Hi,
I'm trying to addProjectReference orPackageReference on a condition with a target. I have csproj files including these:

<CustomReferenceInclude="Package1" /><CustomReferenceInclude="Package2" />

The condition property is set inDirectory.Build.props:

<PropertyGroup>  <UseLocalNuGetProjectsCondition="'$(UseLocalNuGetProjects)' == ''">true</UseLocalNuGetProjects>

And the target is implemented inDirectory.Build.targets :

<Project>  <TargetName="ResolveCustomeReferences"BeforeTargets="BeforeBuild;ResolveReferences">    <ItemGroupCondition="'@(CustomReference.Identity)' != ''">      <MSBuildProjects="$(MSBuildThisFileDirectory)Libraries/%(CustomReference.Identity)/%(CustomReference.Identity).csproj"Targets="Restore;Build"Condition="'$(UseLocalNuGetProjects)' == 'true'" />      <ProjectReferenceInclude="$(MSBuildThisFileDirectory)Libraries/%(CustomReference.Identity)/%(CustomReference.Identity).csproj"Condition="'$(UseLocalNuGetProjects)' == 'true'"IncludeAssets="all" />            <PackageReferenceInclude="@(CustomReference)"Condition="'$(UseLocalNuGetProjects)' != 'true'" /><!-- I have also Directory.Packages.props so I don't need version in PackageReference in the target.-->    </ItemGroup>  </Target></Project>

I have 2 problem with this approach:

1. The build is working if the project doesn't use transitive nuget packages in the referenced project withProjectReference. If the project uses nuget packages included in the referenced project withProjectReference, then build fails. Normally, if we setProjectReference statically in the csproj, we can use transitive nuget packages in that reference, but I couldn't overcome the unresolved nuget package errors with above dynamically addedProjectReference.
2. The intellisense and solution explorer doesn't see theProjectReference norPackageReference according toUseLocalNuGetProjects property.

How can I solve these two problems?

By the way I've tried many targets inBeforeTargets likeResolveProjectReferencesDesignTime2,CompileDesignTime,ResolveProjectReferences,ResolvePackageDependencies,Compile, etc, but no luck.

Best Regards.
