Answer 1

Trevor answer worked for me, but there is alternative solution.

I've noticed that this missing class Microsoft.Extensions.Primitives.DateTimeFormatter was removed from Microsoft.Extensions.Primitives dll in version 4.0. Some of dependencies to my project required version >=3.2 and some >=5.0. I guess linker chosen to link higher 5.0 version so the other dependency failed to find removed class.

Solution is to update all dependencies so their dependencies uses versions of Microsoft.Extensions.Primitives >=5.0
