你可以通过将项目升级到. net Framework 4.7.2来解决这个问题。这个问题由微软的Alex giondea回答。请给他投票，因为他真的值得!

This is documented as a known issue in .NET Framework 4.7.1. As a workaround you can add these targets to your project. They will remove the DesignFacadesToFilter from the list of references passed to SGEN (and add them back once SGEN is done) <Target Name="RemoveDesignTimeFacadesBeforeSGen" BeforeTargets="GenerateSerializationAssemblies"> <ItemGroup> <DesignFacadesToFilter Include="System.IO.Compression.ZipFile" /> <_FilterOutFromReferencePath Include="@(_DesignTimeFacadeAssemblies_Names->'%(OriginalIdentity)')" Condition="'@(DesignFacadesToFilter)' == '@(_DesignTimeFacadeAssemblies_Names)' and '%(Identity)' != ''" /> <ReferencePath Remove="@(_FilterOutFromReferencePath)" /> </ItemGroup> <Message Importance="normal" Text="Removing DesignTimeFacades from ReferencePath before running SGen." /> </Target> <Target Name="ReAddDesignTimeFacadesBeforeSGen" AfterTargets="GenerateSerializationAssemblies"> <ItemGroup> <ReferencePath Include="@(_FilterOutFromReferencePath)" /> </ItemGroup> <Message Importance="normal" Text="Adding back DesignTimeFacades from ReferencePath now that SGen has ran." /> </Target> Another option (machine wide) is to add the following binding redirect to sgen.exe.config: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="System.IO.Compression.ZipFile" publicKeyToken="b77a5c561934e089" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-4.2.0.0" newVersion="4.0.0.0" /> </dependentAssembly> </assemblyBinding> </runtime> This will only work on machines with .NET Framework 4.7.1. installed. Once .NET Framework 4.7.2 is installed on that machine, this workaround should be removed.

更改我的网页中的绑定信息。config(或app.config) -虽然在我看来是一个“黑客”，允许你在NuGet包更新后继续你的项目，并给你System.Net.Http错误。

设置oldVersion="0.0.0.0-4.1.1.0"和newVersion="4.0.0.0"如下所示

<dependentAssembly>
    <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.1.1.0" newVersion="4.0.0.0" />
</dependentAssembly>

请遵循以下步骤:

Update Visual Studio to to latest version (it matters) Remove all binding redirects from web.config Add this to the .csproj file: <PropertyGroup> <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects> <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType> </PropertyGroup> Build the project In the bin folder there should be a (WebAppName).dll.config file It should have redirects in it, copy these to the web.config Remove the above snipped from the .csproj file

它应该会起作用。

在我的一个项目中，有一个带有System.Net.Http更高版本的nuget包。在我的启动项目中引用System.Net.Http v 4.0.0，我刚刚在我的启动项目中安装了System.Net.Http nuget包，问题解决了
