Assembly Information dialog box

The Assembly Information dialog box is used to specify the values of the .NET Framework global assembly attributes, which are stored in the AssemblyInfo file created automatically with your project. In Solution Explorer, the AssemblyInfo file is located in the My Project node for Visual Basic projects (click Show All files to view it). For C# projects, it's located under Properties. For more information, see Attributes (C#).

To access this dialog box, select a project node in Solution Explorer, and then, on the Project menu, select Properties. On the Application page, select the Assembly Information button.


The information in this topic only applies to .NET Framework projects, not .NET Core or .NET 5 and later projects. For those projects, edit the AssemblyInfo file directly.
