Font Awesome字体使用

Step1: 下载地址为：/

Step2:复制 f 字体到项目中，并在字典中引用该字体
字典中引用字体

   <FontFamily x:Key="FontAwesome">pack://application:,,,/MafengWo;component/Fonts/#FontAwesome</FontFamily>

如取f110

PropertyChanged.Fody

Nuget安装

安装 PropertyChanged.Fody NuGet 软件包并更新Fody NuGet包:

Install-Package Fody
Install-Package PropertyChanged.Fody

这个Install-Package Fody这是必需的，因为NuGet总是默认为任何依赖项的最古老和最错误的版本。

添加到l

加到l

<Weavers><PropertyChanged/>
</Weavers> 

特别提醒：VS2017 安装2.61 版本

Costura.Fody

方法同 PropertyChanged.Fody

<?xml version="1.0" encoding="utf-8"?>
<Weavers xmlns:xsi="" xsi:noNamespaceSchemaLocation="FodyWeavers.xsd"><Costura /><PropertyChanged/>
</Weavers>

BaseViewModel

 [AddINotifyPropertyChangedInterface]
public class BaseViewModel : INotifyPropertyChanged
{public event PropertyChangedEventHandler PropertyChanged = (sender, e) => { };public void OnPropertyChanged(string name){PropertyChanged(this, new PropertyChangedEventArgs(name));}
}

所有 ViewModel 全部继承自 BaseViewModel

该基类实现了 [AddINotifyPropertyChangedInterface] 接口，这样在编译的时候将PropertyChanged方法植入到public属性的Set方法中，这样就不必为每个Set都写PropertyChanged了

BasePage

public class BasePage<VM> : Pagewhere VM :BaseViewModel,new ()
{#region private Member/// <summary>/// The view Model associated with this page/// </summary>private VM mViewModel;#endregion#region Properties/// <summary>/// The animition the play when the page is first loaded/// </summary>public PageAnimation PageLoadAnimation { get; set; } = PageAnimation.SlideAndFadeInFromRight;/// <summary>/// The animition the play when the page is first unloaded/// </summary>public PageAnimation PageUnLoadAnimation { get; set; } = PageAnimation.SlideAndFadeInFromLeft;/// <summary>/// The time to Animation takes complete/// </summary>public float SlideSeconds { get; set; } = 0.8f;/// <summary>/// The view Model associated with this page/// </summary>public VM ViewModel{get{return mViewModel;}set{//if nothing has changed ,returnif (mViewModel == value)return;//Update the valuemViewModel = value;//Set data contenxt for this pagethis.DataContext = mViewModel;}}#endregion#region Constructorpublic BasePage(){if (PageLoadAnimation != PageAnimation.None)Visibility = Visibility.Collapsed;//Listen out for page loadingLoaded += BasePage_Loaded;//Create a default view modelthis.ViewModel = new VM();}#endregion#region Animation Load / Unload/// <summary>/// Once the page is loaded ,perform any requied animation/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private async void BasePage_Loaded(object sender, System.Windows.RoutedEventArgs e)// use void   {await AmimationIn();}public async Task AmimationIn(){if (PageLoadAnimation == PageAnimation.None)return
