Visual Studio 2019 - change .NET target framework to 4.8-CodePudding

I cannot change the .NET version of my project. I installed .NET 4.8 via the Visual studio installer and manually downloaded it separately. Neither of these works.

I actually tried to change the framework in the .csproj project file

<TargetFramework> net5.0-windows </TargetFramework>

<TargetFramework>net48</TargetFramework>

and it doesn't work too... I'm running out of solutions and don't really know what to do next.

CodePudding user response：

Have you tried to add .net 4.8 component to VS2019?

CodePudding user response：

If you're attempting to convert an SDK-style "net5.0-windows" project to a "net48" WinForms one you'll likely need to do more than just change TargetFramework.

Firstly, the Project node at the start of the ".csproj" file should look like this:

<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop">

(A "net5.0" target doesn't need the .WindowsDesktop part of that.)

Secondly, you'll need to ensure that <UseWindowsForms>true</UseWindowsForms> is part of the main PropertyGroup.
