BizTalk map renaming isn’t quite as simple as renaming the map.
I renamed a BizTalk map in VisualStudio’s Solution Explorer, compiled and deployed the application. However, in the BizTalk Management Console, the renamed map still shows up with its old name.
This is one of those BizTalk things that we’ve all been caught out by at least once.
The solution is to right-click the map name in Solution Explorer and click properties. In the properties window, change the name of the Type to the name of the map. Then redeploy.
