Self-contained apps are cool in #dotnet. You can bundle runtime and framework with the app. The downside is the size.

To resolve the size problem you can use app trimming.

.NET 5 introduces multiple options to trim the app.

1/4 🧡

#coding #devcommunity
The assembly-level trimming leaves only used assemblies in the app.

TrimMode=CopyUsed is default when using PublishTrimmed=true.

Result: 10.8 MB.

2/4
The member-level trimming is more aggressive. It removes types and members that are not used.

⚠️ It's an experimental feature. It's not ready for mainstream use.

Result: 2.58 MB.
