GitHub Issues

Pay attention

Please do not open an issue on GitHub, unless you have spotted an actual bug in MassTransit.

Use GitHub Discussions to ask questions, bring up ideas, or other general items. Issues are not the place for questions, and will either be converted to a discussion or closed.

This policy is in place to avoid bugs being drowned out in a pile of sensible suggestions for future enhancements and calls for help from people who forget to check back if they get it and so on.
