Having trouble setting up Unity.Physics package

Hey Guys,

I just installed the physics package and am getting an error when trying to call it in a script. I am looking for some advice on how to get around it.

I am calling it with:

using Unity.Physics;

and am getting the error.

error CS0234: The type or namespace name ‘Physics’ does not exist in the namespace ‘Unity’ (are you missing an assembly reference?)

I can see the package, and that the namespace is correct. I have tried a couple fixes like reinstalling the package, re-importing all assets, some of the fixes here c# - Unity Scripts edited in Visual studio don't provide autocomplete - Stack Overflow, although I dont think that it is what my issue is as I am not seeing the “Miscellaneous Files” message.

Any advice would be much appreciated.

Thanks in advance

Just had to add the package manually to runtime.asmdef.

where is the runtime.asmdef and how do I add the package to it?
