Right now the Telerik UI MVC NuGet package is a 30 MB package that installs not just the DLL, but a lot of boilerplate JavaScript and CSS. I prefer to acquire the necessary content via Bower, so I can only install what I need. Currently, after every upgrade I have to wait for the package to install, then delete all of the unused content files. It would be nice if you supplied an "assembly-only" package, moving the content into an optional package that users who still need it could install. It would reduce upgrade time substantially, as well as offer less chance for a mistake.
Not sure if this is a valid workaround, but I manually added the package reference to my project (as opposed to using the NuGet CLI/UI.
<ItemGroup>
<PackageReference Include="Telerik.UI.for.AspNet.Mvc5" Version="2021.2.616" >
<ExcludeAssets>contentFiles</ExcludeAssets>
<PrivateAssets>contentFiles</PrivateAssets>
</PackageReference>
</ItemGroup>
