httprequest depreciation - Later ASP.Net Core versions and httpclient

[oaktechnology]

We currently use hawknet on asp.net 4.8 and am switching to .Net Core 6 and Blazor and as part of this the httprequest has been depreciated so we have switched to httpclient instead but I am struggling to get the code to work and the issue seems to be down to the hawk signing.
I don't suppose you have any sample code for httpclient do you as it would be a great help and worth having the updated example.

Thank you
Simon
