Hi @Boris Sokolov use this one tutorial http://tedgustaf.com/blog/2014/4/installing-episerver-cms-75/
Hi Oleg, I don't have any idea, how this tutorial could fix the issue.
I've removed the Episerver Deplyment Center and the situation started to look better.
Also there is a big problem in the Episerver Extension - it doesn't throw you any errors during the template site creation. And if you have some local issues such as lack of permissions of other troubles - then you could get a sample site with broken or missing configs, broken DataBase and so on.
The differens is that deployment center is using local IIS and the plugin is using IIS Express.
You can try to manually create a IIS-site that points to the folder where the extension has created the site and see if that works.
By the error it seems like you have a broken applicationhost.config for your IIS Express (http://support.microsoft.com/kb/942055)
Make sure you have LocalDB for sql installed as well. The extensions use localdb for serving db.
The issue seems to be fixed for me, but it still not clear where it comes from.
Currently I have:
I have installed the EPiServer CMS Visual Studio Extension (version 7.7.0.14)
Then I've tried to create a new Episerver project: File->New->Project...->EPiServer->EPiServer Web Site. There I could choose one of three options: Empty, Alloy (MVC), Alloy (WebForms). For all these 3 types of projects I've got the same result - HTTP Error 500.19 - that points to web config. The error is the same for IIS and Visual Studio Development Server.
The Alloy site installed by EPiServer Deployment Server (ver. 7.5.394.2) works fine and it seems that it has completely different configuration
This fix http://world.episerver.com/Modules/Forum/Pages/Thread.aspx?id=80909& helps only with one issure, however the site would be still broken.
My Environment: Windows 8.1 Enterprise, Visual Studio 2012 Premium, IIS 8.5
