[Bug]: Rider 2026.1 EAP incompatibility

[jdivy]

Description

Plugin (plugin version 1.8.2) throws an exception. I'm totally unaware of how to support Rider plugin lifecycle issues like this, just reporting what I'm seeing!

1.8.2 is a very old version. Can you try the current version of the plugin?

[jdivy]

I'm definitely out of touch with the latest plugin version, but what's interesting is the EAP thinks the current latest version is 1.8.2. I'll poke around and see if a manual installation is viable. I just uninstalled and am looking to reinstall just to double check and this is what I see:

[jdivy]

maybe EAP builds use some other kind of feed?

[belav]

Ah I bet I know what this is! I used to use an open ended compatible version, and 1.8.2 was probably the last version that was open ended. I believe now it is required to specify a version and I need to update that in the plugin each time an EAP comes out.

My computer access is limited for the next week so I may not be able to make the change until I'm back home.
