Trust type provider

This post is to help people get out "not trust" problem when he accidentally click "Disallow" on the security dialog.

I always click "enable" button to trust the type provider DLL. But today I accidentally click "disallow".. :-(

The rescue is here

1. go to option under the tool
2. find "F# tools"
3. find "type providers"
4. on the right side of panel, you can find the DLL listed and you can check the checkbox to trust it.
