无法加载文件或程序集“Microsoft.SqlServer.Management.RegisteredServers，版本=15.2.0.0，文化=中性，PublicKeyToken=89845dcd8080cc91”

Question

根据我在Unable to create RegisteredServer in Microsoft.SqlServer.Management.RegisteredServers 中的回答，我安装了

Microsoft.SqlServer.SqlManagementObjects
Microsoft.SqlServer.Smo
System.Security.Cryptography.ProtectedData

它适用于基于.Net Core 2.0 的Consol Application 和基于.Net Standard 2.0 的ClassLibrary：

现在我在我的主要 C# 解决方案中使用它们，其中 Web 应用程序基于.Net Framework 4.7.1 和 Class 库基于.Net Standard 2.0：

我收到了这个错误：

Could not load file or assembly 'Microsoft.SqlServer.Management.RegisteredServers, Version=15.2.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

这是细节：

我尝试了不同的解决方案，例如定位程序集的清单定义与程序集引用不匹配，但它们不起作用

Answer 1

最后，解决方案的组合起作用：

1）删除obj和bin文件夹

2) 更新 web.config 文件中的引用，然后从 NuGet Package 管理器控制台运行此命令以添加新绑定：

Get-Project -All | Add-BindingRedirect

3）删除C:\WINDOWS\Microsoft.NET\Framework\~\Temporary ASP.NET Files\ directory

4) 在 web.config 中添加dependentAssembly ：

  <dependentAssembly>
    <assemblyIdentity name="Microsoft.SqlServer.Management.RegisteredServers" publicKeyToken="89845dcd8080cc91" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-15.100.0.0" newVersion="15.100.0.0" />
  </dependentAssembly>

它应该与 project.cspj 相同：

 <Reference Include="Microsoft.SqlServer.Management.RegisteredServers, Version=15.100.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91, processorArchitecture=MSIL">
  <HintPath>..\packages\Microsoft.SqlServer.SqlManagementObjects.150.18208.0\lib\net45\Microsoft.SqlServer.Management.RegisteredServers.dll</HintPath>
