Unity Visual Studio 2017 is throwing an error when build the project in VS, Error only in Oculus pac

Hi All,
I am getting this build error when i build the solution in visual studio(2017), but not throwing any error in unity(2019.2.1)  its because of the oculus VR package, in script also there are error lines but that is not affecting or showing error code in unity.

But while building its showing more than 200 errors in Visual studio console, any idea how to fix this?
Attached the reference image below:

Thanks
