Third Party PUN 2 / VS 2019 / Unity 2019.3.12f1

Good day, I am seeking some assistance. I don't know what else I can try do solve this issue.

I am using the latest PUN from the Asset Store
https://assetstore.unity.com/packages/tools/network/pun-2-free-119922

I am using Unity 2019.3.12f1
and Visual Studio 2019

When I attempt to edit any scripts VS complains that it can't find the Photon namespace. It's driving me nuts, I seem to be wasting too much time with this issue.

The type or namespace name 'Realtime' does not exist in the namespace 'Photon' (are you missing an assembly reference?) PhotonUnityNetworking.Utilities C:\Repos\SRP_Graphs\Assets\Photon\PhotonUnityNetworking\UtilityScripts\Prototyping\ConnectAndJoinRandom.cs 23


I tried
deleting all csproj, sln and .vs files/folders, restarted
deleting above plus Library folder
Removing the asset completely and reimporting.

HOWEVER, Unity itself doesn't complain and it complies correctly.

If I use Visual Studio Code it seems to not complain but I can't use VSCode due to lack of debugging and various VS2019 tools.

It seems to be something to do with VS2019? I can only assume but I can't find anyone else with the same issue. It was working just fine the day before, I re-opened it and now I have this issue.

Also.

It does see these namespaces, but only these ones.

using Photon.Pun;
using Photon.Pun.UtilityScripts;

Any suggestions would be GREATLY appreciated.

 

It seems to be the Unity Version

I went back to .11f1 and I no longer see the issue. If I use 12f1, the issue returns.

 

I'm having the same issue.

Photon Engine people don't think it is an issue with their code.

I'm also having library linking issues with unity 2019.3.12 not related to PUN, but I feel its the same issue.

It only happens in Visual Studio, unity compiles properly.

 

Maybe Visual Studio did not automaticaly load PUN assemblies in the .sln project.
Check if PUN assemblies are well displayed in the 'project' window on VS. If not, you can add them by hand.

 

Issue was acknowledge then fixed, it reappeared in unity 2019.4.5f1 LTS

 

Oh, that's new to me. Will add this to the troubleshooting page. Thanks.

 

It also reappeared in unity 2019.4.11.
I was using a photon.
but it not able to access using photon.pun. I was trying for 2 days didn't solve it.
but today I also try to solve it, in the middle of nowhere it automatically get solved.
maybe related to assembly file and vs code.
I don't know how it gets solved but before that, i deleted all library files and .csproj files. then open the script from unity multiplay time.

 

The best way to avoid this type of error is --Use Visual studio 2019

 

Me too. Switched to Visual Studio 2019 and it all works great. Autocomplete sees all the Photon namespaces. I didn't even need to bother with a project; just opened the folder. I haven't tried debugging with it yet though.

IMO can't blame either Unity or Photon, even though different versions work (i.e. distinction between a flaw and a trigger). If it compiles then the IDE should work, else the IDE is broken.

However, it would be helpful to figure out what triggered vscode to fail.
