Minimal steps to reproduce

go to ReadMe

Expected/desired behavior

• show for each authentication specific property listed in the files below, those relevant fields referencing the azure b2c portal (best would be a printscreen I think), so wrong setup of the project can be avoided.
• Propertiy namings in the blazor project are difficult to find in azure because of different namings! This cuold be improved.
• Proper understanding helps to improve security! Reading hundreds of pages of complex authentication docs from microsoft and azure is not practicable. Make setup as simple as possible with as less configuration as possible.
