Not able to access Bigquery dataset from .net app - google-bigquery

Question

I am new to GCP and have created a Project in GCP which has a service account with a principal associated with it.The principal has role of editor , owner and viewer. I have created a dataset which contains a table which i am not able to access from .net application.
Steps used to connect to read data from table :
1.Created service account to authenticate Api requests
2.Created key,json file which will be used by .net application to connect to the datasets(gcloud iam service-accounts keys create ~/key.json)
3.
using Google.Apis.Auth.OAuth2;
using Google.Cloud.BigQuery.V2;
Console.WriteLine("Hello, World!");
string dir = Directory.GetParent(Directory.GetCurrentDirectory()).Parent.Parent.FullName + "\\"+"currency-342912-7c734b3fad06.json";
GoogleCredential credential = GoogleCredential.FromFile(dir);
var client = BigQueryClient.Create("currency-342912", credential);
var table = client.GetTable("bigquery-public-data", "austin_311", "311_service_requests");
var sql = $"SELECT * FROM {table} LIMIT 10";
var results = client.ExecuteQuery(sql,parameters:null);
getting the below error :
Google.GoogleApiException: 'Google.Apis.Requests.RequestError
Access Denied: Project bigquery-public-data: User does not have bigquery.jobs.create permission in project bigquery-public-data
But user has browser, editor , owner , viewer all the permissions

Answer 1

As per the error in the question above -"Access Denied: Project bigquery-public-data: User does not have bigquery.jobs.create permission in project bigquery-public-data"
it is mentioned to have the role "bigquery.jobs.create" so i applied this role at the project level and the only area left was the service account , i applied this role to the service account and this started working
