Can someone give example how to pass JSON type as parameter to SQL Server 2016 stored procedure using ADO.Net in C# ASP.Net Core Web Api project ? I want to see example of SQL
For a simple example that shows the C# and the SQL, please see: https://chris.koester.io/index.php/2018/03/21/load-json-into-sql-server-using-a-stored-procedure-and-csharp/
You probably have some higher level data layer approach in your C#, like with EF or something, but this will let you get a simple test setup using a good ol' ADO.Net SQLCommand.
