Install nuget windows forms package for using chart in .Net 5

Using vs 2019, I locally installed the NuGet package "system.windows.forms.datavisualization.1.0.0-prerelease.20110.1.nupkg" from Microsoft to use the Windows Forms chart function under .NET 5.The Solution explorer > Manage NutGet packages shows that it's successfully installed. Also dependencies indicates that the package is installed.When trying to use now the a chart, the toolbox doesn't show any chart options under "Data". Why couldn't I find the "chart function" although the package is successfully installed and shows no errors or warnings .. ?
