Add this meta layer to your project (refer to yocto user manual)

You may need to add following lines to you local.conf file (enabling access to NuGet.org in configure and compile steps):

You may not need this in local.conf it could just be in the recipe for your project in the bb recipe...

do_configure[network] = "1"
do_compile[network] = "1"

Create a new dotnet core application and include it in your yocto build as follows...

DESCRIPTION = "My dot net core 3.1 app"
LICENSE = "CLOSED"

SRC_URI = "file://hello-world.cs \
           file://hello-world.csproj \
"

inherit dotnet

This does a few things, when you inherit dotnet meta-layer class, it will does the following...

• Automatically download the host dotnet sdk for linux x64 as a native build tool dotnet-sdk-native (In the future this could become mac and windows compatible, but I only yocto on linux)
• Performs the required build steps dotnet restore and dotnet build -c Release ...

Deployment

The resultant application is a self-contained, compressed, trimmed package. No dotnet runtime is required on the target rootfs

Installation path and artifacts path can be configured from the package recipe

• INSTALL_DIR can be used to change the default /opt/dotnet/${PN} installation directory
• ENABLE_READYTORUN can be used to enable/disable AOT (default false)
• ENABLE_TRIMMING can be used to enable/disable Trimming (default true)
