While I already posted a similar question (Breeze compatible SPA building) and likely started something good going between IdeaBlade and Telerik as a consequence, I believe that Breeze deserves a lot wider recognition because of its unique approach to access Entity Framework on the server side. So, it seems pretty obvious to me that even notoriously complete JS frameworks like Sencha or Wakanda need to ensure to work with Breeze.
The current issues between KendoUI and Breeze are very clearly described in the post by Remco Blok at http://www.kendoui.com/blogs/teamblog/posts/13-02-21/breeze_js_and_the_kendo_ui_datasource.aspx. Stated succinctly the integration with Breeze should be made at the level of entities - not JSON data, which is the way almost everyone handles the transactions between a JS client and SQL server.
Wakanda is a great example of a very rich development environment with elaborate GUI Builder, Debugger etc that unfortunately cannot be used with "legacy data" on the server side.
As far as I know, Breeze works just fine with Angular, but Angular needs AngularUI (http://angular-ui.github.io/) which in turn is not as complete as I would like it to be and has some JQuery dependencies that may cause collisions. Pretty soon, Breeze will work with KendoUI (AFAIK) - does anyone know about some other collection of JavaScript frameworks that all together would offer the level of ease that Visual Studio provides for Windows desktop applications creation? (after all, JavaScript applications are desktop application with the distribution problem solved in a very elegant fashion).
