The error message you're encountering (10.2.4.1 Security - Software Dependencies) indicates that the Microsoft Store review process flagged your .NET MAUI Blazor application (updated from 6.0 to 8.0) because it likely depends on external software that isn't directly included in your MSIX package.
To address this issue and ensure compliance with the Microsoft Store requirements, you need to clearly mention any dependencies, including the .NET runtime, within the first two lines of your app's description.
Here's an example of how you can modify your app's description to comply with this requirement:
[Your App Name]
[Short description of your app]
Dependencies: This app requires the .NET runtime for operation.
Refer to the Microsoft documentation on MSIX package requirements and dependencies: https://learn.microsoft.com/en-us/windows/msix/
