Thank you for this answer - I didn't even think about that! – Corposant

@Kartikeya the name of my Umbraco website is not "Umbraco" - so how can i fix my issue? And how do you change the name of the MVC Project? – Luzon

This answer (and the question) still applies - for Umbraco 7.7.2. – Bonedry

Still works today on v7.7.2 Visual Studio 2017 Community with ReSharper Ultimate. Rather than renaming project i just created a new one as I was following this guide our.umbraco.org/documentation/getting-started/setup/install/… and installing from nuget. – Gaulish

Answer 2

The solution, when I encountered it after installing Umbraco 7.2.12 into an existing but empty project, was to change the assembly name and default namespace from "Umbraco" to the name of the (startup-)project eg. "Website".

In Visual Studio 2017 (applies to many other versions of VS), you can do it like this:

1. Select your project
2. Select Properties
3. Select tab Application
4. Change Assembly name and Default namespace
5. Save ... and wait
6. Run
