Disable nunit since it conflicts with System.Collections.Concurrent

Hi.
We have upgraded to 5.6 and now get compile errors. We use the Concurrent collections in System.Threading, the ConcurrentQueue is also defined in nunit.framework so the code does not compile.

 

I reported a bug on this, it seems like a bug that nunit.framework define types with same strongly typed name as System.Threading

 

I'm running into this issues as well.

Report Case 897850

Anybody know if there are work arounds to this problem>

 

We have the same issue.

 

Same issue here. Could not find a workaround that is reasonable.

 

To clear up, the problem isn't that NUnit has it's own ConcurrentQueue. It's that NUnit seems to drag along it's own version of System.Collections.Concurrent.

Which means that this code won't compile:

Code (csharp):

1. public class Foo {
2.     public void Bar() {
3.         System.Collections.Concurrent.ConcurrentQueue<string> queue;
4.     }
5. }

Which is an incredibly breaking bug. I think Unity automatically adds nunit as a dependency to projects these days. If you open the project in Visual Studio or something similar, and delete the nunit dependency, the code compiles in VS, but Unity dutifully ensures that the dependency's always there.

The only possible work around is to wait for a patch or roll back to 5.5. Or create your own version of a concurrent queue?
Edit: Looking into this further, it seems like the System.Collections.Concurrent exists in 5.5(1f1), so this is probably not a breaking change.

 

We are on 5.5.3 and do not get the conflict

 

We want to test out Vulkan and the new lighting mode so I hope Unity sorts out this fast. Our netcode is heavily dependent on the different concurrent classes in the System.Threading assembly

 

Another factor for us is that we use the Gamesparks API which also defines System.Collections.Concurrent

 

It would be better if Unity used their own namespace for this class so it does not conflict for us that import the Actual .NET assembly

 

Just to be clear we use the 3.5 version of System.Threading assembly

 

Thanks i can now compile, but I get GL.End requires material.SetPass before! when the game starts

 

I still get errors in VS2017 btw, but it seems to compile from within Unity

 

Bumping this thread. Has anyone found a work around?

 

Works in 2017.1

 

Hi,
I'm getting the same problem in 2018.1.3 when I use the .NET 4 Equivalent Scripting Runtime Version and replacing the nunit files doesn't seem to fix it. Any help would be appreciated.
