Generate Partial Members
Partial members are defined in different parts of a partial type — one part contains the signature of the member while the other part contains its implementation. C# 13 adds support for partial properties in addition to partial methods, which were available previously.
The Generate partial members command will help you create implementation stubs for not implemented partial members.
Generate implementations of partial members in a partial type
In the editor, place the caret within a partial type at the line where you want to insert implementations of partial members.
Press Alt+Insert or choose from the main menu. Alternatively, you can press Ctrl+Shift+A, start typing the command name in the popup, and then choose it there.
In the Generate popup, select Partial Members.
In the Generate dialog that appears, select partial members to create implementation stubs for.
Click OK to complete the wizard.
