We are upgrading Bot Builder dll from 3.11.0 to Latest stable version 3.15.2.2. This dll has a dependency on System.IdentityModel.Tokens.Jwt.
The current version of System.IdentityModel.Tokens.Jwt is 4.0.40306.1554 and after an upgrade it is 5.1.4.0.
Which is not supporting our current implementation for Authentication related TokenValidationParameters.
