Minification of .NET Core app

This small adventure explains how to perform minification in Windows and Linux platforms.

Windows

PS D:\work\samples\DotNetSample\MinificationTest\ConsoleApp1> dotnet publish -r win-x64 -c Release /p:PublishTrimmed=true /p:PublishSingleFile=true
Microsoft (R) Build Engine version 16.4.0+e901037fe for .NET Core

  Optimizing assemblies for size, which may change the behavior of the app. Be sure to test after publishing. See: https://aka.ms/dotnet-illink
  ConsoleApp1 -> D:\work\samples\DotNetSample\MinificationTest\ConsoleApp1\bin\Release\netcoreapp3.1\win-x64\publish\

Go to bin\Release\netcoreapp3.1\win-x64\publish\ folder
Run your app

PS D:\work\samples\DotNetSample\MinificationTest\ConsoleApp1\bin\Release\netcoreapp3.1\win-x64\publish> .\ConsoleApp1.exe
Hello World!

Now, you can just distribute the .exe for others to consume

Linux

I have WSL ubuntu 18.04 installed.

For Linux, can follow the same process with a slight change.

uadmin@MININT-BJ5SNCB:/mnt/d/work/samples/DotNetSample/MinificationTest/ConsoleApp1$ sudo dotnet publish -r linux-x64 -c Release /p:PublishTrimmed=true /p:PublishSingleFile=true
Microsoft (R) Build Engine version 16.4.0+e901037fe for .NET Core

  Restore completed in 16.62 sec for /mnt/d/work/samples/DotNetSample/MinificationTest/ConsoleApp1/ConsoleApp1.csproj.
  ConsoleApp1 -> /mnt/d/work/samples/DotNetSample/MinificationTest/ConsoleApp1/bin/Release/netcoreapp3.1/linux-x64/ConsoleApp1.dll
  Optimizing assemblies for size, which may change the behavior of the app. Be sure to test after publishing. See: https://aka.ms/dotnet-illink
  ConsoleApp1 -> /mnt/d/work/samples/DotNetSample/MinificationTest/ConsoleApp1/bin/Release/netcoreapp3.1/linux-x64/publish/

Now, go to the node and execute it. Again, this can too be distributed in other Linux machines without .NET Core installed.

uadmin@MININT-BJ5SNCB:/mnt/d/work/samples/DotNetSample/MinificationTest/ConsoleApp1/bin/Release/netcoreapp3.1/linux-x64
$ ./ConsoleApp1
Hello World!

If it is a Windows machine, you can create runnable for Linux.

Compile from Windows

PS D:\work\samples\DotNetSample\MinificationTest\ConsoleApp2> dotnet publish -r linux-x64 -c Release /p:PublishTrimmed=true /p:PublishSingleFile=true

  ConsoleApp2 -> D:\work\samples\DotNetSample\MinificationTest\ConsoleApp2\bin\Release\netcoreapp3.1\linux-x64\ConsoleApp2.dll

  ConsoleApp2 -> D:\work\samples\DotNetSample\MinificationTest\ConsoleApp2\bin\Release\netcoreapp3.1\linux-x64\publish\

Run from Linux

uadmin@MININT-BJ5SNCB:/mnt/d/work/samples/DotNetSample/MinificationTest/ConsoleApp2/bin/Release/netcoreapp3.1/linux-x64/publish
$ ./ConsoleApp2
Hello World!
