| Drawback | Mitigation Strategy | |--------------------------------|------------------------------------------------------------| | Runtime may be missing | Use the bootstrapper to install silently on demand. | | Network dependency | Fallback to Fixed Version for air-gapped/offline systems. | | Breaking API changes | Microsoft guarantees API compatibility; test against preview runtimes. | | Version skew | Use EnvironmentOptions.TargetCompatibleBrowserVersion to request a minimum version. | | Corrupted runtime | Detect failure and prompt repair via runtime installer. |

| Feature | Evergreen WebView2 | Fixed Version WebView2 | | :--- | :--- | :--- | | Update cadence | Automatic, frequent (roughly every 4-6 weeks) | Developer-controlled; you ship a specific version | | Disk footprint | Shared (one copy per machine) | Per-app (each app bundles its own runtime) | | Network bandwidth | One download for all apps | Each app downloads its own copy | | Security model | Always patched | You must republish to patch | | Best for | Most line-of-business apps, public-facing apps | Air-gapped, appliance-like, or strict version control scenarios |
