Script execution error and SQL72014 .NetSqlClient data provider error (Azure sql database and .net web api)

I am working on azure sql database and .net web api. I have access only to staging database and added two new columns and trying to get access the information from other tables. when I open the src project and build it, it gives me an error of Script execution error and SQL72014 .NetSqlClient data provider error. How can I remove these errors? Thank you in advance.
