Can't find reference to SQLXML in Visual Studio 2005 SSIS Package -

I had a project that I was working in Visual Studio 2008, when requirements changed and now it was done in 2005. I was using the SQLXML object from Microsoft.Data.SqlXml, but now when I was downgraded I could not find it in the pop-up box in the context of adding it.

Does anyone know why this is not showing and how can I show it? I tried to uninstall and reinstall SQLX and updated SP3 from VS2005

thanks

Then it should look like when you go to add context.
