C# 无法加载文件或程序集'；Microsoft.SqlServer.Management.RegisteredServers，版本=15.2.0.0，区域性=neutral，PublicKeyToken=89845dcd8080cc91'；

根据我在中的回答，我安装了

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

它在基于.Net Core 2.0的Console应用程序和基于.Net标准2.0的类库上工作：

现在，我在基于.Net Framework 4.7.1的Web应用程序和基于.Net Standard 2.0的类库的主要C#解决方案中使用了它们：

我得到了这个错误：

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)

详情如下：

我尝试了不同的解决方案，比如

---

但它们不起作用

最后，一组解决方案奏效了：

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 Manager控制台运行此命令以添加新绑定：

Get-Project -All | Add-BindingRedirect

3） 正在删除

C:\WINDOWS\Microsoft.NET\Framework\~\ASP.NET临时文件\目录

4） 将

dependentAssembly

添加到web.config：

  <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">
