@Mitkari I can't reproduce your error, the command works fine. What do you mean by "in visual studio code.." ? Just open a command line, navigate to src/Photogallery and run the command. Also, make sure you have the latest .NET Core installed.

@Mitkari
You are using an old version of the NuGet's feed packages.nuget.org/v1.
Create a NuGet.config file in the project directory which contains the following:

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 
   <packageSources> 
    <!--To inherit the global NuGet package sources remove the <clear/> line below --> 
   <clear /> 
   <add key="api.nuget.org" value="https://api.nuget.org/v3/index.json" /> 
  </packageSources> 
</configuration>

Thank you so much for sharing that solution. It worked for me.
