.NET MVC 5 OData自定义操作绑定到实体的版本

Question

在.NET MVC 4/5中，我可以创建绑定到实体的自定义操作。例如

var builder = new ODataConventionModelBuilder(); 
... 
var testAction = builder.EntityType<MyEntity>().Action("Test"); 
testAction.Returns<bool>(); 
testAction.Parameter<int>("testParameter"); 
... 
return builder.GetEdmModel() 

但是，如何实现绑定到使用VersionedODataModelBuilder的实体的版本化自定义操作？例如

var builder = new VersionedODataModelBuilder(config) 
{ 
    ModelConfigurations = 
    { 
     new TestModelConfiguration() 
    } 
    ... 
    // BAD: property EntityType does not exist on the builder object. 
    var testAction = builder.EntityType<MyEntity>().Action("Test"); 
};

我能够通过以下方法在路线上成功创建自定义动作和自定义功能。

我需要将我的问题代码添加到TestModelConfiguration.cs中，使ODataModelBuilder对象可用。

的web.config：

<add name="ExtensionlessUrlHandler-Integrated-4.0" path="/*" verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" /> 

TestModelConfiguration.cs：

private EntityTypeConfiguration<RunViewModel> ConfigureCurrent(ODataModelBuilder builder) 
{ 
    var pingFunction = builder.EntityType<RunViewModel>().Function("Ping"); 
    pingFunction.Returns<bool>(); 
    pingFunction.Parameter<int>("test"); 
    pingFunction.Namespace = "Function"; 

    var pongAction = builder.EntityType<RunViewModel>().Action("Pong"); 
    pongAction.Returns<bool>(); 
    pongAction.Parameter<int>("test"); 
    pongAction.Namespace = "Action"; 

TestController.cs：

public class RunController : BaseODataController 
{ 
    [HttpGet] 
    [ODataRoute("Test({key})/Function.Ping(test={test})")] 
    public bool Ping([FromODataUri] int key, int test) 
    { 
     return true; 
    } 

    [HttpPost] 
    [ODataRoute("Test({key})/Action.Pong")] 
    public IHttpActionResult Pong([FromODataUri] int key, ODataActionParameters parameters) 
    { 
     return Ok(true); 
    }
