The isolated mode of Azure Functions with .NET allows for greater control over the runtime environment and dependencies of the function. In this mode, the function runs in its own process, separate from the Azure Functions host. This allows for custom runtime versions and specific versions of dependencies to be used.
This can be beneficial for certain functions that have specific performance or compatibility requirements.

This also applies to the Azure Function capabilities in Azure Web Apps and Static Web Apps.
