Visual Studio 2017 not support targeting .NET Core 3.0

Question

I have tried installing SDK 3.0.1 in Visual Studio 2017 --version 15.9.16. When I open a new web application I get an error saying:

"Severity Code Description Project File Line Suppression State Error NETSDK1045 The current .NET SDK does not support targeting .NET Core 3.0. Either target .NET Core 2.2 or lower, or use a version of the .NET SDK that supports .NET Core 3.0. IdentityServer-C:\ProgramFiles\dotnet\sdk\2.2.106\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.TargetFrameworkInference.targets 137"

Visual Studio 2017 doesn't support .NET Core 3. You need Visual Studio 2019 16.3 or higher. You can find this information in the .NET Core 3.0 announcement.

Visual Studio 2019 16.3 and Visual Studio for Mac 8.3 were also released [on 23 september 2019] and are required update to use .NET Core 3.0 with Visual Studio.
