This project was created as a wrapper for the ClickOnce in .NET 5, because in this version ApplicationDeployment was not implemented.
The main project is PureManApplicationDeployment and you can embed it into your application. Unfortunately, I have not found a way to receive UpdateUrl so this property must be hardcoded. The WpfSettings project is just an example of how you can work with the PureManApplicationDeployment library and shows main functionality.
