编辑:现在在 Visual Studio 2015 中,扩展会自动下载。
所以我完全放弃了查询IVsExtensionRepository
. 我不知道为什么,但它构造的查询一定存在一些内部问题。我使用 ErikEJ 建议的项目查询了相同的服务,它运行良好。
但是,我不想从 WSDL 构建服务,因为 SQLCeToolbox 似乎已经完成了。相反,我使用了IVsExtensionRepository
,但避免了该CreateQuery()
方法。
附件是我更新 VSPackage 的方法。您需要将任何 GUID 或包特定名称替换为包的信息。
注意以下代码中有一个问题:
请注意,CodeConnectRepositoryEntry
仅实现DownloadUrl
. 更新 VSPackage 时,这是所有必须担心的,因为它允许我们下载新包。可以在 VSPackage 的 VSGallery 页面上找到此 URL。
但是:您必须按如下方式修剪 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 库将下载最新版本。
