Conversation
Two ASP.NET Core samples demonstrating server-side token proxy patterns for hosting the Genetec Web Player: - GwpMinimalApiSample: single Program.cs with static HTML page - GwpRazorPagesSample: Razor Pages with per-request CSP nonces and server-rendered configuration via JsonSerializer.Serialize Both samples include proper player lifecycle cleanup on failed start and cancellable startup with generation tracking.
The limitation is that the application itself has no user authentication, not just the token endpoint.

Pull request overview
Adds two new ASP.NET Core hosting samples for Genetec Web Player (GWP): a Minimal API static-site sample and a Razor Pages sample that demonstrates per-request CSP nonces while proxying Media Gateway token requests server-side.
Changes:
- Introduces GwpMinimalApiSample (static
index.html+/api/configand/api/token/{cameraId}endpoints). - Introduces GwpRazorPagesSample (Razor page with server-rendered config + CSP nonce middleware +
/api/token/{cameraId}endpoint). - Adds sample documentation and local debug profiles (
launchSettings.json) for both.

The CSP policy allows https: in default-src and script-src, which permits scripts (and other resources via default-src) to load from any HTTPS origin. If the goal is to tighten CSP, consider restricting sources to the configured Media Gateway origin (and/or setting a nonce on the dynamically injected gwp.js script) instead of using the broad scheme source.

| ### 2. Allow the page origin in Media Gateway CORS | ||
|
|
||
| If strict CORS is enabled, add the ASP.NET application origin to `MediaGateway.gconfig`: | ||
|
|
||
| ```xml | ||
| <?xml version="1.0" encoding="UTF-8"?> | ||
| <Configuration> | ||
| <MediaGateway EnforceStrictCrossOrigin="true"> | ||
| <AllowedOrigin Origin="https://localhost:5001" /> | ||
| </MediaGateway> |

The CORS example hard-codes https://localhost:5001, but this sample’s launchSettings.json uses different default ports. Consider updating the snippet/text to tell readers to use the actual origin printed on the page/console output (or match the configured applicationUrl) to avoid confusion.
