NetCoreBeauty

What is it?

NetCoreBeauty moves .NET Core app runtime components and dependencies into a sub-directory to make it beautiful.

After Beauty

Before Beauty

Why And Why Not?

WHY NOT Single-file Publishing?

First, you cannot use it in .Net Core 2.x, obviously. Second, single-file app publishing will extract everything into a temporary directory and run it from that location. For that reason, a portable app is impossible if you are using Assembly.GetEntryAssembly().Location to store persistent data. This is not an issue with Beauty, but netcore single-file publishing.
WHY NOT Fody/Costura?

Fody/Costura is fantastic project, but there are some reasons why you might not want to use it. First, it modifies IL code which will have possibly unpredictable effects. Second, you need to make assemblies become embedded resources, which is extra work, and in some cases, may cause issues. I encountered this issue, and it was difficult to find the culprit. Third, it adds a layer of complication to a project, more points of failure, and without knowing exactly what the tool is changing, a developer can't easily fix the errors.
WHY NOT Warp?

Like Single-file Publish, it does not extract data into the current directory. It extracts into %APPDATA%, so a portable app is still impossible. In addition, Warp cannot set the icon or assembly information, and it won't use the information from the original app after extraction.
WHY NOT ILMerge?

It merges multiple assemblies into a single assembly. It needs to modify your assemblies, adding possible namespace or reflection errors. You can still can re-sign all your assemblies to use strong names, though. It's also Windows only
WHY NOT AppHostPatcher?

AppHostPatcher has a similar goal as ncbeauty, but has a little problem. Data is stored inside APP_BASE/sub-dir, not APP_BASE directly. That is because apphost's main assembly has been moved into APP_BASE/sub-dir, and the actual APP_BASE has changed to APP_BASE/sub-dir. Like the other projects, it can possibly cause unexpected behavior.
WHY NetCoreBeauty?

NCBeauty has a single and simple goal. It does nothing to your project and assemblies. It only organizes your app's directory, so you need to do nothing but reference the NuGet package.

How?

Theoretically, loading assemblies from a subdirectory should be natively supported (see additionalProbingPaths setting under runtimeOptions), but setting additionalProbingPaths in .runtimeconfig.json has a serious problem. The host does not resolve the relative path from APP_BASE, but the current working directory, therefore, we cannot execute the app outside of APP_BASE. This means that the only way to run the app is via a terminal with cd APP_BASE & ./executable. Running from the file explorer would fail. HostFXRPatcher fixes this problem by rebuilding the corehost. When publishing, ncbeauty will try to download the specific patched hostfxr and modify .runtimeconfig.json and .deps.json. That is why ncbeauty only works with self-contained deployments mode. Why not PR? Because this fix breaks lots of things, so a merge is not going to happen in a short time. .NET community already plan to fix in .NET 5.

How to use?

Add Nuget reference into your .NET Core project.

dotnet add package nulastudio.NetCoreBeauty

Your *.csproj should be similar to this

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <!-- beauty into sub-directory, default is libs, quote with "" if contains space  -->
    <BeautyLibsDir>libraries</BeautyLibsDir>
    <!-- dlls that you don't want to be moved or can not be moved -->
    <!-- <BeautyExcludes>dll1.dll;lib*;...</BeautyExcludes> -->
    <!-- set to True if you want to disable -->
    <DisableBeauty>False</DisableBeauty>
    <ForceBeauty>False</ForceBeauty>
    <!-- <BeautyAfterTasks></BeautyAfterTasks> -->
    <!-- set to True if you want to disable -->
    <DisablePatch>False</DisablePatch>
    <!-- valid values: Error|Detail|Info -->
    <BeautyLogLevel>Error</BeautyLogLevel>
    <!-- set to a repo mirror if you have troble in connecting github -->
    <!-- <GitCDN>https://gitee.com/liesauer/HostFXRPatcher</GitCDN> -->
    <!-- <GitTree>master</GitTree> -->
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="nulastudio.NetCoreBeauty" />
  </ItemGroup>

</Project>

When you run dotnet publish -r (only works with SCD mode), everything is done automatically.

Use the binary application if your project has already been published.

Usage:
ncbeauty [--force=(True|False)] [--gitcdn=<gitcdn>] [--gittree=<gittree>] [--loglevel=(Error|Detail|Info)] [--nopatch=(True|False)] <beautyDir> [<libsDir> [<excludes>]]

Setting GitCDN:
ncbeauty [--loglevel=(Error|Detail|Info)] setcdn <gitcdn>
ncbeauty [--loglevel=(Error|Detail|Info)] getcdn
ncbeauty [--loglevel=(Error|Detail|Info)] delcdn

for example

ncbeauty /path/to/publishDir libraries "dll1.dll;lib*;..."

Install as a .NETCore Global Tool

dotnet tool install --global nulastudio.ncbeauty

then use it just like binary distribution.

Mirror

If you have trouble connecting to github, use this mirror

Default Git CDN

ncbeauty 1.2.1 supports setting default Git CDN now, so you don't need to --gitcdn all the time if you are using the binary distribution. The default git cdn can still be overriden with --gitcdn. Usage:

ncbeauty [--loglevel=(Error|Detail|Info)] setcdn <gitcdn>
  set current default git cdn, can be override by --gitcdn.
ncbeauty [--loglevel=(Error|Detail|Info)] getcdn
  print current default git cdn.
ncbeauty [--loglevel=(Error|Detail|Info)] delcdn
  remove current default git cdn, after removed, use --gitcdn to specify.

Git Tree

Use --gittree to specify a valid git branch or any git commit hash (up to 40) to grab the specific artifacts and you won't get updates any more. The default always uses the latest artifacts.

NOTE: please provide as long of a commit hash as you can, otherwise it may can not be determined as a valid unique commit hash.

NOTE: PLEASE DO NOT USE ANY COMMIT THAT OLDER THEN 995a9774a75975510b352c1935e232c9e2d5b190
