I´m creating an app using the TempHire demo as base.

In TempHire on the ShellViewModel the workspaces are collected and CREATED througout the MEF IOC. how you do build the same idea but not CREATING the WorkSpaces on app Start, but when the Toolbar to the View is pressed?

 

thanks in advanced.

    public class StaffingResourceWorkspace : LazyWorkspace<StaffingResourceManagementViewModel>
    {
        public StaffingResourceWorkspace()
            : base("Resource Management", false, 10)
        {
        }
    }

IWorkspace now has a Content property that returns the actual workspace content, which in case of LazyWorkspace gets lazy instantiated upon first access.

 

    [InterfaceExport(typeof(IWorkspace))]
    public interface IWorkspace : IHaveDisplayName
    {
        bool IsDefault { get; }

        int Sequence { get; }

        IScreen Content { get; }
    }

LazyWorkspace just holds metadata about the workspace itself.

 

In the Shell, the NavigationService is then configured with a custom activator, which activates the content instead of the workspace itself.

 

            _navigationService = new NavigationService<IWorkspace>(this)
                .Configure(config => config.WithActivator(navigation => ActivateItem(navigation.Target.Content)));
