### Describe the solution you'd like

Since #20946 is locked (which I [personally find annoying](https://github.com/dotnet/runtime/issues/68740)), here's some additional information that might interest people in the original thread (@hansmbakker,@Tratcher, @ryanelian, @BrennanConroy). It will also probably help people stumbling on this issue in the future.

After a 5 years pause, the [Microsoft.AspNetCore.WebUtilities](https://www.nuget.org/packages/Microsoft.AspNetCore.WebUtilities/8.0.6) NuGet package has been published again. It is now targeting `net8.0` and enables using `QueryHelpers` outside of ASP.NET Core.
