Socket error while session is still alive

[rstm-sf]

Hello!

When a plugin sends a message via avalonia-remote that the server cannot parse, an error occurs that is not shown in the preview

@TheForgetTime hello, can you tell what actions preceded this?

@TheForgetTime hello, can you tell what actions preceded this?

compile the project and double click on the xaml file

Hi @ForNeVeR

I see the same issue in Rider. I think it is not a big deal as everything compiles as expected. If you need any information from my side I would be glad to help.

By the way: Thank you for the great plugin 👍

Hello! Today I have the same error after switching solution to other in current window. Idk will it affects stability / crashes or not, but my IDE is still working properly, and the preview works fine too. I'm using Rider 2021.3.2 build RD-213.6461.51, my operation system is Windows 10, AvaloniaUI framework version is 0.10.11 bleeding edge. The AvaloniaRider plugin version is latest from marketplace (1.0.0.1540867288, installed on 25.01.2022)

[JosephFerano]

Getting a similar error. All I did was install the plugin and I tried to launch the preview from the Full FuncUI project template.

[kroltan]

I get the same error, but for me the XAML preview doesn't work (although it did previously)

Rider 2022.1.2 (Build #RD-221.5787.36) AvaloniaRider 1.0.0.2140933515 Avalonia 0.10.18 Avalonia.ReactiveUI 0.10.18 On an up-to-date Linux Manjaro 21.3

Vaguely different line numbers from @JosephFerano, but otherwise looks the same.

[ForNeVeR]

And what does the previewer log say?

[kroltan]

I don't know where to view that, could you clarify?

[ForNeVeR]

Just open the Avalonia tool window, it will show the logs.

[kroltan]

Oh right, I didn't know about that window.

Turns out it was an issue in my application code, not the plugin's fault. I assumed that because my application is being developed only for desktops, that meant that the ApplicationLifetime would have always been IClassicDesktopStyleApplicationLifetime, but apparently a different lifetime is used for design-time, so it was crashing. I fixed that and rebuilt the project and now the previews work fine!

Sorry for the noise.

[ForNeVeR]

This is alright, and the discoverability of a said output window is still an unresolved problem within the plugin.

Getting this on latest Rider as well:

If this is caused by an exception in my code, it would be great to see the stacktrace down to that exception in order to get some hint of what could go wrong.
