SimpleIoc crib sheet:

1) You register all your interfaces and objects in the ViewModelLocator

<pre><code>class ViewModelLocator 
{ 
 static ViewModelLocator() 
 { 
 ServiceLocator.SetLocatorProvider(() =&gt; SimpleIoc.Default); 
 if (ViewModelBase.IsInDesignModeStatic) 
 { 
 SimpleIoc.Default.Register&lt;IDataService, Design.DesignDataService&gt;(); 
 } 
 else 
 { 
 SimpleIoc.Default.Register&lt;IDataService, DataService&gt;(); 
 } 
 SimpleIoc.Default.Register&lt;MainViewModel&gt;(); 
 SimpleIoc.Default.Register&lt;SecondViewModel&gt;(); 
 } 


 public MainViewModel Main 
 { 
 get 
 { 
 return ServiceLocator.Current.GetInstance&lt;MainViewModel&gt;(); 
 } 
 }
} 
</code></pre>

2) Every object is a singleton by default. To resolve an object so that it's not a singleton you need to pass a unique value to the GetInstance call:

<pre><code>SimpleIoc.Default.GetInstance&lt;MainViewModel&gt;(Guid.NewGuid().ToString());
</code></pre>

3) To register a class against an interface:

<pre><code>SimpleIoc.Default.Register&lt;IDataService, Design.DesignDataService&gt;(); 
</code></pre>

4) To register a concrete object against an interface:

<pre><code>SimpleIoc.Default.Register&lt;IDataService&gt;(myObject); 
</code></pre>

5) To register a concrete type:

<pre><code>SimpleIoc.Default.Register&lt;MainViewModel&gt;(); 
</code></pre>

6) To resolve an object from an interface:

<pre><code>SimpleIoc.Default.GetInstance&lt;IDataService&gt;();
</code></pre>

7) To resolve an object directly (does buildup and dependency resolution):

<pre><code>SimpleIoc.Default.GetInstance&lt;MainViewModel&gt;();
</code></pre>

8) MVVM makes doing design-time data really easy:

<pre><code>if (ViewModelBase.IsInDesignModeStatic) 
{ 
 SimpleIoc.Default.Register&lt;IDataService, Design.DesignDataService&gt;(); 
} 
else 
{ 
 SimpleIoc.Default.Register&lt;IDataService, DataService&gt;(); 
} 
</code></pre>

If you're in design-time mode it will automatically register your design-time services, making it really easy to have data in your viewmodels and views when working in the VS designer.

Hope this helps.

I'm revamping my software which has messy <code>Messenger.Default(...)</code> bits.

Is there any cheat sheet to know MVVMLight SimpleIoc usage (not general IoC description)?

how to use MVVMLight SimpleIoc?

我正在修改我的软件，它有一些凌乱的Messenger.Default(...)位。有没有什么小抄可以知道MVVMLight SimpleIoc的用法(不是一般的IoC描述)？
