Hey @herdma,

Thanks for raising this.

Any chance you can provide more information about your runtime? You provided .NET 4.6.1 but version Microsoft.Graph 4.20.0 targets a minimum version of 4.6.2 on .Net Framework

Hey @andrueastman

Thanks, I created a new project with target framework .NET 4.6.2 and it works now. I chose 4.6.1 previously because the README mentions this:

The Microsoft Graph .NET Client Library targets .NetStandard 2.0 and .Net Framework 4.6.1.

Thanks for pointing that out. That is an error in the Readme.

Created #1276 to resolve this.
