What version of .NET Core you are targeting? And which version of aCute do you have?

Please provide more info.

Hmm, so far I have no problems at all.

Do you have any sample project to share? If it's possible please provide minimum sample projects just to reproduce. Looking at the code in the screenshot, it looks like ASP.NET Core with minimal API code model.

Also please tell us the JDK/JRE version that is effective used by Eclipse IDE on and the version of your Eclipse IDE.

I tried using aCute and autocompletion isn't working with

ACute - C# edition in Eclipse IDE (Experimental) 0.3.3.202504111135 org.eclipse.acute.feature.feature.group Eclipse aCute

and this exception:

Do you have minimum sample code with the project setting files? I still cannot reproduce yet.

Program.cs:

// See https://aka.ms/new-console-template for more information Console.WriteLine("Hello, World!");
