Aspose.Total on Asp.NET 5 and .NET CORE (CrossPlatform)


Thanks for contacting support.

The product teams are working on creating APIs based on .NET core but I am afraid they are not yet available. We do understand the necessary of this requirement but I am afraid the teams have been busy supporting other previously requested high priority requirements and fixing some critical issues. Nevertheless, as shared earlier, we can share some updates by Q1-2018.

Please be patient and spare us little time.

Is there a beta release cycle that users can apply for before RTM?


Once the .NET core is supported, then we would be able to share the Hotfix versions of the Aspose APIs. Normally, we release a new version of each Aspose API in a month, and share a Hotfix version if the full version is taking time to come out. It is a complex task because we need to remove some dependencies to add support of .NET Core. We will let you know once a significant progress has been made in this regard.

@F_Z_14, @lars.olsson, @craigfis, @rsamveda.ramsoft, @MaitreDede, @Shrike, @gwert, @michaelhelfenstein, @sandcastle,
