Hi friends,
I am trying to do crud operations using webapi in console application. I have followed this blog(rajeevpentyala.com/.../code-snippet-authenticate-and-perform-operations-using-d365-web-api-and-c) and did changes but i got An unhandled exception of type 'System.AggregateException' occurred in mscorlib.dll.
In this line "authResult = context.AcquireTokenAsync(serviceUrl, applicationId, credentials).Result;" I am getting error and while debugging i found username and password is null. can anyone help me.
This is the code I have written
