Replace v1.10.3 with your installed Neos version.
Link sources to your project: To access the Debug Source Files property page, right-click on your solution in Solution Explorer and select Properties from the shortcut menu. Expand the Common Properties folder, and click the Debug Source Files page.
Add the path where you have cloned the Neos repository :

Replace c:\Projects\Neos\neos1 with your path where you have cloned the Neos repository.
