[QCR615]

Hi, I am new with to Azure and .Net framework and following this link to setup the app on Azure:
https://docs.microsoft.com/en-us/azure/power-bi-embedded/power-bi-embedded-get-started-sample
While setting up power bi app I am getting below error:
-Package Manager Console: upadate-package ProvisionSample
Install-Package : Could not install package 'System.IdentityModel.Tokens.Jwt 5.0.0'. You are trying to install this
package into a project that targets '.NETFramework,Version=v4.5', but the package does not contain any assembly
references or content files that are compatible with that framework. For more information, contact the package author.At
