If above methods don't work, then do the below mentioned activity.

Change this line in Windows/System32/ApplicationHost.config:

<add name="ServiceModel" type="System.ServiceModel.Activation.HttpModule, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="managedHandler" />

to

<add name="ServiceModel" type="System.ServiceModel.Activation.HttpModule, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" preCondition="managedHandler,runtimeVersionv2.0" />

1. Delete whole folder of your old problematic project
2. Start VS, and you will be shown Create New Project and some links to your latest project.
3. One of the links is your old problematic project, click it!
4. Since you have deleted the folder, VS will ask to remove the link. Say YES.
5. Create your new project, now the problem is gone (hopefully).
