注意：这个问题在最初发布后几天完全被重写。
我有一个在VS 2012开发的ASP.NET MVC应用程序，部署到Azure。原始项目是从ASP.NET MVC 4项目模板创建的。
NuGet最近开始显示来自微软的大量更新的软件包。 Microsoft HTTP Client Libraries v2.1.10中的其中一个更新会在安装时导致严重的问题。
>它安装MicrosoftBcl.Build，这与我的Azure项目不兼容(有关问题及其解决方案，请参阅this SO question)。
>它导致一大堆“不兼容的DLL”问题(见下文)。
这引发了几个灼热的问题：
>我的MVC应用程序只是一个网站。它只是运行在一个网络浏览器。我需要这个包吗(例如，是否使用模板代码，如果我删除包，它会破坏，可能会巧妙)？
>根据项目网站(http://blogs.msdn.com/b/bclteam/p/httpclient.aspx)，该产品有几个较新的(虽然是beta版本)。我假设我会看到他们，如果我告诉NuGet向我显示未发布的版本。这些版本是否解决了上述问题？
在安装更新的NuGet软件包之后，在构建解决方案时，会发出以下警告：

解决方法
您可以在web.config文件中使用
binding redirects来解决问题。
例如，对于行：
Consider app.config remapping of assembly "DotNetopenAuth.AspNet,PublicKeyToken=2780ccd10d57b246" from Version "4.0.0.0" [] to Version "4.3.0.0"
<configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="DotNetopenAuth.AspNet" publicKeyToken="2780ccd10d57b246" culture="neutral" /> <bindingRedirect oldVersion="1.0.0.0-4.3.0.0" newVersion="4.3.0.0"/> </dependentAssembly> </assemblyBinding> </runtime> </configuration>
等等…对于创建异常的每个dll，都会添加附加的dependencyAssembly节点。
