.NET5在 VisualStudio2019中不可用

我已经在 Visual Studio 2019中下载并安装了.NET Core 5.0 SDK (v5.0.100-preview.1)。 但是在 Target 框架中不可用。 我错过了什么吗？

You need to install the latest preview of Visual Studio 2019 16.8, refer to

https://devblogs.microsoft.com/aspnet/asp-net-core-updates-in-net-5-preview-1/

You also need to explicitly enable preview versions within Visual Studio itself:

enable previews

Then you should see it:

Targeting .NET 5 (rc2) doesn't work smoothly in VS Version 16.8.0 Preview 6.0

I could only target .NET 5 by manually changing the .csproj file, and adding:

<TargetFramework>net5.0</TargetFramework>

Specs: VS Version 16.8.0

Target Version of .Net Core: 5.0

You must have version 16.8.0 in order to have .Net Core 5.0

If you still have problems with Visual Studio not showing .Net Core 5.0 in Visual Studio version 16.8.0 (and assuming you downloaded the .NET Core 5.0 SDK for Visual Studio), well, apparently (and correct me if I'm wrong) it is now called just .Net 5.0, omitting the Core.

After selecting .NET 5.0, I was able to install other libraries which are currently version 5.0+ and dependent on .NET Core 5.0+

Is the new name intentional? Anyways, here some evidence of this working (I was able to install the newest version of Newtonsoft and Entity Framework for .Net Core):

Funny enough, when I try to create a new .Net Core project, the version shows up as expected:

I upgraded my version of Visual studio from 16.7.x to 16.8.1. I expected NET 5 to be listed as a target framework, but it was not.

I had previously created projects in 16.8 preview 6 using RC1.

Visual Studio Install did not list .NET 5 as an individual component either. I then downloaded and installed the x64 SDK. Still no luck. .NET5 was still missing as a target framework for VS 16.8.x

Today I opened VS Installer and from the More dropdown menu selected Repair . The repair process took 25-30 minutes to run, but now .NET Core 3.1 and .NET 5 are listed in all the usual places.

Try to set it in your .csproj file. Right click (maybe unload) and edit (within a PropertyGroup-element):

    <TargetFramework>net5.0</TargetFramework>

Maybe a bit late to the party. Please note that if you've selected a 'regular' .NET Framework application you won't see the .NET 5.0 Framework option. This is only visible in .NET Core project styles.

When I wanted to create a solution, .NET 5 was not available, even when I have it installed. What I did to fix this was:

  1. When you are creating the project, select the last version (in my case .NET Core 3.1)
  2. When the project is created, right click on the project and select the Properties option.
  3. In the Application tab, select the Target Framework you want.
