在应用程序的依赖项$ c $中，我没有看到对您的库的引用c>部分。如果您的库和应用程序在同一个解决方案中，请确保使用 target：project 像这样：

I didn't see a reference to your library in your application's dependencies section. If your library and your application are in the same solution, make sure you use target: project like so:

ASP.NET Core项目的 project.json ：

project.json of ASP.NET Core project:

"dependencies": {
    ...
    "MyLibrary": {
        "version": "1.0.0",
        "target": "project"
    }
}

否则，NuGet会将您的库作为软件包查找，而不是在解决方案中查找。

Otherwise, NuGet will look for your library as a package instead of looking in the solution.
