Cognitive-Samples-VideoFrameAnalysis | sample apps for continuous analysis | Azure library

I am trying to create a simple app that shows near real time emotions with a live web cam. I am using this guide:

https://www.microsoft.com/cognitive-services/en-us/emotion-api/documentation/emotion-api-how-to-topics/HowtoAnazlyzeVideo_Emotion

I've Downloaded the sample app: https://github.com/Microsoft/Cognitive-Samples-VideoFrameAnalysis/

but I am unsure how I could make it run. the README says: . Get API keys for the Vision APIs. 2. Open the sample in Visual Studio 2015, build and run the sample applications: - For BasicConsoleSample, the Face API key is hard-coded directly in BasicConsoleSample/Program.cs. - For LiveCameraSample, the keys should be entered into the Settings pane of the app. They will be persisted across sessions as user data.

I've got the API keys and inserted the Face API key to the Program.cs code and all of the API's into the settings.

It say's that it cannot find some namespaces as seen in the image:

Why does it say that the namespaces are not included in the Microsoft.ProjectOxford namespace ? Thanks

Edit: This was solved. After updating Nuget and all it still didn't work and the problem was that the pathname was too long. What I did was downloading the project to desktop and than pressed extract files. It created a folder with a long name and inside was another folder with a long name so the path was big. Just put it in D or just extract here and not it will extract the folder inside the zip and not create another one with the folder inside.
