This property is used when this component is scanned at build time (based on the .NET Scan at Build property) or by the Static Scanning wizard. The scanner uses this property—along with the component destination—to determine the value of the File Application property for the assembly.

For optimal advertising and repair, set this property to the .NET executable that uses the assembly in this component.

The key file of the component is displayed in this field if the .NET Scan at Build property is set to Dependencies and Properties or Properties. You can select any other key or portable executable file in the project.

This value is ignored if the file selected is not an assembly (.NET) file.
