无法加载文件或程序集Microsoft.Owin.Security.OAuth,Version = 2.0.0.0

Question

我有一个带有OAuth身份验证的MVC项目,每次我尝试调试项目时,在配置IAppBuilder时都会遇到FileLoadException.我已经使用PMC安装了Microsoft.Owin.Security.Oauth 3.0.1版,但我想某处仍然是对旧版本软件包的引用,因为......

这是例外:

这是抛出的地方:

public partial class Startup
{
    public void Configuration(IAppBuilder app)
    {
        ConfigureAuth(app); //Exception is thrown here
    }
}

这是我的packages.config:

  <package id="Unity" version="3.5.1404.0" targetFramework="net45" />
  <package id="WebGrease" version="1.6.0" targetFramework="net45" />
</packages>

我尝试添加绑定重定向:

<dependentAssembly>
    <assemblyIdentity name="Microsoft.Owin.Security.OAuth" PublicKeyToken="31bf3856ad364e35"/>
    <bindingRedirect oldVersion="1.0.0.0-3.0.1.0" newVersion="3.0.1.0"/>
</dependentAssembly> 

无法理解为什么这不起作用,Visual Studio在3.0.1和3.0.1.0之间有区别吗？

我尝试删除obj和bin文件夹,清理项目并重建它们.

我尝试删除所有nuget包并恢复它们.

我尝试重新安装所有Owin软件包.

我使用Agent Ransack在我的整个源目录中搜索包含Microsoft.Owin.Security.OAuth的任何文件,但没有找到对版本2.0.0.0或除正确3.0.1.0之外的任何其他版本的引用.

我卡住了,有什么想法？

Answer 1

好吧,以防万一其他人最终遇到这个问题;

问题是该Microsoft.AspNet.Identity.Owin软件包依赖Microsoft.Owin.Security.OAuth于版本并且版本不匹配.

  <package id="Microsoft.AspNet.Identity.Core" version="1.0.0" targetFramework="net45" />
  <package id="Microsoft.AspNet.Identity.EntityFramework" version="1.0.0" targetFramework="net45" />
  <package id="Microsoft.AspNet.Identity.Owin" version="1.0.0" targetFramework="net45" />

显然,即使Microsoft.AspNet.Identity.Owin需要> = v2.0 Microsoft.Owin.Security.OAuth,但v3 + Microsoft.Owin.Security.OAuth会破坏兼容性(主要版本不一致).

在我更新了Microsoft.AspNet.Identity.Owin包及其相邻的家庭成员后Microsoft.AspNet.Identity.EntityFramework,Microsoft.AspNet.Identity.Core我删除了所有包,bin和obj文件夹并重建了解决方案.瞧!
