Solving System.Data.SqlClient Issues in Visual Studio Code on Debian 9.9

When diving into .NET Core development on Debian, you might run into some hiccups, especially when using Visual Studio Code. One such challenge can arise when querying a SQL Server database with System.Data.SqlClient. A common issue many developers face includes errors related to deprecated classes such as SqlConnection and SqlCommand, along with confusion regarding package versions. In this guide, we’ll explore how to resolve these issues so you can get back to building powerful database-driven applications.

The Problem

While working on a C# console application in Visual Studio Code, you might encounter errors that suggest SqlConnection and SqlCommand are deprecated. You may also receive messages indicating that you need to use a nonexistent version of System.Data.SqlClient, leading to confusion and frustration.

This problem can impede your development process, especially if you’re eager to query a database using your application. So, how can you fix this?

Solution: Adding the Correct Package

The good news is that resolving this issue is straightforward. You need to ensure that the System.Data.SqlClient package is correctly added to your project. This step is essential because without the package, your C# application will not recognize the required classes and methods for SQL Server interactions.
