@simoncropp,
Our developers have investigated the case. You should use extern alias for Aspose.Slides.

Hello,

is the “external alias”-suggestion only valid for the current version or is it supposed to stay the same in future versions?

@AndreN,
The issue is not related to Aspose.Slides directly because there may be two other libraries with the same issue. This is a C# mechanism used when two versions of assemblies with the same fully-qualified type names are added to your project. Therefore, it should also remain the same for future versions of Aspose.Slides for the case.
