Error: Your project is not referencing the "MonoAndroid, Version = v8.1" framework

After updating Visual Studio to version 15.7.1 the following message began to appear in my ready projects:

  

Your project is not referencing the "MonoAndroid, Version = v8.1"   framework. Add a reference to "MonoAndroid, Version = v8.1" in the   "frameworks" section of your project.json, and then re-run NuGet   restore

If you create a new project this does not happen, I would like to know how I could solve it, I could not.

I have tried to Clean / Restore Solution and Restore NuGet Packages.
