I recently installed versions of .net core sdk 3.1 and 5. When using the .net5 version today, I found that I couldn't select the version when I created the project, only version 3.1. So I opened the terminal and entered the command: dotnet --list-sdks to query all my installed versions and found that only 3.1.405[C:\Program Files\dotnet\sdks] is displayed. What is the reason for this? I'm sure I have the sdk for .net5 installed. I got it from this site.

The issue might relates the Visual Studio version. From the Asp.net core document and the SDK download page, we can see that to use Asp.net 5, it required Visual Studio 2019 16.8 or later version:
So, you can upgrade the VS 2019 version to Visual Studio 2019 16.11.9 version or Visual Studio 2022, and then in the Visual Studio Installer click the "Modify" button on the installed Visual Studio, in the popup window, go to the Individual components panel, checked the .NET 5.0 runtime option:
Then when create new applications using Visual Studio, you can choose the .Net 5.0 version.

I am having issues while creating a project, it didn't show .Net framework 4.8. But I have already installed it. .Net SDK also installed.
When I check Programs and features in control panel, there is no source of Microsoft .Net framework 4.8. But it is showing .Net framework 7.0 and other versions.
After that I checked in Registry editor Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full there it is showing 4.8 version. But its not showing in Visual studio 2022.
Tried with some solutions through google and youtube. There is no use
Currently I am using Visual studio 2017 and it that asp.net core. In that there is showing version asp.net core 2.1.
But this is not the latest version for using asp.net core 2.1. So how can I want to use in asp.net core 2.2 in existing visual studio, which is 2017
Shorten Answer:
Suggest you using official website to download ASP.NET Core SDKs and then run the downloaded file to install the SDK. Relaunch the Visual Studio and create a Web Application and then you'll find the ASP.NET Core 2.2.
From the release notes said Visual Studio 2017 support sdk version is end with SDK 2.2.106. Begin with SDK 2.2.203, you need use Visual Studio 2019 version 16.0. So Visual Studio 2017 does not support the latest version of ASP.NET Core 2.2. The latest version that Visual Studio 2017 can download is 2.2.106(Runtime version is 2.2.4).
Besides, the official document does not emphasize the Visual Studio 2017 specific version, it is better to use the latest version. Because if the Visual Stuidio version does not match the SDK version, it will not display ASP.NET Core 2.2 when you create a web application.
For example:
For my 64-bit version of Windows, I will choose the following link to download the sdk:
Note:
ASP.NET Core current release version is .NET 7 preview 1, ASP.NET Core 2.2 is actually an old version.
I create a project as per the screenshots and the following error appears when I try to Build or Run.
Error MSB3644 The reference assemblies for .NETFramework,Version=v5.0 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application. You can download .NET Framework Developer Packs at https://aka.ms/msbuild/developerpacks WebApplication1 C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets 1177
Below is my about screen, shouldn't show with Net Version 5.0 as opposed to Version 4.8.03752?

It states that my NET version was part of my Visual Studio 2019 (16.3 update)
.NET 5 is actually .NET Core 5 and replaces .NET 4.x. New development continues on the .NET Core line only. .NET Old will only get fixes from now on. That's why you won't see any .NET Old versions beyond 4.8 in Visual Studio.
.NET 5 is supported in the latest Visual Studio version, 16.8. You need to upgrade to the latest version. The final of both .NET 5 and Visual Studio 16.8 were released yesterday during dotNETConf 2020. You can find the first day's sessions in .NET's YouTube channel.
The sessions explain what .NET 5 is, what's new, how to port existing applications from .NET Framework 4.x to .NET 5 including desktop applications like Windows Forms and WPF applications.
Some early .NET 5 previews were supported in 16.7 but the latest previews and RC versions were only supported on 16.8
I have installed Visual Studio 2017 Community Version 15.7.5 2 days back and everything is up-to-date but the version of ASP.Net Core is 2.0 and I need it to be 2.1.
I am unable to find a way to update it to version 2.1. I have also searched the internet but there are ways to upgrade projects not to update this. So any ideas or help would be appreciated
It looks like the SDK for .NET Core 2.1 is not installed. I have recently faced the same issue after .NET Core 2.1 was released.
To solve it, download and install the SDK for .NET Core 2.1 following the steps below. Also, note that you need to run Visual Studio 2017 15.7 or newer version, as specified in the .NET Core 2.1 download page.
Close all running Visual Studio instances.
Download the .NET Core SDK from the Microsoft download page. At the time of writing this answer, you will find version 2.1 to be the latest available.
Run the installer and follow the installation steps.
Run Visual Studio: now you should be able to create .NET Core applications targeting version 2.1.
After installing .NET Core 1.1.0 - SDK 1.0.0 Preview in Visual Studio 2015 community update 3, I don't see .Net Core template
I uninstalled the previous Visual Studio 2015 community update 3 and .Net Core 1.0 with TotalUninstaller tool from Git. The uninstall process was successful.
Then I've reinstalled Visual Studio 2015 community update 3 and .NET Core 1.1.0 - SDK 1.0.0 Preview. When I create a new project, I don't see .Net Core in the templates. I also have Web Developer Tools installed. I've followed advises on other blogs Am I missing something? Thanks.
