I don't know what to do here with this

My C# projects were all made using Visual Studio 2015. They run and open just fine with that version. Now I am experimenting with Visual Studio 2019 and when I tried to open a project a dialog box came up and said:

"Your project is targeting the .NET Framework 4.5.2 which is not installed on this machine. To proceed select an option below:

Change the target to .NET Framework 4.6.1. You can change back at a later time.

Download the targeting pack for .NET Framework 4.5.2. The project will not change.



So I don't know what to do. When I chose the Download the targeting pack... option it brought me to a page of SDK for Visual Studio. There are three listings under .NET/.NET Core. .NET 6.0, .NET 8.0, and .NET 9.0. Then there are a bunch of versions of the .NET Framework under .NET Framework. Here is what I was looking at:

.NET SDKs for Visual Studio

Find .NET SDKs for Visual Studio. Visit our main Downloads page for all .NET downloads, including Linux and macOS.

dotnet.microsoft.com

I do not have the foggiest idea of what to click on or install or anything.

It seems I made a similar thread awhile back. I absolutely don't remember doing that. But now I got to find the thread.

I think what I am going to try is change to VS 2022 and select .NET Framework 4.8 SDK.

4.8 is a good choice, 4.8.1 would be better.

This will give you a better perspective of choices for the classic .NET Framework versions:

Microsoft .NET Framework - Microsoft Lifecycle

Microsoft .NET Framework follows the Component Lifecycle Policy.
