how to migrate from the (deprecated) project.json format to the new .csproj format.
First, Microsoft greatly simplified the .csproj format. In minimal format, this is what it looks like:
首先，微软大大简化.csproj格式。最小的格式，如下：
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netstandard1.4</TargetFramework>
</PropertyGroup>
</Project>
Second, the good things of project.json were ported over to the new .csproj format:
其次，project.json 的优点都移植到了新的csproj格式：
支持通配符（如果一个文件被添加到项目文件，没有更多的合并冲突）。
命令行工具如dotnet.exe可以跟他们一起工作。
Multi-targeting很简单：只需指定目标框架（target frameworks），就可以了。
包引用和项目引用很容易添加。
从项目中构建包也更容易(see full reference)。
迁移：
Let’s look at how we can move from project.json (and the old .xproj) to the new and shiny. Before starting, make sure that the required toolsets are installed. On Windows, you currently need a Visual Studio 2017 install (we’re working on that). On Mac OS / Linux, the Mono tooling is required.

执行命令出现错误
$ dotnet migrate No executable found matching command "dotnet-migrate"
Note: If you get an error “No executable found matching command dotnet-migrate”, edit the solution’s global.json file and change the SDK version to 1.1.0. The dotnet migratecommand requires .NET Core CLI RC3 or higher.

Once finished, existing project.json and .xproj will be converted to .csproj. Depending on the project type, Rider will automatically reload the solution after migration completes (worst case, you may have to close and re-open Rider).
Further details on migrating projects from project.json to .csproj can be found on Microsoft’s documentation site:
