System.IO.FileNotFoundException：无法加载文件或程序集System.Buffers或其依赖项之一。系统找不到指定的文件

Question

我有一个 .NET 4.8 类库，我在其中使用 Azure.Storage.Blobs nuget 将文件上传到 Azure。 与 Azure 的连接已成功建立，但是我在文件上传之前收到错误 -

blockBlobClient.Upload(uploadFileStream);

错误指出-

System.IO.FileNotFoundException: Could not load file or assembly 'System.Buffers, Version=4.0.2.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.

我的 DLL 的名称是 AzureMain，它是从同一 .net 4.8 框架中名为 AzureWrapper 的另一个 DLL 调用的。

我尝试将绑定重定向添加到 app.config as-

<dependentAssembly>
   <assemblyIdentity name="System.Buffers" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
   <bindingRedirect oldVersion="4.0.2.0" newVersion="4.0.3.0" />
</dependentAssembly>

然而这并没有奏效。另外，我检查了nuget System.Buffers，这个nuget没有公开发布版本4.0.2.0

Answer 1

确保绑定重定向位于正在运行的应用程序的应用程序项目的

app.config

或

web.config

中。在您的情况下，这可能是

AzureWrapper

，或者可能是引用

AzureWrapper

的另一个项目。
