Description 

Sign the assembly 

Use the Microsoft Strong Name utility to sign the assembly (executable, DLL, etc.) produced by the project. Refer to the Microsoft .NET SDK for more information about signing.  

Strong name key file 

Specifies the file with the signature. Click [...] to display a dialog to browse for the file.  

Delay sign only 

Delay signing the assembly produced by the project. You would use this only if there is some post build step you need to perform on the assembly. This is typically not checked, since failing to sign prevents you from running or debugging the assembly.
