Question

我将DNN从7.0.0升级到7.1.1。之后，每次我在我的站点中输入DNN的页面站点设置或主机设置时，我都会收到例外。例外是：

Could not load file or assembly 'protobuf-net, Version=2.0.0.447, Culture=neutral, PublicKeyToken=257b51d87d2e4d67' or one of its dependencies. The system cannot find the file specified.

以下是完整的内部异常：

我已经搜索了关于protobuf-net和DNN的所有内容，但我还没有找到任何内容。

任何人都知道这件事吗？

修改

最后，问题解决了。问题是我安装的模块引用了protobuf-net。该模块调用ZeneXa Newsletter Autoresponder。不知何故，此模块与7.0.0以上的DNN版本不兼容。我联系了该模块以获取更多相关信息。

Answer 1

我完全不知道DNN如何使用它，但在最简单的层面上你可以尝试添加对适当版本的protobuf-net的引用（可能from NuGet是最简单的），并且看到如果有效。这可以通过UI或包管理器控制台完成：

PM> Install-Package protobuf-net

如果问题实际上是“融合”，那么绑定重定向可能会有所帮助 - 例如，将所有内容重定向到r668（假设您使用的是protobuf-net r668）：

<dependentAssembly>
  <assemblyIdentity name="protobuf-net" publicKeyToken="257b51d87d2e4d67"
                    culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-2.0.0.668" newVersion="2.0.0.668" />
</dependentAssembly>

站点设置或主机设置页面上的DNN例外“无法加载文件或程序集'protobuf-net”
