+## Testing File Picker Functionality
+
+We've added comprehensive testing for the `FileOpenPicker` functionality, which is now available for WebAssembly (WASM) targets. This implementation demonstrates how to use the Uno Platform's file picker to select files in a cross-platform application.
+
+### Key Features
+
+- **Cross-Platform Support**: Seamlessly works across all Uno Platform targets with a consistent API
+- **File Type Filtering**: Easily specify which file types users can select
+- **Asynchronous Operation**: Non-blocking file selection with proper async/await pattern
+- **Error Handling**: Comprehensive error handling for all file operations
+
+### Example Usage
+
+```csharp
+var picker = new FileOpenPicker
+{
+    ViewMode = PickerViewMode.Thumbnail,
+    SuggestedStartLocation = PickerLocationId.DocumentsLibrary
+};
+
+// Add file type filters
+picker.FileTypeFilter.Add(".txt");
+picker.FileTypeFilter.Add(".jpg");
+picker.FileTypeFilter.Add(".png");
+picker.FileTypeFilter.Add("*");
+
+// Open the file picker
+var file = await picker.PickSingleFileAsync();
+
+if (file != null)
+{
+    // File was selected
+    // Access file properties or read content
+}
+```
+
+### Running Tests
+
+To run the FileOpenPicker tests:
+
+1. Build the solution
+2. Use the test explorer in your IDE
+3. Look for `FileOpenPicker_Tests` in the test list
+
+The tests verify both successful file selection and cancellation scenarios, ensuring robust file handling in your application.
