I wasn't able to reproduce the issue.
I installed the v2.0.2 product, built and ran the examples without any issues using VS 2017.
I didn't make any changes to the projects and I didn't updates any of the project dependencies.
Below is a screenshot of the installed packages.
Various updates are available by I didn't update any of the packages.
Please see if you can build and run the ExampleIdentityProvider and ExampleServiceProvider projects.
