Installation of ASP.NET Core 3.0 with Troubleshooting

Before starting ASP.NET Core 3.0 tutorial you need to configure your PC with Core 3.0 Framework. In this tutorial, I will teach you how to configure your PC with Core 3.0

You need to install Visual Studio 2022 with Update 3. You can download Visual Studios 2022 and It's update from the Microsoft's site. The quick link is given below:
Type: Offline Installer (.ISO)

If you have already installed Visual Studio 2022 then you need to just install Update 3. You can find Visual Studio 2022 Update 3 at here.
Type: Offline Installer (.ISO)
Size is Approx 6GB.

After Downloading Visual Studio 2022 Community Edition (Because it is Free) with Update 3, Install it in your PC. Minimum requirements to install this software are as follow:
  1. OS: Windows 7 with service pack 1, Windows 8/8.0/10, Windows Server 2012, 2012 R2 and 2008 R2 SP1

Installation is very easy and you won't get any trouble. However, you will get some warnings or errors regarding Microsoft Visual C++ Redistributable file. Don’t get panic. All the redistributable files are freely available over the internet and it is light weight (Under 5MB). Find, download and Install them.

After installing Visual Studio 2022 Community Edition with Update 3, your PC is ready to install .Net Core 3.0 Framework. You can download .Net Core 3.0 from Here.

However, I couldn’t find offline installer of .Net Core 3.0 so it is web installer but you may find it. You need to internet connection while installing .net core.
