我使用以下网址安装了 .NET Framework Core 2.0 运行时:https://www.microsoft.com/net/targeting?utm_source=getdotnetsdk&utm_medium=referral 但是当我打开 Visual Studio (2013) 项目时,我无法选择 2.0 版
You can't do that, it's .net code 2.0, so you will not see that in .net framework.
what you need to do, is to find this and than you will be able to develop on .net code framework
