Question

I created an xml file in C#, but there is an annoying thing that when i open the file there is a yellow message from windows on the top of the window that says its trying to protect me, and ask me if i trust this file. is there a way to create the file so the message won’t show up?

Answer 1

You need to digitally sign the XML document if you want to get the trusted behavior out of it (i.e. no yellow warning bar). Below is how to do that (you’ll need a digital certificate from a trusted root authority though, like Verisign).

Edit: If you don’t have a signing certificate from Verising etc. you can use a workaround like this:

go into Internet Options > Advanced
then down to the Security section, and
tick the box for “Allow active content
to run in files on My Computer*”
