版本1.2.4与框架4.0不兼容

Question

我今天正在从头开始重建我的应用程序并使用NuGet将breeze安装到我的应用程序中，并且它在依赖项上失败了。对于接下来的两个版本，我被迫使用framework 4.0而不是4.5。是否有解决依赖性问题的方法？

Answer 1

Breeze应该可以在.NET 4中正常工作。要确认这一点，只需创建一个针对.NET 4的新的ASP.NET MVC4 Web Api项目，并添加其中一个breeze nuget包。要么安装和工作没有问题。

我猜你的项目中有一些旧的nuget包refs。例如，我看到refs为“Microsoft.AspNet.WebApi.WebHost（≥5.0.0-alpha ...”。Breeze本身不依赖于任何“alpha”nuget包。

希望这可以帮助。

另外...确保您的Web.config具有以下重定向：

      <dependentAssembly>
        <assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" culture="neutral" />
       <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
      </dependentAssembly>
