2015 年 Visual Studio 无法加载 CS 项目
Unable to load CS project in Visual Studio 2015
我已经从 Github 下载了 NetTopologySuite。我无法在我的 Visual Studio 2015 IDE.

所以，它不起作用。
我该如何解决这个问题？
Unable to load CS project in Visual Studio 2015
您的项目似乎是一个新的sdk格式项目（Net Core and Net Standard）。
它使用<Project Sdk="Microsoft.NET.Sdk">而不是传统的项目风格：
<Project ToolsVersion="14.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
并且VS2015不支持新的sdk风格工程
由于VS2017，Microsoft发布了新的sdk风格项目（net core和net standard）。可以参考this document.
=============
还有，你修改的也是new sdk format格式(Microsoft.NET.Sdk)，你写错了
Net Standard 项目不能使用旧样式格式:
<Project ToolsVersion="14.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
解决方案
所以你应该下载使用VS2017或VS2019.
另外，使用vs installer安装时，请确保已安装Net Core workload:
检查两者。
在我这边，我可以从github.
