的类型初始“Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment'引发了异常 [英] The type initializer for 'Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment' threw an exception

问题描述

我想使用Windows Azure的缓存来存储会话在MVC4应用。我建立了下面的链接步骤的应用但是当我尝试使用下面code线进行数据高速缓存的对象。

 数据高速缓存缓存=新的数据高速缓存（默认）;
 

发生错误：

  

Microsoft.WindowsAzure.ServiceRuntime.dll没有发现或版本   不匹配的，我更新了Windows Azure的模拟器版本为2.0.0，并   使用的NuGet安装WindowsAzure.Caching包版本2.0.0.0   包安装程序。现在错误更改为的类型初始   Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment'抛出   例外。

我使用 Windows 8中使用VS2012和Windows Azure的模拟器版本2.0.0。

我会感激，如果任何人都可以帮助我在此。

解决方案

我从Azure的SDK 2.3迁移以SDK 2.4 时，经历了这一点。

我注意到迁移自动固定在服务运行时都引用了我的web和辅助角色，即

  C：\ Program Files文件\微软的SDK \ Windows Azure的\ .NET SDK \ V2.3 \文献\ Microsoft.WindowsAzure.ServiceRuntime.dll
 

更改为：

  C：\ Program Files文件\微软的SDK \的Azure \ .NET SDK \ V2.4 \文献\ Microsoft.WindowsAzure.ServiceRuntime.dll
 

但是从引用的本次大会网络/辅助角色中引用的任何组件没有更新，所以我不得不做手工。

此外，我不得不更新的web.config和app.config中的条目引用2.4.0.0

 ＆LT; dependentAssembly＆GT;
    ＆LT; assemblyIdentity名=Microsoft.WindowsAzure.ServiceRuntime公钥=31bf3856ad364e35文化=中性/＆GT;
     ＆LT; bindingRedirect oldVersion =0.0.0.0-2.4.0.0NEWVERSION =2.4.0.0/＆GT;
＆LT; / dependentAssembly＆GT;
 

I am trying to use Windows Azure Caching to store sessions in a MVC4 application. I build a application following steps from Link but when i try to make object of DataCache using below code line.

DataCache cache = new DataCache("default");

Errors occurs:

Microsoft.WindowsAzure.ServiceRuntime.dll not found or version mismatched, I updated my Windows Azure Emulator version to 2.0.0 and install WindowsAzure.Caching package version 2.0.0.0 using NuGet package installer. Now the error changes to "The type initializer for 'Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment' threw an exception."

I am using Windows 8 with VS2012 and Windows Azure Emulator version 2.0.0.

I will grateful if anyone can help me on this.

解决方案

I experienced this when migrating from Azure SDK 2.3 to SDK 2.4.

I noticed the migration automatically fixed all references to the service runtime for my web and worker roles, i.e.

C:\Program Files\Microsoft SDKs\Windows Azure\.NET SDK\v2.3\ref\Microsoft.WindowsAzure.ServiceRuntime.dll

changed to:

C:\Program Files\Microsoft SDKs\Azure\.NET SDK\v2.4\ref\Microsoft.WindowsAzure.ServiceRuntime.dll

However any assemblies referenced from the web/worker roles that referenced this assembly didn't update so I had to do it manually.

In addition I had to update the web.config and app.config entries to reference 2.4.0.0

<dependentAssembly>
    <assemblyIdentity name="Microsoft.WindowsAzure.ServiceRuntime" publicKeyToken="31bf3856ad364e35" culture="neutral" />
     <bindingRedirect oldVersion="0.0.0.0-2.4.0.0" newVersion="2.4.0.0" />
</dependentAssembly>
