For .NET Framework:
host start --pause-on-error
Fails to start with an error that I can't see because the terminal window disappears to fast.
For .NET Core:
%AppData%\..\Local\Azure.Functions.V2.Cli\2.0.1-beta\Azure.Functions.Cli.dll host start --pause-on-error
Getting error:
Microsoft.Azure.WebJobs.EventHubs: Could not load type 'Microsoft.Azure.WebJobs.FuncAsyncConverter' from assembly 'Microsoft.Azure.WebJobs.Host, Version=3.0.0.0, Culture=neutral, PublicKeyToken=null'.
