Question

在XBAP下载的最后，我得到了错误跟踪。我已经尝试使用Procmon和VS2013-debugger找出遗漏了什么。但是，到目前为止我还没有成功......有任何提示吗？

在Fidder中，我为所有下载的文件获得了200秒......

好的，问题是缓存大小的默认限制，即250MB。这就是我必须做的事情：

添加/更改HKEY_CURRENT_USER\Software\Classes\Software\Microsoft\Windows\CurrentVersion\Deployment\OnlineAppQuotaInKB，这是一个DWORD值，表示以千字节为单位的缓存大小。例如，为了将缓存大小增加到500MB，我将此值设置为512000。
