error CS0246, even though assembly is in references and got correct using directive

error CS0246, even though assembly is in references and got correct using directive.

How can I resolve these issues with VideoOS.Platform and more VideoOS references? Everything looks right.

My current code:

if (maybeUserItem.HasChildren != VideoOS.Platform.HasChildren.No)
{
    // ...
}

We tested with the snippet of code you shared, but we could not reproduce. We also added the references that you showed but no luck reproducing.

Could you please tell us how to reproduce this one? Are some special settings required?

Pls please tell us which version of the Visual Studio and MIP SDK you are using?
