Master User Authentication - Power BI Embedded

Hi 

 

I am using Master User authentication type to embed my power bi dashboard in my ASP.NET application, so i set up my Power BI Embedding environment through below link.

https://app.powerbi.com/embedsetup/AppOwnsData

 

i donwloaded the sample application from Power BI and filled application id, workspace id, report id, Pbi pro account username, Pbi password. 

 

once i run the application i get error message "Object reference not set to an instance of an object" and no access token details is retuned in below line code 

 

authenticationResult = authenticationContext.AcquireTokenAsync(ResourceUrl, ApplicationId, credential).Result;

 

i troubleshooted the issue and and tested whether there is a value of the access token or not using below code. 

string accesstoken = authenticationResult.AccessToken;

The string returned below error message. 

 

error CS1703: Multiple assemblies with equivalent identity have been imported: 'System.Runtime.dll' and 'System.Runtime.dll'. Remove one of the duplicate references.

 

what is the cause of the error message and how to fix it?
