No project was found. Change the current working directory or use the --project option

No project was found. Change the current working directory or use the --project option

　　执行dotnet ef migrations createmodel、dotnet ef migrations add initial等命令出错，报错信息为：No project was found. Change the current working directory or use the --project option.命令出错。个人百度.net core、dotnet ef migrations createmodel、dotnet ef migrations add initial、No project was found. Change the current working directory or use the --project option关键字都未发现这个问题的解决办法，最后使用必应国内版，搜索No project was found. Change the current working directory or use the --project option.关键字，得到了解决办法。

　　第一种：dotnet ef migrations add InitialCreate --project="C:\path_to_my_project\MyProject.csproj"   使用这样的命令操作，在我写的代码没有作用，依然报出之前的问题；

　　第二种：PM> cd "D:{path_to_your_projet}"  PM> dotnet ef migrations add initial 使用第二种方法解决了，不可以使用dotnet ef migrations createmodel、dotnet ef migrations add initial命令的问题。
