Don't know what this @ symbol is doing in this code

Question

Hi Sololearn Fam,

I am working on some break and fix projects at work. I am seeing the @ symbol before the { symbol and also I see the @* symbols before the <script src.........> tag.

What is the @ and @* doing here?

See the code below.
@{
string cndUrl = "https://d16mlsnlscorep.cloudfront.net/prod";

}
@*<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>*@
@*<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha384-tsQFqpEReu7ZLhBV2VZlAu7zcOV+rXbYlF2cqB8txI/8aZajjp4Bqd+V6D5IgvKT" crossorigin="anonymous">

Answer 1

I think the @ sign has to do with decorators:
