It seems like you're referring to the Quick Actions feature in Visual Studio for ASP.NET development. Quick Actions provide shortcuts to common coding tasks, allowing you to quickly refactor, generate code, fix issues, and more, directly from your code editor.
Here's how you can use Quick Actions in Visual Studio for ASP.NET development:
Fixing Errors: If there's a syntax error or warning in your code, Quick Actions can provide suggestions to fix it. For example, if you misspell a method name or forget to include a using directive, Quick Actions will underline the issue and provide options to resolve it.
Refactoring Code: Quick Actions can help you refactor your code to improve readability and maintainability. For example, if you have duplicate code blocks, you can use Quick Actions to extract them into a separate method or variable.
Generating Code: Quick Actions can generate code snippets to speed up development. For example, if you declare a variable but forget to initialize it, Quick Actions can generate the initialization code for you.
Applying Code Fixes: Quick Actions can apply suggested fixes for common code issues, such as adding missing using directives, implementing missing interface members, or converting foreach loops to LINQ expressions.
Navigating to Related Code: Quick Actions can help you navigate to related code elements, such as base classes, derived classes, interface implementations, or method definitions.
To use Quick Actions in Visual Studio, simply hover over the code element you want to modify, and a lightbulb icon will appear. Clicking on the lightbulb icon or pressing Ctrl + . will display a menu of available Quick Actions for that code element. Then, you can select the desired action from the menu or press the corresponding keyboard shortcut.
