When I build the App in Release mode in Visual Studio it generates these files in Release folder:

App.exe 
App.dll 
App.runtimeconfig.json 
App.pdb
App.deps.json
App.runtimeconfig.dev.json

If I move the first 3 files location and double click the App.exe it starts. If I delete App.runtimeconfig.json it doesn't start!

I want to keep only App.exe and App.dll in my folder, what do I have to do to get rid of that App.runtimeconfig.json?

EDIT #1

Here's the content of App.runtimeconfig.json:

{
  "runtimeOptions": {
    "tfm": "netcoreapp3.0",
    "framework": {
      "name": "Microsoft.WindowsDesktop.App",
      "version": "3.0.0"
    }
  }
}

EDIT #2

Here's what I've now in my App.csproj file's PropertyGroup:

<PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>netcoreapp3.0</TargetFramework>
    <PublishTrimmed>true</PublishTrimmed>
    <PublishReadyToRun>true</PublishReadyToRun>
    <PublishSingleFile>true</PublishSingleFile>
    <RuntimeIdentifier>win-x64</RuntimeIdentifier>
    <UseWPF>true</UseWPF>
</PropertyGroup>

now I get this in Error List of Visual studio:

Error NETSDK1047 Assets file 'C:\Users\Emon\source\repos\SocketTest\App\obj\project.assets.json' doesn't have a target for '.NETCoreApp,Version=v3.0/win-x64'. Ensure that restore has run and that you have included 'netcoreapp3.0' in the TargetFrameworks for your project. You may also need to include 'win-x64' in your project's RuntimeIdentifiers. App C:\Program Files\dotnet\sdk\3.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets 234

When I right click on Project I see: Build, Clean, Rebuild, etc., there's no restore!

EDIT #3

I've deleted the bin and obj folders first and reordered the <PropertyGroup> to put the <RuntimeIdentifier> beneath the <TargetFramework>, now it works!

    What is the content of file? It contains runtime information and used .NET core version. You try to switch to self contained deployment Commented Nov 22, 2019 at 13:27

As you can see, App.runtimeconfig.json contains the runtime information and used .NET Core version, you can't simply delete it. But you switch to self contained deployment by selecting Self-contained deployment mode when publish the app

.NET Core introduced the ability to trim the result executable to reduce size. Basically, you need the following properties in your project file

<PublishTrimmed>true</PublishTrimmed>
<PublishReadyToRun>true</PublishReadyToRun>
<PublishSingleFile>true</PublishSingleFile>
<RuntimeIdentifier>win-x64</RuntimeIdentifier>

There is a very nice article about single executables

But RuntimeIdentifier is here:) Please, ensure that you are using it correctly and not using the RuntimeIdentifiers in plural form
Yes I missed that last time, But this time I've included that line and now I get another error. I've updated the post to show What I've done in csproj and the error
Look at this GitHub thread
Yes, now it works, I just have to have all the required dll and exe, nothing else.
For my reference, If I want a single exe, without any .dll, I've to click on Publish instead of Build, great!

I wanted to keep my csproj file as generic as possible and didn't want to specify any RuntimeIdentifiers in that file. I would rather specify the RuntimeIdentifier as a command line build option. This is what I came up with:

csproj:

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <GenerateRuntimeConfigurationFiles>false</GenerateRuntimeConfigurationFiles>
        <OutputType>Exe</OutputType>
        <Platforms>AnyCPU;x64</Platforms>
        <PublishReadyToRun>true</PublishReadyToRun>
        <PublishSingleFile>true</PublishSingleFile>
        <PublishTrimmed>true</PublishTrimmed>
        <TargetFramework>net5.0</TargetFramework>
    </PropertyGroup>
</Project>

Command line:

dotnet publish --runtime win-x64 -c Release
