C#-自动更新Visual Studio扩展

我试图使扩展程序在将新版本推送到Visual Studio Gallery时自动进行自我更新.关于如何实现这一目标,有一些指南,但它们已有两年历史,可能并不适用.

对于初学者,我尝试按以下方式查询IVsExtensionRepository：

var _extensionRepository = (IVsExtensionRepository)Microsoft.VisualStudio.Shell.Package.GetGlobalService(typeof(SVsExtensionRepository));

var query = _extensionRepository.CreateQuery<VSGalleryEntry>(false, true)
                .OrderByDescending(n => n.Ranking)
                .Skip(0)
                .Take(25) as IVsExtensionRepositoryQuery<VSGalleryEntry>;

query.ExecuteCompleted += Query_ExecuteCompleted;
query.ExecuteAsync();

在Query_ExecuteCompleted处,我从服务器接收到异常：“远程服务器返回错误：(400)错误的请求.”

提供了堆栈跟踪：

服务器堆栈跟踪：
    在System.Runtime.AsyncResult.End [TAsyncResult](IAsyncResult结果)处
    在System.ServiceModel.Channels.ServiceChannel.SendAsyncResult.End(SendAsyncResult结果)
    在System.ServiceModel.Channels.ServiceChannel.EndCall处(字符串操作,Object []输出,IAsyncResult结果)
    在System.ServiceModel.Channels.ServiceChannelProxy.InvokeEndService(IMethodCallMessage methodCall,ProxyOperationRuntime操作)
    在System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage消息)

该服务托管于：https://visualstudiogallery.msdn.microsoft.com/services/dev12/extension.svc

有谁知道我如何创建一个Visual Studio扩展,该扩展会自动从Visual Studio画廊自动更新？通过IVsExtensionRepository还是手动进行？

解决方法:

编辑：现在,在Visual Studio 2015中,扩展会自动下载.

因此,我已经完全放弃了查询IVsExtensionRepository.我不确定为什么,但是它构造的查询一定存在一些内部问题.我使用ErikEJ的建议项目查询了相同的服务,并且运行良好.

但是,我不想从WSDL构造服务,因为SQLCeToolbox看起来已经完成了.相反,我使用了IVsExtensionRepository,但是避免了CreateQuery()方法.

附件是我更新VSPackage的方法.您需要用软件包的信息替换任何GUID或软件包的特定名称.

注意以下代码中有一个“陷阱”：

请注意,CodeConnectRepositoryEntry仅实现DownloadUrl.更新VSPackage时,这是所有人必须担心的,因为它允许我们下载新的软件包.可以在VSPackage的VSGallery页面上找到此URL.

但是：您必须按如下所示修剪URL：

http://visualstudiogallery.msdn.microsoft.com/c0c2ad47-957c-4e07-89fc-20996595b6dd/file/140793/4/CodeConnectAlpha.vsix

至：

http://visualstudiogallery.msdn.microsoft.com/c0c2ad47-957c-4e07-89fc-20996595b6dd/file/140793/

上面的/ 4 /代表第四次上传.通过完全删除它,Visual Studio Gallery将下载最新版本.
