Why the exe file of a new .net core console application is so big?

I created a new .NET Core 3.1 console application, and did not modify the code (so it is only a hello world example).

I published the application into a folder with the following settings:

<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <Configuration>Release</Configuration>
    <Platform>Any CPU</Platform>
    <PublishDir>bin\Release\netcoreapp3.1\publish\</PublishDir>
    <PublishProtocol>FileSystem</PublishProtocol>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <SelfContained>false</SelfContained>
  </PropertyGroup>
</Project>

After publishing, it created 5 files. The two interesting ones:

• TestApp.dll - 4608 bytes
• TestApp.exe - 174 592 bytes

(Others are insignificant now: pdb, deps.json, runtimeconfig.json)

As I learned, the DLL file contains all my source code (I checked it with ILSpy as well). But why is the exe file so large? As far as I know, it should be just a wrapper that calls into the framework with the DLL file as entry point.

How can I reduce its size?

I want to make a simple utility application but it seems like the minimum size is 200 KB? That is absurd.
