IBAutomater IOException trying to delete IBAutomater.log

[omidkrad]

This always happens when running the project locally.

ibgateway version: 1019
In Launcher project reference the following nuget packages:

• QuantConnect.Brokerages.InteractiveBrokers
• QuantConnect.Brokerages.InteractiveBrokers.ToolBox
  (latest version is 2.5.16517 for both)

In config.json set the following settings:

  "environment": "live-interactive",
  "data-provider": "QuantConnect.Lean.Engine.DataFeeds.DownloaderDataProvider",
  "data-downloader": "QuantConnect.ToolBox.IBDownloader.IBDataDownloader",

Run the Launcher

I tried to link QuantConnect.Brokerages.InteractiveBrokers by project reference instead of package. The project QuantConnect.Brokerages.InteractiveBrokers references QuantConnect.IBAutomater by project.
In QuantConnect.IBAutomater project I tried to put the line that tries to delete IBAutomater.log in try/catch, but for some reason after doing this and running the project only once, IB Gateway stops working altogether. Even trying to run IB Gateway manually won't work and ibgateway process won't load at all. When reverting changes and linking QuantConnect.Brokerages.InteractiveBrokers by package instead of by project, and running the Launcher, then IB Gateway starts again, with the exception happening again:

System.IO.IOException: The process cannot access the file 'C:\Jts\ibgateway\1019\IBAutomater.log' because it is being used by another process.
