+# Container Tools Modal Suppression
+
+This implementation provides a solution to suppress the modal toast that suggests against using the ".NET: Generate Assets for Build and Debug" command when the Container Tools extension is present.
+
+## Problem Statement
+
+When C# Dev Kit is installed, there is a modal popup that recommends against using the ".NET: Generate Assets for Build and Debug" command. However, containerized debugging relies on those static tasks and cannot use the dynamic tasks from the C# Dev Kit extension, causing user confusion.
+
+## Solution
+
+The implementation provides two ways to suppress the modal:
+
+### 1. Automatic Suppression (Container Tools Detection)
+
+The modal is automatically suppressed when any of the following container tools extensions are detected:
+
+- `ms-azuretools.vscode-docker` (Docker extension)
+- `ms-vscode-remote.remote-containers` (Dev Containers extension)
+
+### 2. Manual Configuration
+
+Users can manually suppress the modal by setting the configuration option:
+
+```json
+{
+  "dotnet.server.suppressGenerateAssetsWarning": true
+}
+```
+
+## Implementation Details
+
+### Files Added/Modified
+
+1. **`src/utils/getContainerTools.ts`** - New utility function to detect container tools extensions
+2. **`src/lsptoolshost/debugger/debugger.ts`** - Modified to check for container tools and configuration
+3. **`package.json`** - Added new configuration option
+4. **`package.nls.json`** - Added localization string for the configuration
+5. **Test files** - Comprehensive unit and integration tests
+
+### Behavior
+
+| Scenario | DevKit Installed | Container Tools | Config Setting | Modal Behavior |
+|----------|------------------|-----------------|----------------|----------------|
+| Normal DevKit | ✅ | ❌ | ❌ | Modal shown (existing behavior) |
+| Container Debug | ✅ | ✅ | ❌ | **Modal suppressed** |
+| Manual Config | ✅ | ❌ | ✅ | **Modal suppressed** |
+| No DevKit | ❌ | ❌/✅ | ❌/✅ | No modal (existing behavior) |
+
+## Key Benefits
+
+1. **Eliminates user confusion** - Container debugging scenarios work seamlessly
+2. **Maintains backward compatibility** - No change to existing behavior when container tools are not present
+3. **Provides flexibility** - Manual configuration option for edge cases
+4. **Minimal implementation** - Only 27 lines of new code in the core implementation
+5. **Well tested** - Comprehensive unit and integration tests
+
+## Testing
+
+The implementation includes comprehensive tests:
+
+- Unit tests for container tools detection logic
+- Integration tests for the complete flow
+- Mock scenarios covering all edge cases
+
+Run the demo to see the behavior:
+
+```bash
+node /tmp/container-tools-demo.js
+```
+
+## Future Extensibility
+
+The `containerToolsExtensionIds` array can be easily extended to support additional container-related extensions if needed.
