我正在开发一个ASP.NET MVC3 Web应用程序,它使用Entity Framework 4.1和MySQL。
本地一切运行良好,但是当我将解决方案部署到Web主机时,它会给我以下错误消息:
System.Security.SecurityException:请求失败。在 System.Security.CodeAccessSecurityEngine.ThrowSecurityException(RuntimeAssembly asm,PermissionSet被授予,PermissionSet被拒绝, RuntimeMethodHandleInternal rmh,SecurityAction动作,对象需求, IPermission permThatFailed)at System.Security.CodeAccessSecurityEngine.ThrowSecurityException(对象 assemblyOrString,PermissionSet被授予,PermissionSet被拒绝, RuntimeMethodHandleInternal rmh,SecurityAction动作,对象需求, IPermission permThatFailed)at System.Security.CodeAccessSecurityEngine.CheckSetHelper(PermissionSet中 授予,PermissionSet拒绝,PermissionSet要求, RuntimeMethodHandleInternal rmh,Object assemblyOrString, SecurityAction动作,布尔值throwException)at System.Security.PermissionSetTriple.CheckSetDemand(PermissionSet中 demandSet,PermissionSet& alteredDemandset, RuntimeMethodHandleInternal rmh)at System.Security.PermissionListSet.CheckSetDemand(PermissionSet pset, RuntimeMethodHandleInternal rmh)at System.Security.PermissionListSet.DemandFlagsOrGrantSet(Int32标志, PermissionSet grantSet)at System.Security.CodeAccessSecurityEngine.ReflectionTargetDemandHelper(的Int32 权限,PermissionSet targetGrant,CompressedStack securityContext)at System.Security.CodeAccessSecurityEngine.ReflectionTargetDemandHelper(的Int32 permission,PermissionSet targetGrant)失败的操作是: 需求失败的第一个权限的类型是: System.Security.PermissionSet
我的网站.Config:
<connectionStrings>
<add name="MySqlMembershipConnection" connectionString="Data Source=localhost;userid=userName;password=passw0rd;database=tv;" providerName="MySql.Data.MySqlClient,Version=6.3.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"/>
<add name="TvEntities" connectionString="metadata=res://*/Entities.Model.csdl|res://*/Entities.Model.ssdl|res://*/Entities.Model.msl;provider=MySql.Data.MySqlClient;provider connection string="server=127.0.0.1;port=3351;User Id=userName;password=passw0rd;Persist Security Info=True;database=tv"" providerName="System.Data.EntityClient" />
</connectionStrings>
<system.data>
<DbProviderFactories>
<clear />
<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL"

Trustlevel处于中等状态。
有什么想法吗?

尝试使用较新版本的连接器。它是reported as a bug,应该在6.3.7和6.4.1中修复。

添加对System.Web.Providers的引用。如果程序集在本地不可用,请使用NuGet Package Manager按如下方式安装它:
PM> Install-Package System.Web.Providers
还要在web.config文件中验证以下条目已添加到配置文件部分
<roleManager defaultProvider="DefaultRoleProvider">
<providers>
<add name="DefaultRoleProvider" type="System.Web.Providers.DefaultRoleProvider,
System.Web.Providers, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=31bf3856ad364e35"
connectionStringName="DefaultConnection" applicationName="/" />
</providers>
</roleManager>
然后您可以重建应用程序并执行它。
