我很欣赏 你的 意见，
For the survey
conducted, we see that more

applications development, is
followed by the MVVM, what
are the advantages of
this in relation to
MVC, since
we aremore
familiar with MVC (Model-View-Controller)?
I appreciate your opinion,

推荐答案
MVVM优于MVC的优势 -
Advantages of MVVM over MVC -
1.增加视图的"可混合性"（使用Expression Blend设计视图的能力） - 这样做对有幸拥有设计师和程序员的团队的责任分离......每个人都可以独立于另一个人工作。
1. Increases the "Blendability" of your views (ability to use Expression Blend to design views) – This enables a separation of responsibilities on teams that are lucky enough to have a designer and a programmer... each can work independent of the other.
2."Lookless"视图逻辑 - 视图与在其后面运行的代码无关，使得相同的视图逻辑可以在多个视图中重用，或者可以轻松地重新组合或替换视图。分离"行为"和"样式"之间的关注。
2. "Lookless" view logic – Views are agnostic from the code that runs behind them, enabling the same view logic to be reused across multiple views or have a view easily retooled or replaced. Seperates concerns between "behavior" and "style".
3.没有重复的代码来更新视图 - 在代码隐藏中你会看到很多调用更新视图控件。使用MVVM你可以确保视图只是通过适当的更新设置基础属性和所有查看其副作用。
3. No duplicated code to update views – In code-behind you will see a lot of calls to update view controls. With MVVM you can be assured the view is updated appropriately just by setting the underlying property and all view side-effects thereof.
4。可测试性 - 由于您的逻辑与您的视图完全无关，因此单元测试变得简单。您可以在不涉及其视图的情况下测试ViewModel的行为。这也启用了测试驱动的视图行为开发，使用代码隐藏几乎是不可能的
。
4. Testability – Since your logic is completely agnostic of your view, unit testing is made easy. You can test the behavior of a ViewModel without involving its view. This also enabled test-driven development of view behavior, which is almost impossible using code-behind.
5。 Designer-Developer工作流程 - MVVM有助于将UI和表示逻辑问题从业务层分离出来，通过允许设计周期与开发并行发生，可以轻松简化开发过程。
5. Designer-Developer Workflow – MVVM facilitates a separation of UI and presentation logic concerns from the business layer that makes it easy to streamline the development process by allowing design cycles to happen in parallel with development.
