Issue:

D:\a\_work\1\s\.dotnet\sdk\10.0.100-preview.4.25177.22\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(266,5): error NETSDK1047: Assets file 'D:\a\_work\1\s\src\aspnetcore\artifacts\obj\Microsoft.AspNetCore.Runtime.SiteExtension\project.assets.json' doesn't have a target for 'net462/win-x86'. Ensure that restore has run and that you have included 'net462' in the TargetFrameworks for your project. You may also need to include 'win-x86' in your project's RuntimeIdentifiers.

@joperezr we may be able to make this work by resetting IntermediateOutputPath or BaseIntermediateOutputPath before the project.assets.json file gets defaulted.
