trouble with com.unity.ide.visualstudio package

For debugging purposes, I have enabled a breakpoint to pause the program whenever an exception of type System.Exception is thrown.

But I have a problem with com.unity.ide.visualstudio package code.
It constantly keeps throwing an exception of type NullReferenceException, on line 63, inside OnIncomingConnection.

I'm not sure what is the purpose of that method. But it comes in the way of debugging and breaks the debug flow all the times.
I ended up adding this piece of code to the global cache, to prevent this from happening.
I'm not sure how I can contribute to the actual project, but I hope some maintainer sees this and fixes this in the actual package.

Code (CSharp):

1.                 if(state.TcpListener == null)
2.                     return;

Thanks!

 

Seems this doesn't totally fix the problem. I can still get this exception, to interrupt my debugging session:

Message "Cannot access a disposed object.\nObject name: \'System.Net.Sockets.Socket\'." string

"System.ObjectDisposedException: Cannot access a disposed object.\nObject name: \'System.Net.Sockets.Socket\'.\n at System.Net.Sockets.Socket.ThrowIfDisposedAndClosed () [0x0001b] in <aa976c2104104b7ca9e1785715722c9d>:0 \n at System.Net.Sockets.Socket.EndAccept (System.Byte[]& buffer, System.Int32& bytesTransferred, System.IAsyncResult asyncResult) [0x00000] in <aa976c2104104b7ca9e1785715722c9d>:0 \n at System.Net.Sockets.Socket.EndAccept (System.IAsyncResult asyncResult) [0x00000] in <aa976c2104104b7ca9e1785715722c9d>:0 \n at System.Net.Sockets.TcpListener.EndAcceptTcpClient (System.IAsyncResult asyncResult) [0x00034] in <aa976c2104104b7ca9e1785715722c9d>:0 \n at Microsoft.Unity.VisualStudio.Editor.Messaging.TcpListener.OnIncomingConnection (System.IAsyncResult result) [0x0001d] in /Users/p/Desktop/Source/Library/PackageCache/com.unity.ide.visualstudio@2.0.9/Editor/Messaging/TcpListener.cs:63 "

 

Can I in any way instruct Visual Studio to ignore this file, from the general System.Exception exception breakpoint?

 

Hi,

Same issue here except NullReferenceException is still raised inside OnIncomingConnection but line 60 instead of 63 (package version is not the same).

I'm not sure it's relevant, but I use the Test Framework a lot and so far, the issue occurs only when I run the tests. Also, the tests are located in an embeded package not in the Asset folder.

Versions of everything are :
Unity : 2021.1.15f1
VisualStudio Community 2019 : 16.6.2
com.unity.ide.visualstudio : 2.0.11
com.unity.test-framework : 1.1.27

 

Same issue. Does anyone know if this has been fixed? It's extremely annoying when trying to debug anything.

 

I had to update the package, and here we go again. Need to patch the global cache of the newer version of the package again. I wish I knew who could help us with this issue from Unity, so I could mention the person.

 

How do I modify the C# file from the package (or the global cache)? Unity (or Visual Studio?) will revert every change I make to the TcpListener.cs script.

 

What platform are you on?

 

I'm on Mac OSX (Monterey) / Unity 2021.2 / VS 2019 Community

 

Thanks! That looks promising. Would you mind moving the thread there?

 

Global Cache locations: https://docs.unity3d.com/2019.3/Documentation/Manual/upm-cache.html

For your platform you can find the file in this location:
$HOME/Library/Unity/cache/packages/packages.unity.com/com.unity.ide.visualstudio@2.0.12/Editor/Messaging/TcpListener.cs

(make sure you are using the folder with the right package version)

 

Do you know who can help fix this issue from Unity?
this problem still exists even in version 2.0.16 and it's annoying having to include that code after every update.

 

And then no one solves this issue:

System.NullReferenceException: Object reference not set to an instance of an object
at Microsoft.Unity.VisualStudio.Editor.Messaging.TcpListener.OnIncomingConnection (System.IAsyncResult result) [0x0000e] in D:\MyProject\Library\PackageCache\com.unity.ide.visualstudio@2.0.17\Editor\Messaging\TcpListener.cs:60

 

I just started getting this while debugging tests, maybe something short lived.
com.unity.ide.visualstudio@2.0.22
