C# Bot Framework 和最大上传限制

Question

Botframework 和 C# 存在同样的问题，尝试上传针对自定义视觉服务查询的图像。任何大于 4MB 的图像都不会发布，我会收到错误代码 500 内部服务器错误。请记住，它使用 botframework-emulator 在本地工作。

我已经尝试编辑 php.ini(默认情况下最大上传大小设置为 8MB)

channel 对上传大小有自己的限制。例如 Skype

There are size limits to files, and some types of files may require separate software or an app to view them. As long as your friend has enough storage space, they can access and save any files you send them for 30 days. What is the file size limit in Skype? There is a 300 MB file size limit on shared files
