[Rider] Devserver connection fails

Open jeromelaban opened this issue 1 month ago • 5 comments

From https://github.com/unoplatform/uno/issues/22012#issuecomment-3603431064 by @codymullins:

I upgraded to .NET 10 and it works.

Observation: dev server fails to connect, and presumably, this hides the executable window and pops rider back open. I remember this happening before and found it quite annoying. It seems to happen mostly every time. I caught it on recording where it happens the 2nd time.

@codymullins could you provide the output of the Uno Platform tab? It will help troubleshooting.

jeromelaban avatar Dec 02 '25 18:12 jeromelaban

Do you mean the terminal output? If not, please correct me and I'm happy to share.

Thanks. I meant in the IDE, there's should be an Uno platform logo on the left side of the IDE, but it's not there, which would explain the issues when connecting to the dev server.

I wonder, have you installed the uno platform extension? This could also explain the issue with the .NET 10 vs 9 issue.

I see the same experience with the Uno platform extension enabled. I uninstalled/reinstalled. Here are the logs.

I still get this whenever I run the Uno app. Let me know if you need any further information from me.

codymullins avatar Dec 09 '25 19:12 codymullins

Probably not linked to your case because in your log you have Dev server is started with port 52228., but worth mentioning here.

I just found a bug that will cause the bug reported here: if in the <MyProject>.csproj.user the value of the <UnoRemoteControlPort> node is 0 (which might be the case when you open the solution with multiple different IDEs), this will cause the Dev Server to fail to start.

You can see that in the "Uno Platform Status" pane (cf. https://aka.platform.uno/uno-platform-status)

Image

Also in the logs you will get Dev server is started with port 0..

WORKAROUND

Simply change the value to a random number (lower than 65535 !), e.g.

<UnoRemoteControlPort>12345</UnoRemoteControlPort>

(internal issue: https://github.com/unoplatform/uno.rider/issues/438)
