Just to get the ball rolling. Hoping to extent this from now on, especially if anyone find it useful.

Hello James,
Above code part is much helpful to me, but the only problem i see is when i try to assign the $arraylog to the $params.Loggers =$arraylog. Seeing the below error:
Exception setting "Loggers": "Cannot convert the "System.Collections.Generic.List1[Microsoft.Build.Framework.ILogger]" value of type "System.Collections.Generic.List1[[Microsoft.Build.Framework.ILogger, Microsoft.Build.Framework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a]]" to type
"System.Collections.Generic.IEnumerable`1[Microsoft.Build.Framework.ILogger]"."

   Could you please help me in converting the list $arraylog to ienumerable to proceed further.

Regards,
Niharika.

Can I Use it to compile a .sln project?
