How to fix intellisense in Visual Studio Code

I just added a new project and started making changes but there is no intellisense or syntax highlighting, what is going on?

The solution is simple, you must add the new project to the Solution File (.SLN) for Visual Studio Code to recognize it!

dotnet sln add .\Scraper.UI\
Project `Scraper.UI\Scraper.UI.csproj` added to the solution.

Now, intellisense is working:
