ASP.NET Core is one of the workloads supported by .NET Core.
From .NET Core guide:
By itself, .NET Core includes a single application model -- console apps -- which is useful for tools, local services and text-based games. Additional application models have been built on top of .NET Core to extend its functionality, such as:
ASP.NET Core
Windows 10 Universal Windows Platform (UWP)
Xamarin.Forms
The .NET Framework is on its last release. There will not be another one after 4.8. Microsoft will continue with .NET Core. From this time you should prefer .NET Core on your projects.
Official update (source):
.NET 5 is the next major release of .NET Core following 3.1. We named this new release .NET 5 instead of .NET Core 4 for two reasons:
We skipped version numbers 4.x to avoid confusion with .NET Framework 4.x.
We dropped "Core" from the name to emphasize that this is the main implementation of .NET going forward. .NET 5 supports more types of apps and more platforms than .NET Core or .NET Framework.
ASP.NET Core 5.0 is based on .NET 5 but retains the name "Core" to avoid confusing it with ASP.NET MVC 5. Likewise, Entity Framework Core 5.0 retains the name "Core" to avoid confusing it with Entity Framework 5 and 6.
.NET Core is the next evolution of the .NET Framework, that allows Microsoft technology to be hosted on other OS platforms, rather than Windows.
ASP.NET is the web framework provided by Microsoft for building:
server-side rendered web pages/websites
server-side components for SPAs
MVC-fashion apps
web services/web APIs/microservices
ASP.NET runs only on Windows platforms.
Since .NET Core was created to provide the capability of running Microsoft tech on top of Linux/macOS, it implies that ASP.NET Core is the evolution of ASP.NET in the direction of multi-platform support.
In conclusion:
ASP.NET Core runs on both .NET Core and .NET 5.0, on top of multiple OS platforms: Windows, Linux & macOS.
ASP.NET 4.x (ASP.NET/ASP.NET MVC) runs on the .NET Framework only, on top of Windows OS.
