## Enum Members

| Name | Value | Description |
| --- | --- | --- |
| Shared | 0 | Use a persistent Aspire-managed user data directory shared across all AppHosts on the machine. State such as cookies, sign-ins, and extensions persist across runs and are visible to every AppHost using the same browser. |
| Isolated | 1 | Use a persistent Aspire-managed user data directory scoped to the current AppHost project. Each AppHost gets its own state that persists across runs but is not shared with other AppHosts. |
