based on you current JSON the classes have to look like:

public class Dev
{
    public string resourcegroup { get; set; }
    public string storageaccount { get; set; }
    public string azuresqlserver { get; set; }
    public string container { get; set; }
    public string sourcesqlserver { get; set; }
}

public class Qa
{
    public string resourcegroup { get; set; }
    public string storageaccount { get; set; }
    public string azuresqlserver { get; set; }
    public string container { get; set; }
    public string sourcesqlserver { get; set; }
}

public class Example
{
    public Dev Dev { get; set; }
    public Qa qa { get; set; }
}

i generated them based on you JSON here

deserializing of your input JSON with the generated classes would look like:

var obj = JsonSerializer.Deserialize<Example>(json );
