# VS_DOTNET_STARTUP_OBJECT

Added in version 3.24.

Sets the startup object property in Visual Studio .NET targets. The property value defines a full qualified class name (including package name), for example: `MyCompany.Package.MyStarterClass`.

If the property is unset, Visual Studio uses the first matching `static void Main(string[])` function signature by default. When more than one `Main()` method is available in the current project, the property becomes mandatory for building the project.

This property only works for Visual Studio Generators; it is ignored on other generators.
