Provides properties for getting the information about the application, such as the version number, description, loaded assemblies, and so on.

Namespace:  Microsoft.VisualBasic.ApplicationServices
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, Resources = HostProtectionResource.ExternalProcessMgmt)]
public class AssemblyInfo


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: Resources. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

For more detailed information, see the Visual Basic topic My.Application.Info Object.

Some of the properties exposed by the My.Application.Info object return the application's assembly information. To set the information in the application's assembly, you must use the Assembly Information dialog box, accessible from the Application pane of the Project Designer. For more information, see How to: Specify Assembly Information (Visual Basic, C#).

The My.Application.Info object provides functionality similar to the FileVersionInfo class but is scoped to give quick access to the most common properties.

Other properties, such as LoadedAssemblies, provide access to the current state of the application.

This example uses the My.Application.Info.Version property to display the version of the application.

MsgBox("Application version: " & My.Application.Info.Version.ToString)
