StackOverflow during ExchangeDeclareAsync. Client version 7.0.0

[plewam]

Hi,

I have switched my development branch to 7.0.0alpha1 out of curiosity. I really like the new async/ await functionality. I thought I might report some troubles I am having with it.
During startup of my application I declare an exchange (It might already exist on the broker). Previously I used the regular IModel.ExchangeDeclare() while I now use IChannel.ExchangeDeclareAsync().

await this.Channel.ExchangeDeclareAsync(myEchangeName, ExchangeType.Topic, durable: true, autoDelete: true);

Exception call stack

Stack overflow.

Hello!

I really appreciate you testing the alpha releases of version 7.0.0

Yes, this has been fixed in main already:

Hey, facing the same issue, hope new version will be released soon, thank you guys ))

[lukebakken]

@plewam @sulton-max

Please see this upcoming release - packages will be available in the next hour or so:
https://github.com/rabbitmq/rabbitmq-dotnet-client/releases/tag/v7.0.0-alpha.2

Team RabbitMQ and myself appreciate you taking the time to test these pre-releases! Please continue to do so and report any issues or questions you have.

[plewam]

@lukebakken No problem, I just applied the pre release to my dev environment and it started up fine and is processing messages like the 6.x production version does. I will continue to test :)
