由于我用的是C#语言，没法调试，没法解决这个问题，请您解决一下 |
|
The problem was solved at #710. You can try to use this docker image https://hub.docker.com/r/coolbeevip/servicecomb-pack, Or build your own version based on the master branch docker pull coolbeevip/servicecomb-pack:0.7.0-all-in-one |

楼主 我能问一下C# 使用的问题吗 在线等 目前我也是.net 5.0 碰到问题了 |
楼主 能支持一下吗 |
