Trim in publishing

[taooceros]

Question
Why don't we trim in publishing profile? In dotnet 5 environment, although it takes time to do the job, it can reduce the output size from 92MB to about 58MB

That would be good to trim down the size, I just haven't had time to look into it

Trimming is still experimental afaik.

Also, curiously, self-contained net5.0-windows output is actually larger than the netcoreapp3.1 equivalent: 84mb vs 78mb for the executable...

Maybe that is because of the large WinRT runtime. Around 26mb.

hmmm seems that trimming break Flow to work as intended. Need more testing.

A couple more suggestions to try, leaving it here for future reference:

Had some trouble.
A version that does exist does work sort of. Control panel plugin does not work, and portable mode is a ??

Maybe plugin shouldn't be trimmed. By the way, you may need the self-contained=true as well for testing this.
Try take a look on the post_build.ps1, and builds other projects with release, and publish only the Flow.Launcher project.

[XavBryant]

I dont know how to use that file.

[taooceros]

hmm just try only publish the Flow.Launcher project, and build other project before it. Don't publish everything as self-contained. Sorry, I got something to do now, so unable to help you until later.

Working publish build is at 80mb after stripping plugins. Half the size of the original.
Cant recreate however.

--update1. Exported all of my current settings over, and the application seems completely stable. Final size compared to my older version: 74.51mb [this includes deleting all plugins except plugin manager, shell, and calculator]

--update2: still trying to recreate this build.

i forgot to include true for both the build and publish.

[XavBryant]

Resolved.

Install https://github.com/dotnet/standard/blob/release/2.0.0/Microsoft.Packaging.Tools.Trimming
add true onto 5.0SelfContained.pubxml

seems to work fine.
from 293mb to 127mb, mileage may vary but no issues encountered so far.

Looks quite promising. You can open a pull request for that😲
