Rebus - System.MissingMethodException : Method not found: 'System.Threading.Tasks.Task Rebus.Bus.IBus.Send'

Question

When calling SendRequest using Rebus.Async, I get this error:

System.MissingMethodException : Method not found: 'System.Threading.Tasks.Task Rebus.Bus.IBus.Send(System.Object, System.Collections.Generic.Dictionary`2)'.

How can I resolve this?

Answer 1

Check your NuGet package versions. Make sure one isn't a prerelease version while the others are stable.

For me, I had installed a Rebus extension that depended on the prerelease version of another Rebus package. Updating all Rebus packages to the latest (prerelease where applicable; latest stable otherwise) versions fixed the issue.
