MS Visual Studio 2019 - CRASH when Adding a new Scaffolding item

I'm trying to build an ASP.NET Core Web application .NET Core 3.1.
I run MS Visual Studio 2019, latest build.
I created the "Controllers" folder, an error occurs when trying to add Controller:
Error: there was an error running the selected code generator package restore failed
API Controller empty.
To resolve the issue, I tried the following to no avail:
Delete folders .vs, bin, obj
Clean and Rebuild project
Clear all NuGet caches
Restart, reboot
For what I can find it seems related to:
Error NU1202. Package Microsoft.AspNetCore.Razor 2.2.0 is not compatible with netcoreapp3.1 (.NETCoreApp,Version=v3.1). Package Microsoft.AspNetCore.Razor 2.2.0 does not support any target frameworks.
How can I solve the problem?
Resolved installing latest Visual Studio updates

"The build task could not find node.exe which is required to run the TypeScript compiler." occurred after update Boostrap

I developed an ASP.Net MVC web application and It's almost completed. After That, I updated Bootstrap through NuGet package manager to Bootstrap latest stable version 4.3.1 Update was successfully completed. But after the migration following errors are occurred.
Error Build:Cannot find name 'Record'.
Error Build:Cannot find name 'undefined'.
To solve that I installed TypeScript for Visual Studio 2015. Then the above error solved and the following error occurred.
Severity Code Description Project File Line Suppression State
Error The build task could not find node.exe which is required to run
the TypeScript compiler. Please install Node and ensure that the
system path contains its location. ABH.SW.HotelManagement
How can I solve this? I tried to google it for the past 2 days but I wasn't able to find any solution
This is the only post for this problem, so I'll do my bit for those who use Bootstrap 4.3.1, TypeScript, and VS2015.
First, once you create the project and are about to install Bootstrap 4.3.1 through NuGet, don't let Visual Studio manage TypeScript Typings for you. Check no.
Once Bootstrap and stuff is installed, clean the solution: right click on your solution -> clean solution
Next, open NuGet console (Tools → NuGet Package Manager → Package Manager Console), and install TypeScript 3.0 using this command:
Install-Package Microsoft.TypeScript.MSBuild -Version 3.0.0
Close Visual Studio, open it again, and that's it. Took for me a lot of research to find out that several TypeScript versions cause a lot of conflicts and 3.0 is one of those that actually work.
I had the same issue while trying to update to Bootstrap 4 from Visual Studio 2015. What fixed it for me was installing Typescript 2.2 for Visual Studio 2015 (https://marketplace.visualstudio.com/items?itemName=TypeScriptTeam.TypeScript22forVisualStudio2015). You may need to uninstall previous versions of Typescript Tools for VS2015 from Programs and Features.
I think Bootstrap 4.3.1 , Typescript , VS2015 has some issues with each other.
[e.g.
Compilation error from Angular and typescript in VS 2015 MVC project
]
My scenario in my project got this error
Error The build task could not find node.exe which is required to run
the TypeScript compiler. Please install Node and ensure that the
system path contains its location. ACC_Cor...
I'm using VS2017 while other team member that has problem using VS2015 with TypeScript Tools for Microsoft Visual Studio 2015 3.2.2.0 installed
He told me that after map project from source control there is and alert message of something like his typescript version is newer. So after some googling I think you should look in to this link for more information
https://github.com/Microsoft/TypeScript/issues/17136
VS2015 - Change TypeScript Version
How to run TypeScript in Visual Studio 2015 without require() or requireJS
tldr;
For Vs2015 + Bootstrap 4.3.1 I solved my issue by
Check project property
Uninstall Typescript
Install Typescript version 3.0 https://www.microsoft.com/en-us/download/details.aspx?id=48593

Asp .Net Core - cannot install Microsoft.AspNet.Mvc nuget package

In my Asp .Net Core Web Application (started with empty template) I cannot install Microsoft.AspNet.Mvc nuget package.
After pressing Install in Nuget manager I get this error message:
Package restore failed. Rolling back package changes for 'WebApplication1'.
I tried to solve it on my own, but:
1) My project doesn't have project.json
2) Clearing nuget cache like in this answer didn't help:
Netstandard1.x Nuget packages cannot be installed for netstandard1.x projects
Project target framework: .NetCoreApp1.0 (also tried 1.1)
Ide: VS2017 RC
I didn't have problems so far with installing other packages.
Is there a workaround to install mvc package?
Btw. I have to start with empty project template.
Thanks in advance for your support.
I looked harder in nuget package name and discovered that correct package to install should be Microsoft.AspNetCore.Mvc and not Microsoft.AspNet.Mvc.
Silly mistake, I chose most popular package by typing "mvc" in search box.

xunit.core is incompatible with version of NuGet

I added a new project to the solution. I've added some nuget packages however it fails when building on TFS. It works fine when building locally. I get the following error messages:
C:\Builds\8\Server-Dev-CI\src\.nuget\NuGet.targets (58): The schema version of 'xunit.core' is incompatible with version 2.0.30828.5 of NuGet. Please upgrade NuGet to the latest version from http://go.microsoft.com/fwlink/?LinkId=213942.
C:\Builds\8\Server-Dev-CI\src\.nuget\NuGet.targets (58): The schema version of 'xunit.extensibility.execution' is incompatible with version 2.0.30828.5 of NuGet. Please upgrade NuGet to the latest version from http://go.microsoft.com/fwlink/?LinkId=213942.
C:\Builds\8\Server-Dev-CI\src\.nuget\NuGet.targets (58): One or more errors occurred.
C:\Builds\8\Server-Dev-CI\src\.nuget\NuGet.targets (58): The command ""C:\Builds\8\Server-Dev-CI\src\.nuget\nuget.exe" install "C:\Builds\8\Server-Dev-CI\src\Modules\UnitTests.xUnit\packages.config" -source "https://nuget.org/api/v2/" -o "C:\Builds\8\Server-Dev-CI\src\packages"" exited with code 1.
When I open the sources in VS2013 (on the build server) I see the following:
I have to click Restore Packages to get it to work.
I already updated NuGet. Where is it getting " 2.0.30828.5 of NuGet" from???
I figured it out. The whole time I though TFS uses Visual Studio's NuGet, however it turns out TFS runs:
C:\Program Files\Microsoft Team Foundation Server 12.0\Tools\nuget.exe restore
I had to open up console and update nuget:
nuget.exe update -self

Can not install SignalR client nuget package for MonoDroid

I was trying to install Nuget package for MonoDroid project (Visual Studio 2015):
Microsoft.AspNet.SignalR.Client
And I got this error:
Could not install package 'Microsoft.AspNet.SignalR.Client 2.2.0'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v4.3', but the package does not contain any assembly references or content files that are compatible with that framework.
Any idea to sort this out?
