== Sensitive Code Example

----
public void Foo(DbContext context, string query, string param)
{
    string sensitiveQuery = string.Concat(query, param); 
    context.Database.ExecuteSqlCommand(sensitiveQuery); // Sensitive
    context.Query<User>().FromSql(sensitiveQuery); // Sensitive

    context.Database.ExecuteSqlCommand($"SELECT * FROM mytable WHERE mycol={value}", param); // Sensitive, the FormattableString is evaluated and converted to RawSqlString
    string query = $"SELECT * FROM mytable WHERE mycol={param}";
    context.Database.ExecuteSqlCommand(query); // Sensitive, the FormattableString has already been evaluated, it won't be converted to a parametrized query.
}

public void Bar(SqlConnection connection, string param)
{
    SqlCommand command;
    string sensitiveQuery = string.Format("INSERT INTO Users (name) VALUES (\"{0}\")", param);
    command = new SqlCommand(sensitiveQuery); // Sensitive

    command.CommandText = sensitiveQuery; // Sensitive

    SqlDataAdapter adapter;
    adapter = new SqlDataAdapter(sensitiveQuery, connection); // Sensitive
}

== Compliant Solution

----
public void Foo(DbContext context, string query, string param)
{
    context.Database.ExecuteSqlCommand("SELECT * FROM mytable WHERE mycol=@p0", param); // Compliant, it's a parametrized safe query
}
