dotnet new -i sqlsugar.template
dotnet new --list
以上我们的项目模板就安装好了，现在我们来使用模板
用CMD进入你的工作目录，如：D:\test
执行命令：
dotnet new sqlsugartemplate -n YXY.Member
sqlsugartemplate：是模板的名称
YXY.Member：是你想定义的项目名称
以上项目的模板创建成功了，这里需要创建项目的解决方案工程文件
此时进入项目的目录，执行命令
cd YXY.Member
添加项目的解决方案
dotnet new sln -n YXY.Member
dotnet sln YXY.Member.sln add YXY.Member
dotnet sln YXY.Member.sln add YXY.Member.Contracts
dotnet sln YXY.Member.sln add YXY.Member.Extensions
dotnet sln YXY.Member.sln add YXY.Member.Models
dotnet sln YXY.Member.sln add YXY.Member.Repository
dotnet sln YXY.Member.sln add YXY.Member.Service
以上整个项目模板创建成功了，可以正常使用了，打开项目解决方案即可运行。
