I'm not happy just because of installer - the version of DO bundled there is definitely better then v4.3.1, i.e. if you use v4.3.1, it's strongly recommended to upgrade.
But if you're just trying DO, this version might bring some new complexities. In this version, I migrated all our web projects to new web.config for IIS 7 / ASP.NET 4 with integrated pipeline - I thought it's a good idea, since that's what recommended. And this become a source of a set of problems:
- New web projects can be hosted only by IIS 7 - not by ASP.NET Development Server.
- You must install additional components to even open such projects in VS2010/2008.
- You must be logged in as administrator to work with such projects. I'm curious, why Microsoft doesn't fix such issues ASAP?
- And finally, impersonation doesn't work in this mode. So you should enable ASP.NET 4.0 application pool identity to login to "DO40-Tests" database on SQL Server.
P.S. Today I'll publish one more post describing the improvements we've made in v4.3.5.
