升级MVC4到MVC5时出现问题

本文关键字:问题 MVC5 MVC4 升级 | 更新日期: 2023-09-27 18:02:54

我正试图将MVC4升级到MVC5,但奇怪的事情发生了。我使用了一个非常好的指南,我发现和一切编译OK,但是当我试图显示网站我得到这个错误:

无法加载文件或程序集"System.Web"。"帮手"或其中一个依赖关系。定位的程序集的清单定义不会匹配程序集引用。(Exception from HRESULT: 0x80131040)

奇怪的是,当我看到对System.Web. net的程序集引用时。Mvc,包含。剃须刀,包含。网页等,他们都仍然在属于MVC4的版本号!我尝试重新安装相应的nuget包,它给了我您希望得到的输出:

PM> Update-Package -reinstall -Id Microsoft.AspNet.Razor
Removing 'Microsoft.AspNet.Razor 3.2.3' from LabManager.Web.

You are downloading Microsoft.AspNet.Razor from Microsoft, the license agreement to which is available at http://www.microsoft.com/web/webpi/eula/net_library_eula_ENU.htm. Check the package for additional dependencies, which may come with their own license agreement(s). Your use of the package and dependencies constitutes your acceptance of their license agreements. If you do not accept the license agreement(s), then delete the relevant components from your device.

Adding 'Microsoft.AspNet.Razor 3.2.3' to LabManager.Web.
Successfully added 'Microsoft.AspNet.Razor 3.2.3' to LabManager.Web.

表示已经安装了正确的版本。然而,System.Web.Razor的参考资料仍然显示它的版本是2.0.0.0。此外,我正在编译。net版本4.5.1,但运行时版本的System.Web.Razor仍然显示4.0.3.0319。这同样适用于所有MVC相关的程序集(除了System.Web.Mvc的版本号是4.0.0.0而不是5.x.x.x)。

帮助!有人知道这是怎么回事吗?

升级MVC4到MVC5时出现问题

你的绑定重定向有问题,它们应该如下:

    <dependentAssembly>
      <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
    </dependentAssembly>
    <dependentAssembly>
      <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
    </dependentAssembly>
    <dependentAssembly>
      <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
    </dependentAssembly>

在当前设置中,HelpersWebPages指向版本2,Mvc指向版本4。

您还需要检查所有视图web。配置,以确保他们也使用正确的版本。

我使用这个指南来更新我的应用程序:

如何升级ASP。asp.net MVC 4和Web API项目。. NET MVC 5和Web API 2

事实证明,引用的程序集不是由mvc5 nuget包安装的程序集,而是由一堆旧的程序集在一个名为'_bin_deployableAssemblies'的文件夹中。我只是删除了那个文件夹,然后visual studio自己找到了新的文件夹。MVC相关程序集的版本号现在显示正确,应用程序运行得很好。
