Missing dependencies in new Visual Studio 2019 projects - visual-studio

Today I want to create a new project via Visual Studio 2019 Enterprise (V16.7.7). By default, the dependencies are missing:
I cannot start the Project via F5:
The Output Window shows 0 errors:
I can see the same behavior when I create a new Blazor-WA project.
I have re-installed the SDK (Microsoft .NET Core SDK v3.1.403) which not solves the problem.
How can I solve this problem?

Project configuration not showing in Visual studio 2019 (Xamarin)

I've opened my Xamarin Forms project (originally created in VS Mac) in Visual Studio 2019 on Windows.
I've got 3 Projects (App, App.iOS, App.Android). I had created some additional build configurations (Debug-Staging, Release-Staging and Debug-Prod, Release-Prod).
However, when opening in VS 2019, I can only see the standard Debug and Release configurations for the Shared App Project. (additional release configs seem to be there for the iOS and Android ones).
Any ideas how to resolve this?
If I click New and add Release-Prod, the dropdown for my shared project doesn't update..

How to Migrate Old Visual Studio Project to Visual Studio 2017?

Goal:
I try to open a visual studio project (c#) with CLR code for SQL Server from the Pluralsight course.
Issue:
I get no error messages just warnings below after One-way upgrade on Visual Studio 2017.
Your project is targeting .NET Framework 2.0 or 3.0. If your project
uses assemblies requiring a newer .NET Framework, your project will
fail to build. You can change the .NET Framework version by clicking
Properties on the project menu and then selecting a new version in the
'.NET Framework' dropdown box. (In Visual Basic, this is located on
the Compile tab by clicking the 'Advanced Compiler Options...'
button.)
When I open a solution with single project inside I get message below
The Project Needs to be migrated
or
The Project Needs to be loaded
Tried:
I tried editing csproj files with newer/older version numbers.
I tried different PCs with Visual Studio 2017 and Visual Studio 2015
Idea: Install Visual Studio 2010 as course was released in 2010 BUT I really do not want that.
When I got this issue, I tried reloading the project and when I did, it told me that I did not have an SDK installed and then it offered to install the SDK. Once I had the SDK installed, the project loaded and I was able to work with the project.

Visual Studio 2015 is unable to create a new Xamarin.Forms solution

After running into various stability problems with Xamarin in Visual Studio, I was recently forced to reinstall both Windows 10 and Visual Studio. In other words, my newly installed development environment is 100% clean and includes the latest updates to Windows 10 and the complete installation of Visual Studio 2015 Update 3. It also has the latest version of Xamarin for Visual Studio.
I was expecting that this would solve all my Xamarin problems, but it didn't.
Now, when I attempt to create a new Xamarin.Forms solution (Shared or PCL) it encounters this problem creating the Android project ...
... and this error creating all the other projects:
if I then try opening Package Manage Console, it fails to initialize with the following error:
The type initializer for 'System.Management.Automation.Runspaces.InitialSessionState' threw an exception.
Closing and re-opening Visual Studio allows Package Manage Console to initialize correctly, but then re-trying to create a Xamarin.Forms solution results in Visual Studio crashing while attempting to create the Android project:
Whilst I have never been impressed with the stability of Xamarin tooling, this is beyond a joke. I've already wasted 2 full days getting back to a completely clean Visual Studio environment and it still doesn't work.
Any ideas what I can do next? Thanks, in advance.

Updated Visual Studio 2015 RTM from Update 1 to Update 2, now Cordova Project is "Incompatible"

I updated my Visual Studio 2015 RTM from Update 1 to Update 2 and now my Cordova project won't open. I get the following error message instead of my project files:
This project is incompatible with the current edition of Visual
Studio.
I've installed the following hot fix and rebooted my machine and it made no difference:

The only option I get for that project is to edit my .jsproj file. But I haven't a clue what I'd have to change to make it work.
Here's my version info for Visual Studio:
How do I get my project to work with the new update to Visual Studio 2015?
For what ever reason, Visual Studio seemed to remove the Tools for Apache Cordova and I had to reinstall them from scratch. Once I'd reapplied version 8.1 of the tools, the project loaded up just fine.
