处理已安装的应用程序事件.替换上下文权限不起作用 [英] Handle app event Installed . Replace permissions for context isn't working

问题描述

大家好！

当我安装或升级mu app时，我想创建组，或者如果存在则替换权限.但是，每当我使用应用程序事件接收器时，我什至无法在共享点上安装我的应用程序.如果我不使用它们，则该应用程序会很好地安装，并列出项目事件接收器 也可以.

When i install or upgrade mu app i want to create groups or if exist to replace permissions. However whenever i use the app event receivers, i can't even install my app on sharepoint. If i don't use them the app installs just fine , and list item event receivers work as well.

当我启用了应用程序事件接收器时，我也无法调试.我不知道为什么，但是Visual Studio在提供凭据后卡住了

Also i can't debug when i have enabled the app event receivers. I don't know why but visual studio is stuck after providing credentials

这是我正在使用的代码:

Here is the code i'm using :

using System.Collections.Generic;

using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.EventReceivers;

    /// <summary>
    /// Handles app events that occur after the app is installed or    upgraded, or when app is being uninstalled.
    /// </summary>
    /// <param name="properties">Holds information about the app event.</param>
    /// <returns>Holds information returned from the app event.</returns>
