I just downloaded v3 of SharpDevelop but I can't seem to locate the database explorer.
The comparison of v2.1 to Visual Studio Express says that a Database Explorer is built in
If it is in 2.1, why isn't it in 3.0??
This blog also seems to imply some sort of support
I have also seen references to Addins called ServerTools and SharpQuery that would provide support, but I can't find either anywhere.
