FreshMvvm 1.0 Preview Release

Since the first release of FreshMvvm it’s been a wild ride, the up take of FreshMvvm has been very impressive it’s really good to see others having success using FreshMvvm. While I’ve been using and loving FreshMvvm for a long long time, even since before it was called FreshMvvm, it’s great to see others also enjoying the Framework.

Since this release has a few large features and breaking changes I’ve decided bump the version up to 1.0 preview. Please see below of a description of the features.

Multiple Navigation Services

It’s always been possible to do any type of navigation in FreshMvvm, with custom or advanced scenarios were done by implementing a custom navigation service. Even with this ability people found it a little hard to do advanced navigation scenarios in FreshMvvm. After I reviewed all the support questions that came in for FreshMvvm I found that the basic issue people had was they wanted to be able to use our built in navigation containers multiple times, two primary examples are 1) within a master detail having a navigation stack in a master and another in the detail 2) The ability to push modally with a new navigation container. In order to support both these scenarios I concluded that the FreshMvvm required the ability to have named NavigationServices so that we could support multiple NavigationService’s.

Using multiple navigation containers

Below we’re running two navigation stacks, in a single MasterDetail.

var masterDetailsMultiple = new MasterDetailPage (); //generic master detail page

//we setup the first navigation container with ContactList
var contactListPage = FreshPageModelResolver.ResolvePageModel<ContactListPageModel> ();
contactListPage.Title = "Contact List";
//we setup the first navigation container with name MasterPageArea
var masterPageArea = new FreshNavigationContainer (contactListPage, "MasterPageArea");
masterPageArea.Title = "Menu";

masterDetailsMultiple.Master = masterPageArea; //set the first navigation container to the Master

//we setup the second navigation container with the QuoteList 
var quoteListPage = FreshPageModelResolver.ResolvePageModel<QuoteListPageModel> ();
quoteListPage.Title = "Quote List";
//we setup the second navigation container with name DetailPageArea
var detailPageArea = new FreshNavigationContainer (quoteListPage, "DetailPageArea");

masterDetailsMultiple.Detail = detailPageArea; //set the second navigation container to the Detail

MainPage = masterDetailsMultiple;

PushModally with new navigation stack

//push a basic page Modally
var page = FreshPageModelResolver.ResolvePageModel<MainMenuPageModel> ();
var basicNavContainer = new FreshNavigationContainer (page, "secondNavPage");
await CoreMethods.PushNewNavigationServiceModal(basicNavContainer, new FreshBasePageModel[] { page.GetModel() }); 

//push a tabbed page Modally
var tabbedNavigation = new FreshTabbedNavigationContainer ("secondNavPage");
tabbedNavigation.AddTab<ContactListPageModel> ("Contacts", "contacts.png", null);
tabbedNavigation.AddTab<QuoteListPageModel> ("Quotes", "document.png", null);
await CoreMethods.PushNewNavigationServiceModal(tabbedNavigation);

//push a master detail page Modally
var masterDetailNav = new FreshMasterDetailNavigationContainer ("secondNavPage");
masterDetailNav.Init ("Menu", "Menu.png");
masterDetailNav.AddPage<ContactListPageModel> ("Contacts", null);
masterDetailNav.AddPage<QuoteListPageModel> ("Quotes", null);
await CoreMethods.PushNewNavigationServiceModal(masterDetailNav);

Custom IOC Container

The second major request for FreshMvvm 1.0 was to allow custom IOC containers. In the case that your application already has a container that you want to leverage.

Using a custom IOC container is very simple in that you only need to implement a single interface.

public interface IFreshIOC
    object Resolve(Type resolveType);
    void Register<RegisterType>(RegisterType instance) where RegisterType : class;
    void Register<RegisterType>(RegisterType instance, string name) where RegisterType : class;
    ResolveType Resolve<ResolveType>() where ResolveType : class;
    ResolveType Resolve<ResolveType>(string name) where ResolveType : class;
    void Register<RegisterType, RegisterImplementation> ()
        where RegisterType : class
        where RegisterImplementation : class, RegisterType;

And then set the IOC container in the System.


Breaking Changes

Please remember whenever you register a IFreshNavigationService it now has to have a name.

FreshIOC.Container.Register<IFreshNavigationService> (this, Constants.DefaultNavigationServiceName);

Please find this pre-release in nuget. –

FYI – This nuget is a pre-release nuget and you’ll need to have the ‘pre-release’ option selected on nuget.
