Unsupported messageType: comm_info_request on document creation/opening #95

Description

I'm getting this error any time I'm creating or opening the IFSharp notebook. After restart kernel works properly, except Nuget doesn't work for any package (for example NuGet error: Unable to find package 'Newtonsoft.Json'), not sure if these two issues are connected. Windows 10, v3.0.0-alpha3
