I am getting this exception when using Hangfire with Dapper.Contrib

System.MissingMethodException

Is this a bug or Hangfire simply will not work with Dapper? I have used it with ServiceStack.Ormlite and it was working fine, but it is no longer open source so that is why I am migrating to Dapper.

I noticed there is another version of Dapper in Hangfire.SqlServer assembly, why is this so? I am guessing this is causing the conflict?

Looks like this is a Dapper or Dapper.Contrib issue, or an issue with the code (see the call stack, something is wrong with the parameter). Hangfire does not add anything here, consider it as just a separate thread.

Regarding Hangfire.SqlServer, Dapper is merged and internalised into Hangfire.SqlServer.dll assembly, so no versioning issues could appear.
