For reference, this is an existing Feature Request <https://issuetracker.google.com/35901085> in the Public Issue Tracker <https://cloud.google.com/support/docs/issue-trackers>for this App Engine limitation. Since App Engine Standard runs on containers, its current architecture implementation was strictly designed around HTTP interfacing, and not sockets. There is also an open feature requests for App Engine sockets support <https://issuetracker.google.com/35886348>, and there is an early access request form <https://docs.google.com/forms/d/e/1FAIpQLSf7KBmhhYTfJBctmelgEQuBQM2nYFvGo3o2_lBY0iFmuKbcUw/viewform> (for both Standard and Flex).
If you are using App Engine Flexible, I was able to find this example <https://github.com/GoogleCloudPlatform/dotnet-docs-samples/blob/master/appengine/flexible/CloudSql/app.yaml> working with TCP connection to Cloud SQL in .Net. All further communications about this request should continue in the open feature request <https://issuetracker.google.com/35901085>. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
