  - by MarceloRamires

  I have an ASP.NET project which has already some custom fields in it's web.config file. I've added in it three more fields and used them in my changes, and it's working great.

How do I check the existance of fields in web.config, and in case of not finding it, how do I add it permanently to the web.config ? Thank you

• What's the difference between <% and <%:

  - by Blub

  Hi, I couldn't find anything through Google, I suppose the search terms are too much to handle. The VS built-in help only explains <%, which is just embedded code. There is no mention of <%: EDIT: My book says, that the only difference is that <%: returns a MvcHtmlString. Why do we need an extra symbol for <%: just to return something? Thanks for any help! It would really help me to understand asp.net.
