Hello Sonya,
I don’t specialize in ASP.NET so I’m not familiar with that error.
Maybe the following answers to that question will help you:

https://forums.asp.net/t/2155031.aspx?The+connection+string+MydbContext+in+the+application+s+configuration+file+does+not+contain+the+required+providerName+attribute+

If that doesn’t help you, please send me the archive with your project so that I can reproduce the issue locally and check if there is something wrong with the configuration.
