What is failing
The NodeType BinaryClickerV2/BinaryToggle cannot build its assembly, so the node type is dead — no BinaryToggle instance can be created or rendered. The single blocking Roslyn error is in its layout-area source: a call to host.GetData<BinaryToggleData>() on a LayoutAreaHost, a method that does not exist on that type. The only GetData<T> in scope is the WorkspaceOperations.GetData<T>(EntityStore) extension, which requires an EntityStore receiver — hence the CS1929.
Probable cause
Author error in the node's own source — high confidence. The read was written against an assumed API:
- Everything else in the diagnostic set is warnings (duplicate
using directives the compile harness prepends, missing XML comments); the GetData call is the only error.
- Layout Areas documents the actual surface: view functions read through
host.Workspace.GetStream<MeshNode>(), and node content goes through GetMeshNodeStream(path) + ContentAs<T> (CRUD Operations).
- The working V1 sibling
BinaryClicker/BinaryToggle/Source/BinaryToggleLayoutAreas uses exactly that pattern and compiles fine.
Impact
Contained and low-severity: a broken node type in a sandbox/demo space ("Binary Clicker V2"); no other spaces or platform components are affected, and the compilation pipeline behaved correctly — it caught the error and reported it with full diagnostics. The defect is persistent, though: the sources have carried it since they were authored in early July, so every pod that attempts this compile will fail the same way until the source is fixed.
Where to look / fix
BinaryClickerV2/BinaryToggle/Source/BinaryToggleLayout — the var data = host.GetData<BinaryToggleData>(); line. Replace with the documented workspace read, mirroring the V1 layout: host.Workspace.GetStream<MeshNode>() filtered to the hub's path, or workspace.GetMeshNodeStream(path).Select(n => n.ContentAs<BinaryToggleData>(...)).
- While there: the button action is
async (_, __) => { await host.UpdateAsync(...); } — the layout docs require synchronous click handlers (return Task.CompletedTask); async handlers can deadlock the layout pump under load.
- Stale near-duplicates of the same broken code sit at
BinaryClickerV2/Source/BinaryToggleData and BinaryClickerV2/Source/BinaryToggleLayout (they are not part of this compile). Fix or delete them so the broken pattern isn't copied back.
- After fixing, recycle the
BinaryClickerV2/BinaryToggle NodeType hub so a fresh compile runs, and confirm it builds.
Checked for existing incidents/issues covering this component and symptom — none found.
