In Visual Basic projects, Visual C# projects, and XML files, you can use the Code Snippets Manager to add folders to the folder list that the Code Snippet Picker scans for XML .snippet files. Having these building blocks of code at your disposal can facilitate project development.
Whenever you store a new snippet in a folder accessed by the Code Snippets Manager, you are responsible for ensuring that its code is constructed as securely as the rest of your application. Because using code snippets saves development time, snippets can be reused frequently as you construct applications. You should therefore make sure that model code saved in snippets is designed to address security issues. Development teams should establish procedures to review code snippets for compliance with general security standards. For further information on code security, see Security in Visual Studio and Secure Coding Guidelines.
