Hey @AHuusom.
Please take a look at the comment - #4424 (comment)

Our recommendation is always to use tasks to install .Net in runtime:

1. UseDotNet@2 - Azure DevOps
2. setup-dotnet - GitHub

@al-cheb - that doesn't align at all with what was done for the Ubuntu, Mac, and windows-2022 images - all of which have .NET 6.0.401 now. It's only windows-2019 that doesn't. Why should it be any different?

Also, the Support Policy says explicitly that .NET Core will have the installation strategy of:

"2 latest LTS versions and 1 latest version. For each feature version only latest patch is installed"

The windows-2019 image is getting .NET 5 installed, which is out of support. .NET 6 and 3.1 are the two LTS versions.
