Question

我使用VS2013创建了一个Asp.Net MVC并使用nuget添加HotTowel（2013年9月11日的V2.0.1）。我创建了几个ViewModel，Models。但是，我收到了以下错误。

听起来“Breeze Server（已废弃）”和EF6存在问题。但是，当我尝试安装非过时的Breeze for EF6时失败了。

安装EFV版本的微风错误。

您使用的是Durandal HotTowel吗？如果是这样，我们（约翰和我）还没有更新，以应对与11月VS 2013版本相关的变化。我们落后了。还没有解决方法。请继续关注。

EF6和Breeze 1.4.6（已废弃）不适用于hottowel项目
