Why does the .net core VkNet project not compile?

Question

C++ / C#

Good afternoon!
Faced with the fact that I need to modify the popular VkNet library https://github.com/vknet/vk. I downloaded the project and immediately see a lot of errors that prevent compilation. As far as I understand, this is a .net core project, and I haven’t worked with core before, but it’s strange that the project immediately has a lot of compilation errors. Most likely I didn't connect something? Tell me what could be wrong

Answer 1

No, this is not a Net core project. This is a netstandard project. At me it is going normally right after loading. The master branch of the latest version.
Try installing the latest SDKs for .Net framework and for .Net Core and Dev-packs https://www.microsoft.com/net/download/visual-stud...
