In the package manager console, make sure to select the default project.
在包管理器控制台中，确保选择默认项目。
If there are no choices, it means that there is no solution file created for your project. When I tested this, I was able to fix the problem by pressing Ctrl + Shift + S (Save all). Visual studio then prompted me to select a directory for my .slnfile and NuGet then successfully recognized my solution/project.
如果没有选择，则意味着没有为您的项目创建解决方案文件。当我对此进行测试时，我能够通过按 Ctrl + Shift + S（全部保存）来解决问题。Visual Studio 然后提示我为我的.sln文件选择一个目录，然后 NuGet 成功识别我的解决方案/项目。

Just like Farshid said, it means that there is no solution file created for your project and in order to fix this, press Ctrl + Shift + S. Visual studio will prompt you to select a directory for your .sln file which will in turn make NuGet recognize your solution.
就像 Farshid 所说的那样，这意味着没有为您的项目创建解决方案文件，为了解决这个问题，请按 Ctrl + Shift + S。Visual Studio 将提示您为 .sln 文件选择一个目录，这将依次使NuGet 识别您的解决方案。
