Cannot find StaticResource @{position}

Error message

Cannot find StaticResource @{position}

What it means

Thrown by StaticResourceIdHandler.Translate for the same reason as [11] but for a standalone StaticResourceId record: XamlResourceKey.FindKeyInAncestors returns null because no ancestor resource key provides static resources for record.StaticResourceId.

Solutions

  1. Use the position in the message to find the dangling record.
  2. Re-extract from a clean assembly.
  3. Skip the record and continue.
Defensive patterns

Strategy: try-catch

Try / catch

try {
    handler.Translate(ctx, node, parent);
} catch (Exception ex) when (ex.Message.StartsWith("Cannot find StaticResource")) {
    // unresolved StaticResourceId; continue with remaining nodes
}

Prevention

When it happens

Trigger: A StaticResourceId record with no enclosing resource key (StaticResourceStart block) among its ancestors that owns the referenced id.

Common situations: Malformed/truncated BAML resource references; missing StaticResourceStart.
