+# XAML Errors and Warnings
+
+When authoring XAML, Visual Studio analyzes the code as you type. A squiggle appears on a line of code when an error is detected. Hovering over the squiggle gives you more information about the error or warning. For some errors and warnings, a Quick Action lightbulb is displayed, and using the **Ctrl**+**.** keyboard shortcut displays the options to fix the issue.
+
+## Error types
+
+Behind the scenes, multiple tools analyze the XAML in parallel. XAML errors are categorized into one of the following three types, based on the tool that detected the error:
+
+|**Error detected by**|**Error code format**|  
+|--------------------------------|-----------------|  
+|XAML Language Service (XAML editor)|XLSxxxx|  
+|XAML Designer|XDGxxxx|  
+|XAML Edit and Continue|XECxxxx|  
+
+> [!Note]
+> Not all errors/warnings have a corresponding code. Such errors are usually XAML Designer errors.
+
+
+## Suppress XAML Designer errors
+
+Open the **Options** dialog by selecting **Tools > Options**, and then select **Text Editor > XAML > Miscellaneous**.
+
+Uncheck the **Show errors detected by the XAML designer** check box.
