Upshot is officially dead.

"Earlier this year the Beta version of Visual Studio 2012 included a template that was designed for building “single page applications” using Upshot.js and a special Web API-based DataController that provided support for insert, update, and delete operations using the unit of work pattern with transaction support. We are not currently continuing work on that template or Upshot.js. We want to first focus on improving the development experience with existing popular JavaScript libraries and in future versions we will revisit this decision and see if additional libraries are needed to round out the SPA experience."

Give a shot to JayData at <a href="http://jaydata.org" rel="nofollow">http://jaydata.org</a>, it has <a href="http://wikipedia.org/wiki/JSLQ" rel="nofollow">JavaScript Language Query</a> and JavaScript CRUD capabilities with change tracking, batches and a lot more. What it offers over BreezeJS is its provider agnostic architecture and a number of providers that you can use out of the box: OData, webSQL, IndexedDB, localStore, Facebook and YQL.

JayData plays nicely with NodeJS and let you consume OData from a JavaScript based middletier.

Also you can use JayData not only to consume but also to provide OData if you are using it on the server side with NodeJS and mongoDB.

The ASP.NET team haven't finished the official release of ASP.NET SPA in time to ship with the final ASP.NET MVC 4 release but they are still working on it.

You can find the source code for ASP.NET SPA and follow the development effort on the ASP.NET CodePlex site:

<ul>
<li><a href="http://aspnetwebstack.codeplex.com/SourceControl/list/changesets" rel="nofollow">ASP.NET SPA Source Code</a> (to look at the upshot stuff click Browse and expand <code>src/SPA/upshot</code></li>
<li><a href="http://aspnetwebstack.codeplex.com/discussions/topics/5321/asp-net-single-page-application" rel="nofollow">ASP.NET SPA Discussions</a></li>
</ul>

The general lack of documentation is caused by the fact that there haven't be an official release yet.

blocks|key|4338929|text|对于我的公司来说-我们使用了完全相同的组合(Knockout+%2B+Upshot)，在经历了大量的痛苦之后，我们决定摆脱Upshot，并用JQuery的ajax调用来代替它。更透明，更无Much。然而，代码也要多得多。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4338930|早在2月份，Upshot的作者承诺他们将在一周左右的时间内提供文档，从那时起，我就再也没有听到过他们的消息。如果你需要我的意见，我认为这个项目已经被埋没或无限期推迟了。|4338931|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Speaking for my company - we used exactly the same combination (Knockout + Upshot) and after sweating a lot of blood, we decided to get rid of Upshot and replace it with JQuery's ajax calls. Much more transparent and much more bugfree. However, much more code, too.

Back in February the authors of Upshot promised they would put documentation on in a week or so and since then I've heard nothing of them. If you want my opinion, I think this project has already been buried or indefinitely postponed.

blocks|key|2361798|text|根据关于SPA的讨论(参见http://aspnetwebstack.codeplex.com/discussions/topics/5321/asp-net-single-page-application)所说的，整个SPA策略将会改变，所以我认为SPA的最终版本或任何将取代它的东西将与实际的bits...so有很大的不同我不知道这是不是一个好的举动继续使用实际的version...that在我打赌的知识与MVC4RTM不兼容。我是Mvc+Controls+Toolkit的作者，我们在那里实现了一些js函数来帮助查询OData，并更新客户端的实体。它们处理验证错误(客户端和服务器端)，返回在服务器上创建的客户端主体密钥，执行更改跟踪(将刚刚更改的实体发送到服务器)，并允许撤消在客户端所做的更改。它们还处理一对多的关系。此外，不仅使用WebApi控制器处理更新，而且还使用普通控制器处理更新。看一下第一个教程：http://dotnet-programming.com/post/2012/04/03/Mvc-Controls-Toolkit-Support-to-Mvc4-WebApi.aspx，然后参考链接的其他教程。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2361799|entityMap|0|LINK|mutability|MUTABLE|url|http://aspnetwebstack.codeplex.com/discussions/topics/5321/asp-net-single-page-application|1|http://mvccontrolstoolkit.codeplex.com/|2|http://dotnet-programming.com/post/2012/04/03/Mvc-Controls-Toolkit-Support-to-Mvc4-WebApi.aspx^0|D|2I|0|63|K|1|BE|2M|2|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]|$A|T|B|U|1|V]|$A|W|B|X|1|Y]]|C|$]]|$1|D|3|-4|5|6|7|Z|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]|N|$5|G|H|I|C|$J|O]]]]

Accodding to what is said on the discussions(see <a href="http://aspnetwebstack.codeplex.com/discussions/topics/5321/asp-net-single-page-application" rel="nofollow">http://aspnetwebstack.codeplex.com/discussions/topics/5321/asp-net-single-page-application</a>) on SPA, the whole SPA strategy would change, so I think the final version o SPA or whatever will replace it will be quite different from the actual bits...so I don't know if it is a good move continuing using the actual version...that at my bets knowledge is not compatible with Mvc 4 RTM.
I am the author of the <a href="http://mvccontrolstoolkit.codeplex.com/" rel="nofollow">Mvc Controls Toolkit</a> there we implemented some js functions to help querying OData, and to update entitiess that are on the client side. They handle validation errors(both client side and server side), return to client principal keys created on the server, do changes tracking (to send to the server just changed entities) and allows undoing changes done on the client side. They handle also one to many relations. Moreover, updates are handled not only with WebApi controllers but also with normal controllers. 
Give a look to this first tutorial: <a href="http://dotnet-programming.com/post/2012/04/03/Mvc-Controls-Toolkit-Support-to-Mvc4-WebApi.aspx" rel="nofollow">http://dotnet-programming.com/post/2012/04/03/Mvc-Controls-Toolkit-Support-to-Mvc4-WebApi.aspx</a>
and then refer to the other tutorilas linked.

I am thinking of using upshot.js along with Knockout in one of my very important projects. I do not see any documentation or any activity around upshot. Before I commit to this decision, is this project still active? 

If the entire asp.net stack is now open and one can see what is getting committed to repository, why this small library is still not on codeplex or github for community to see? 

I hope this is still on radar of asp.net team.

我正在考虑在我的一个非常重要的项目中使用upshot.js和Knockout。我没有看到任何文档或任何活动的结果。在我做出这个决定之前，这个项目还在运行吗？如果整个asp.net堆栈现在都是开放的，人们可以看到什么正在提交到存储库，为什么这个小库仍然不在codeplex或github上，供社区查看？我希望这仍然在asp.net团队的雷达上。
