I provided the following answer wich I'm not sure if it sh'd be the complete satisfying asnwer

                       -Excerpt fom prosolo written test prep question bank.-

Question: A magenta dashed line surrounds certain uncontrolled airports. What does this indicate

and what is its significance to VFR pilots?

Answer: As tower closure depends on published times this class E airspace will vary also depending on the published airspace classification stated in the chart supplements.

The only thing for VFR pilots that'll change is the cloud and visibility requirements in effect as well as for comunicating the CTAF when airport is closed for position reporting.

    The question asks about uncontrolled which is really called non-towered airports so how does a tower closure play into this? Need to go study the legend some more about dashed magenta around an airport.

    As I read 3−2−6. Class E Airspace from the AIM airport closure times.

    But there are two sorts of dashed lines in the legend a thick and thin one, wich do you mean? National security dashed line or Class E dashed line?

    Danny,

    At most non-towered airports, they are located in class G up to the base of class E airspace which starts at 700 AGL or 1200 AGL. When you see the dashed magenta, it indicates that class E airspace starts at the surface. In class G airspace below 1200 AGL during the day, it is a beautiful VFR day anytime the visibility is 1 SM or greater. When an airport has instrument approaches, the class E is lowered to 700 AGL, so at such airports, anytime the visibility is 1 SM or greater, there can be a mix of VFR and IFR aircraft in the pattern. If the airlines are regularly scheduled into an airport, the class E is from the surface and any VFR aircraft are prohibited when the visibility is less than 3 SM and cloud separation of 500 feet below, 1000 feet above, and 2000 feet laterally are also imposed. That way, there isn’t mixing of VFR and IFR traffic in the pattern until the conditions are quite good where IFR and VFR traffic can separate themselves visually. Without class E to the surface, you can pop out of the clouds and be immediately confronted with a legal VFR aircraft.

    Are you talking about a Class E extension at a towered airport?
