Thanks for your request. We have
just released a new version of Aspose.Words. The main feature in Aspose.Words
for .NET 5.0.0 is load and save of DOCX documents reaching its Release status.
So please try using this version.
The new version of Aspose.Words is available for download from here.
Note that Full support for Content Controls will be available later,
hopefully in March.
Also note that there are two different ways images and shapes can
be included in OOXML documents: VML and DrawingML. VML images and shapes are
supported by Aspose.Words in DOCX files. However, DrawingML is not yet
supported. We are still working on DOCX import and that includes supporting
DrawingML. I think full support for DrawingML will come out in March.
