Rebuild Orchard.Web in preparation for running it from Visual Studio.
Run Orchard.Web from Visual Studio. Enable the BigFont.Maps module from the Dashboard interface.
Stop the running project in Visual Studio in preparation for modifying the code.
Commit the .sdf file which apppears to have changed itself somehow.
Add the UpdateFrom1() method to the migration.cs class file because this transforms the content-part into a widget.
Build BigFont.Maps and rebuild Orchard.Web in preparation for testing the new Widget.
Find and replace BigFont.Maps with Maps throughout what was the BigFont.Maps project. Also, change the project name to just Maps. Also, edit the Maps.csproj file and replace BigFont.Maps with just Maps. This appears to be necessary for Orchards MVC engine to find the Map_Part properly.
Add a Map Widget to the Message zone of the home page of Garden Faire using the Wdgets dashboard.
Delete the Maps project on which I have been working, then rebuild the solution in an attempt at startin again from scratch.
Get the BigFontMaps Module/Content-Part/Widget working by renaming the whole thing BigFontMaps insteast of either Maps or BigFont.Maps. This was necessary because we had already installed modules by the previous names and had not totally uninstalled them, which is a non-trivial process! So, the BigFontMaps module is rendering. The next step is to get the Google Maps API javascript registered in the page along with the BigFontMaps.js and the BigFontMaps.css. This appears to work through some Razor syntax magic. Until tomorrow, oh maps.
