You need to Dispose of disposable objects like streams in order to free up the resources they're using.

When you set the PdfSource property to null, you throw the stream away without disposing of it. You have to wait for a GC cycle to detect that it's no longer referenced and "finalize" it.

Change your code to dispose of the existing stream (if any). For example:
C#
public Stream PdfSource
{
    get { return _pdfSource; }
    set
    {
        if (ReferenceEquals(value, _pdfSource)) return;
        if (_pdfSource != null) _pdfSource.Dispose();
        SetProperty(ref _pdfSource, value);
    }
}
