asp.net-web-api - GlobalConfiguration-尝试访问字段'<> 9__CachedAnonymousMethodDelegate2'失败

设置依赖关系解析器时出现此错误。码： GlobalConfiguration.Configuration.DependencyResolver =新的UnityDependencyResolver（container）;错误： 尝试通过方法'System.Web.Http.GlobalConfiguration..cctor（）'访问字段'System.Web.Http.GlobalConfiguration.CS $ 9__CachedAnonymousMethodDelegate2'失败。我在这里想念什么？发布的所有解决方案都涉及安装最新版本的Microsoft.AspNet.WebApi。 安装包Microsoft.AspNet.WebApi -IncludePrerelease但是，我已经拥有所需程序集的所有最新版本，并且仍然出现此错误。<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31BF3856AD364E35" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-5.1.0.0" newVersion="5.1.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Web.Optimization" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="1.1.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="0.0.0.0-5.1.0.0" newVersion="5.1.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="DotNetOpenAuth.AspNet" publicKeyToken="2780ccd10d57b246" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-4.3.0.0" newVersion="4.3.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="DotNetOpenAuth.Core" publicKeyToken="2780ccd10d57b246" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-4.3.0.0" newVersion="4.3.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-5.1.0.0" newVersion="5.1.0.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-5.1.0.0" newVersion="5.1.0.0" /> </dependentAssembly></assemblyBinding> (adsbygoogle = window.adsbygoogle || []).push({}); 最佳答案 已安装软件包，但显然某些引用是从GAC而不是从NuGet软件包文件夹中获取的。这些是手动删除的，我在packages文件夹中添加了引用，并且可以正常工作。（应该有一个NuGet功能来“清理”引用，以便它们从packages文件夹而不是其他位置获取。） (adsbygoogle = window.adsbygoogle || []).push({});
