Asp Net Core 2.1 not listed in Visual Studio 2017 target framework

问题

I've installed the new AspNet Core 2.1 SDK - which is now official - but it's still not listed in Visual Studio 2017 target framework, oin both existing projects and new projects:

As suggested in similar topics I've tried with:

• Installing both x64 and x32 versions of the SDK
• Installing the runtime separately
• Manually adding the installation path of the SDK to the environment variable PATH
• Manually updating an existing project (not worked because it wasn't able to find the 2.1 SDK)
• Restarting the PC
• Switching language between my native language (Italian) and English

But it's still not listed.

Reading VS infos, I got that Visual Studio version is 15.7.2 (latest) and NET framework version is 4.3.03056.

Executing dotnet --info from Powershell, i get this:

Does anyone know how to solve that?

Naming is totally confusing. You need to install the 2.1.300-rc1 SDK to get .Net Core 2.1.
