Expected behavior

Dotnet SDK to encode pound character so queries to external users work.

Actual behavior

Dotnet SDK doesn't encode pound character which results in a null return value.

Steps to reproduce the behavior

1. Invite an external user to your organization (in my case I invited the user [email protected] to the org baywet.onmicrosoft.com)
2. Try to query the external user like this

var user = await client.Users["vincent_2tolead.com#EXT#@baywet.onmicrosoft.com"].Request().GetAsync(); // this will not return the user
var user2 = await client.Users["vincent_2tolead.com%23EXT%[email protected]"].Request().GetAsync(); // this will return the user

Thank you @baywet for bringing this up.

@MIchaelMainer any updates on this? I'm running into this as well with the encoding for mailbox extensions ([email protected]). The query fails, if I run trace it via App Insights and run the Graph query manually replacing + for %2B it works.

Closing this one for now as this is resolved with V5 of the SDK which uses URL templates that automatically encode the URL segments based on the HTTP specification
