If [ResourceUrlsCallbackContext.Resource](/reference/api/csharp/aspire.hosting/resourceurlscallbackcontext/properties.md#resource) does not implement [IResourceWithEndpoints](/reference/api/csharp/aspire.hosting/iresourcewithendpoints.md) then returns `null`.
- [GetEndpoint(string, NetworkIdentifier)](/reference/api/csharp/aspire.hosting/resourceurlscallbackcontext/methods.md#getendpoint-string-networkidentifier) : [EndpointReference?](/reference/api/csharp/aspire.hosting/endpointreference.md) -- Gets an endpoint reference from [ResourceUrlsCallbackContext.Resource](/reference/api/csharp/aspire.hosting/resourceurlscallbackcontext/properties.md#resource) for the specified endpoint name. If [ResourceUrlsCallbackContext.Resource](/reference/api/csharp/aspire.hosting/resourceurlscallbackcontext/properties.md#resource) does not implement [IResourceWithEndpoints](/reference/api/csharp/aspire.hosting/iresourcewithendpoints.md) then returns `null`.
