✅ Output TaskParameter is unrecognized

I'm trying to use CreateItem to add metadata to an item using batching, but it says that

error MSB4066: The attribute "TaskParameter" in element <Output> is unrecognized.

error MSB4066: The attribute "TaskParameter" in element <Output> is unrecognized.

Code that throws:

<CreateItem Include="@(_ResolvedProjectReferencePaths)" AdditionalMetadata="ProjectPath=%(OriginalItemSpec)" Condition="'@(_ResolvedProjectReferencePaths)'!=''">
    <Output TaskParameter="Include" ItemName="TmpResolvedProjects" />
</CreateItem>

<CreateItem Include="@(_ResolvedProjectReferencePaths)" AdditionalMetadata="ProjectPath=%(OriginalItemSpec)" Condition="'@(_ResolvedProjectReferencePaths)'!=''">
    <Output TaskParameter="Include" ItemName="TmpResolvedProjects" />
</CreateItem>

you should not use CreateItem. it is deprecated you should use ItemDefinitionGroup instead

<ItemDefinitionGroup>
    <_ResolvedProjectReferencePaths>
        <ProjectPath>%(OriginalItemSpec)</ProjectPath>
    </_ResolvedProjectReferencePaths>
</ItemDefinitionGroup>

<ItemDefinitionGroup>
    <_ResolvedProjectReferencePaths>
        <ProjectPath>%(OriginalItemSpec)</ProjectPath>
    </_ResolvedProjectReferencePaths>
</ItemDefinitionGroup>

as an aside, this code seems extremely sus

it's probably not the best or correct way to do what I want I have a list of items with a ProjectPath metadata (that then gets converted to a ProjectReference), and I want to filter _ResolvedProjectReferencePaths to only those that exist in my list (so that I can then get the referenced projects' compiled dll file) I found this (https://stackoverflow.com/questions/42403046/msbuild-itemgroup-intersection) and this (https://learn.microsoft.com/en-us/archive/blogs/msbuild/batching-brainteaser-explained) to get the intersecting items, but I have the issue with CreateItem

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.

Bump I decided to just pass the @(_ResolvedProjectReferencePaths) to a custom task and then do the filtering I need there
