How to find Assertion key value?

Question

Hi, 
I am referring MSDN article for Management Libraries for .NET to access my Azure AD account.
I followed all steps from article, but when my application execution starts it gives an error
"An unhandled exception of type 'Microsoft.IdentityModel.Clients.ActiveDirectory.AdalServiceException' occurred in Microsoft.IdentityModel.Clients.ActiveDirectory.dll
Additional information: AADSTS90014: The request body must contain the following parameter: 'client_secret or client_assertion'."
c# block where I caught in error-- 
 AuthenticationResult result = context.AcquireToken(
                      ConfigurationManager.AppSettings["apiEndpoint"],
                         ConfigurationManager.AppSettings["clientId"],
                        new Uri(ConfigurationManager.AppSettings["redirectUri"]));
my context variable as below
var context = new AuthenticationContext(string.Format(
                  ConfigurationManager.AppSettings["login"],
                  ConfigurationManager.AppSettings["tenantId"]));
and when I am trying to add client_secrete key to code 
 AuthenticationResult  result = context.AcquireToken(
                      ConfigurationManager.AppSettings["apiEndpoint"],
                       new ClientCredential("*******", "******"),
                         new UserAssertion("*****", "client_credentials", "*****"));
throws an error
An unhandled exception of type 'Microsoft.IdentityModel.Clients.ActiveDirectory.AdalServiceException' occurred in Microsoft.IdentityModel.Clients.ActiveDirectory.dll
Additional information: AADSTS50027: Invalid JWT token. AADSTS50027: Invalid JWT token. Token format not valid.
please tell me proper solution where I making mistake and also help to find Assertion key value for application which are added on Azure AD portal.
thanks,
Yogesh
