VS2012 NuGet更新导致生成时的神秘警告

Question

最近的Visual 2012更新似乎破坏了我的构建中的某些内容。我认为这与上周的nuget更新有关。

NuGet package restore started.
All packages are already installed and there is nothing to restore.
NuGet package restore finished.
1>------ Rebuild All started: Project: Project1, Configuration: Debug Any CPU ------

我如何解决这些警告？我的应用程序出现了一些奇怪的副作用，比如:不一致的模型绑定(与Edm程序集相关？)。

Answer 1

我不知道你为什么认为这很神秘，这很清楚。您已经安装了多个版本的这些包(5.2和5.6) --一些组件引用了5.2和5.6，这导致了警告。这意味着您的别名为5.2到5.6，因此引用5.2的程序集将使用5.6。

不过，这可能不是最好的方法，除非您无法控制这些程序集。您可能应该卸载5.2包，然后将nuget引用更新到5.6版本并重新构建。

Answer 2

如消息所示，您可以通过将程序集版本5.2映射到版本5.6来修复这些警告。您可以通过编辑配置文件的assemblyBinding来做到这一点。在本例中，添加以下XML：

<dependentAssembly>
    <assemblyIdentity name="Microsoft.Data.OData" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.0.0" newVersion="5.6.0.0" />
</dependentAssembly>
<dependentAssembly>
    <assemblyIdentity name="Microsoft.Data.Edm" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.0.0" newVersion="5.6.0.0" />
</dependentAssembly>
<dependentAssembly>
    <assemblyIdentity name="System.Spatial" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="0.0.0.0-5.2.0.0" newVersion="5.6.0.0" />
</dependentAssembly>
