Andrej Tozon blogs about ASP.NET Map Control which was released recently.
According to Andrej in his blog post, “Working with the control appears to be easy. It took me about 15 minutes [including Tools’ download+setup] to port the previous version to use this new control. No RTFM, just drag and drop, set properties and copy/modify some relevant code. And still, the current implementation consumes only small part of functionality this control offers, leaving a lot of space for additional enhancements.”
Andrej created an application where it captures weather data from National Environmental Agency and display them on map as custom push pins. Andrej is going to post live example after some time.
