QUANTCONNECT COMMUNITY
Hi guys,
I'm having an issue running QuantConnect.Lean in Visual Studio. So far I've cloned the latest from git, built the solution without error, and tried running in Debug mode, with QuantConnect.Lean.Launcher as the Start-up Project.
I'm getting the follow exception:
Share New Research 
System.ArgumentException: 'Unable to locate any exports matching the requested typeName: QuantConnect.Queues.JobQueue
Parameter name: typeName'Any suggestions on what I've missed?
Regards,
Antonio.

Given that this is the code which throws the error, I think JobQueue was either built incorrectly or, more likely, something akin to:
https://github.com/QuantConnect/Lean/issues/15
Otherwise, did you change anything inside of Lean/Launcher/config.json?

Thanks for the reply, Aaron.
It does appear to be something very similar to the issue you linked, however I've run git clean -xdf, a solution clean and re-build, and still have this issue.
Is there anything else you could suggest? I'm using VS Enterprise 2019 Preview.

Hi Antonio,
Did QuantConnect.Queues project compile? It's odd that it didn't since the project that builds the Lean executable (QuantConnect.Launcher project) depends on it.
You might verify whether you got .Net Framework 4.6.2 installed as well since it might be a missing component in your system.
