SQL trigger not working for java function apps

Start with the Java function shown in the issue, host.json, and the generated extensions.csproj, then compare their configuration with the linked Azure SQL trigger tutorial and the added azure-functions-java-library-sql dependency. Reproduce the missing sqlTrigger binding and the Microsoft.Data.SqlClient platform error using the reported Core Tools and .NET versions. Done means the Java SQL trigger is discovered and its listener starts without either error.

I try to create a SQL trigger in a java function app. However I get this error:

Azure Functions Core Tools
Core Tools Version:       4.0.5413 Commit hash: N/A  (64-bit)
Function Runtime Version: 4.25.3.21264

[2023-10-23T10:55:58.376Z] No job functions found. Try making your job classes and methods public. If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(), builder.AddTimers(), etc.).
[2023-10-23T10:55:58.403Z] The 'MySQLTrigger' function is in error: The binding type(s) 'sqlTrigger' were not found in the configured extension bundle. Please ensure the type is correct and the correct version of extension bundle is configured.
For detailed output, run func with --verbose flag.

Here is my java code:

    @FunctionName("MySQLTrigger")
    public void run(
            @SQLTrigger(
                            name = "items",
                            tableName = "[dbo].[TodoItem]",
                            connectionStringSetting = "SqlConnectionString")
                    TodoItems[] items,
            final ExecutionContext context) {
        ...
    }

Here is my host.json:

{
  "version": "2.0",
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[4.*, 5.0.0)"
  }
}

I also tried removing the extension bundle and installing the sql extension directly by running this command:

func extensions install --package Microsoft.Azure.WebJobs.Extensions.Sql --version 3.0.396

which creates a file named extensions.csproj in my root folder and results in this error message:

This is the output of dotnet --info

I'd expect SQLTrigger to work as stated in this tutorial.

In addition to this tutorial I had to install the additional maven dependencies azure-functions-java-library-sql that was not mentioned in the tutorial. I have absolutely no experience working with dotnet and its runtime environment and development kits, so I might have done a mistake somewhere or missed some more steps needed.

If you need some more information on my setup, please let me know. I'm looking forward to any news on this.
