Assets\Scripts\xxxx.cs(24,23): error CS0246: The type or namespace name 'xxxx' could not be found (are you missing a using directive or an assembly reference?)
I am able to work in play mode but the build fails The packages are installed and I checked the manifest.json and the dependencies are there
If the compiler cannot find the namespace then it surely is not there or at least not where it can be found, right? Is “xxxx” a secret? Perhaps a bit more detail would result in more people responding.
