Hi,
If I open the file StoreDayHoursManager.cs in visual studio from the Proxies.RetailProxy.Extensions.StoreHoursSample.csproj project:

In an untouched RetailSDK I will get an error:

I get the error because the IStoreDayHoursManager interface is declared in another auto generated file (interfaces.g.cs) that is not included in the project:

But when I build the project, everything is fine:

Is there a switch or something on the project that ignores this compilation error?
The reason I'm asking is because I have a proxy extension of my own with the exact same error but it won't compile:
