I'm new to this area, I'm "walking barefoot on the rocks" to learn ASP.NET, I use the VISUAL STUDIO 2017 Community 2017 Version 15.8.4.
When creating a new ASP.NET MVC project visual studio generates an empty application with a menu.
When upgrading packages via the Package Manager Console, this application loses its menu and its features.
I believe it's because of the Bootstrap update and other scripts.
I confess that I'm in the dark without the template that ASP.NET MVC creates to guide me, I've already seen on the Bootstrap site that the current version is 4.1. Already in the template created with ASP.NET MVC the version is 3.3.7. That is, can not update the packages of the created template?
Has anyone ever experienced this, missing the page format because of this?
I have already researched several models and examples, but all I found are based on older versions, the models on the Bootstrap site are very different.
My lack of experience tells me that I must have the answer, but I do not know how to interpret it.
From now on, I thank the friends who can give me a direction to follow ...
