Published Blazor WASM App unable to load Workbook

Aspose.Cells Product Family

Getting the following error when I attempt to use the latest Aspose.Cells Nuget package in a published Blazor WASM App. Please see the attached Solution for a reproducible case.

NOTE: You will need to emulate an Azure Static Web App using the following instructions to see the issue.

The error is visible with a simple folder publish and using the SWA Docker container to test it.

Also visible when publishing to an Azure static web site

HI @John.He ,

Thanks for the update. I work on the same team as jfield. We’re hoping to release a product at the end of the month using Aspose in a Blazor WASM app. This is currently a major blocker. Any help in prioritizing this would be great.

@xinya.zhu,

We have a paid support plan, but often prefer to log cases in the forums for the benefit of other customers. I will look into out support portal and formally request priority support for this issue, if its possible. We reserve that request for when we need it, and this is one of those situations.

We appreciate your quick responses.
Thank You,
-Andy
