For the compatibility issue, .Net Core (6.0) and .Net Framework (4.5) are different animals, with .Net Core as more of a successor to Framework. They are very similar, but there are some breaking changes between Framework and Core, and if a project was intended for .Net Framework 4.5 you will want to have it installed on your system and set as the build target for the project in Visual Studio. You could probably also build for 4.7 or 4.8.
For the files, if they are part of the repo I would expect them to be there. I'd check your file system and see if the files are there, and then check the repo on github and see if they are included in the repo. If not, you may need an additional repo or you may need to manually add a NuGet package.
