VS2015开发的插件,VS2013不能安装

[weixin_38072900]

我使用VS2015开发了一个简单的插件，V2015正常安装运行，但是VS2013缺是
2016/12/1 13:19:17 - 正在开始将扩展安装到 Microsoft Visual Studio Ultimate 2013...
2016/12/1 13:19:17 - 安装错误: Microsoft.VisualStudio.ExtensionManager.MissingReferencesException: 无法安装此扩展，因为缺少以下引用:
- Visual Studio MPF 14.0
   在 Microsoft.VisualStudio.ExtensionManager.ExtensionManagerService.CheckForInstallBlockers(InstallableExtensionImpl extension, IInstalledExtensionList modifiedInstalledExtensionsList, Boolean isNestedExtension, Boolean& olderVersionInstalled)
   在 Microsoft.VisualStudio.ExtensionManager.ExtensionManagerService.InstallInternal(InstallableExtensionImpl extension, Boolean perMachine, Boolean isNestedExtension, IDictionary`2 extensionsInstalledSoFar, List`1 extensionsUninstalledSoFar, IInstalledExtensionList
modifiedInstalledExtensionsList, AsyncOperation asyncOp, UInt64 totalBytesToWrite, UInt64& totalBytesWritten, Boolean enforceCertificateCheckForUpgrade)
   在 Microsoft.VisualStudio.ExtensionManager.ExtensionManagerService.BeginInstall(IInstallableExtension installableExtension, Boolean perMachine, AsyncOperation asyncOp, Boolean enforceCertificateCheckForUpgrade)
   在 Microsoft.VisualStudio.ExtensionManager.ExtensionManagerService.InstallWorker(IInstallableExtension extension, Boolean perMachine, AsyncOperation asyncOp, Boolean enforceCertificateCheckForUpgrade)


但是我已经将source.extension.vsixmanifest文件里面依赖性里面的 Visual Studio MPF 14.0移除掉了
为什么还是不行？
