'IConfigurationSection' does not contain a definition for 'Get' and no accessible extension

Question

I created the JwtHelper class. I have been using it for a long time. However, when I updated the packages, I got an error in the following line;

The complete error message is as follows;

Severity Code Description Project File Line Suppression State Error CS1061 'IConfigurationSection' does not contain a definition for 'Get' and no accessible extension method 'Get' accepting a first argument of type 'IConfigurationSection' could be found (are you missing a using directive or an assembly reference?)

I found the solution. I'm writing here so you don't waste time.

Answer 1

Go to Nuget and download the "Microsoft.Extensions.Configuration.Binder" package.

Install-Package Microsoft.Extensions.Configuration.Binder -Version 5.0.0

I still can't understand why sometimes it perfectly works with just Microsoft.Extensions.Configuration, without a Binder package, but in other cases, Microsoft.Extensions.Configuration.Binder is the only way to fix a compiler error. – Ihs
