Autocomplete Feature Missing

[ThunderCls]

Is it me or autocompletion is missing? I'm using v0.7.2 and nothing is shown when I try to access an entity property or function, or try to use anything like LINQ

Hello @ThunderCls. NetPad does have autocompletion and should work out of the box. When you first start NetPad it downloads then starts OmniSharp which powers a number of editor features like autocompletion, syntax highlighting, code lens...etc. If you find that these features do not work for you, can you take a look at the log files, there's a good chance the issue would be logged there. The easiest way to get to them is to open Settings (F12) and then click the "Open App Data Folder" button and check the Logs folder.

It's really weird. These logs are sticking out tho

Just to add a little bit more of context if it matters. I'm creating a new script with the following settings:

• SDK: .NET 8
• Kind: C# Program
• Optimize: Debug
• Connection: None
  I'm also on Windows 10 Pro 22H2 build 19045.2728

This seems to be a problem that occurs when upgrading to a new version while using an older version. I wanted to restore functionality right away, so I deleted the Application Data directory and ran NetPad again to confirm that IntelliSense was working normally again.

However, after changing the settings and referencing the NuGet package that I use every day, the problem occurred again. I'm also attaching the log file and App Data directory for verification.

I tested the NetPad v0.7.2 on the Apple M2 macbook Air (macOS Sonoma 14.5)

Thank you for that info, I will take a look!

@rkttu @ThunderCls can you try the new version and let me know if you're still seeing the same problem? Thank you

[rkttu]

Hmm... Since it's been a while since I ran it, I deleted the existing data directory, then replace the existing app with new app, and ran it, but it seems like the IntelliSense feature has more limitations than before. (IntelliSense for local variables is barely usable, and appears to be available only to the extent of hinting for well-known static methods like Console.WriteLine.)

I'm recording the current situation and uploading it as a video.
