Could not recreate all objects.

Error message

Could not recreate all objects.

What it means

ResumeManager.OnRecreate re-creates graphics resources after a device reset/context resume. If some resources were destroyed and could not be recreated, it throws InvalidOperationException with a 'DestroyedObjects' entry in Data listing the resources stuck in the Destroyed lifetime state.

Solutions

1. Inspect the exception's Data["DestroyedObjects"] list to identify which resources failed to recreate
2. Fix the recreation path of the failing resources (e.g. unsupported format/size after device reset)
3. Dispose and rebuild the GraphicsDevice or reload the affected assets if resources cannot be restored
4. Handle device-lost events gracefully so recreation retries with valid parameters

Example fix

// before
catch (InvalidOperationException) { /* ignored */ }
// after
catch (InvalidOperationException ex) when (ex.Data.Contains("DestroyedObjects"))
{
    var destroyed = (List<GraphicsResource>)ex.Data["DestroyedObjects"];
    foreach (var r in destroyed) r.Dispose();
    RecreateDeviceAndResources();
}

try { resumeManager.OnRecreate(); } catch (InvalidOperationException ex) when (ex.Data.Contains("DestroyedObjects")) { /* inspect ex.Data["DestroyedObjects"] and rebuild device */ }

When it happens

Trigger: Calling OnRecreate (via OnRender) after a device lost/reset event when at least one registered graphics resource fails to recreate, leaving destroyed objects behind.

Common situations: GPU device removal/reset on mobile or after driver crash, resuming an app after system suspend, or window/backbuffer recreation where a resource's recreation logic fails (e.g. format no longer supported).

Understand the failure class
