Build windows workflow activities for Office365 using C# and nuget package Microsoft.Graph. For authentication, you can use [login to view URL], if that makes it easy.
I am using Windows workflow activities just for testing only, eventually these activities will be integrated in a custom workflow system.
I need activities for the following Office 365 features, grouped as:
save file as..
find in files
add event, location, atendee
read cell, column, row, range
new, delete, update, get task,
I have attached a sample activity for send email.
