Sam build with project references in adjacent directory (.NET8 NativeAOT)

[kyl3t]

Hi, I have a question regarding running sam build on a .NET 8 Serverless NativeAOT project with project references referencing an adjacent directory.

My project structure is as below, building worked fine when building only the Cwoc.Lambda project but ever since including shared projects from the shared folder, the docker run command that is eventually called is not able to locate these files as they aren't mounted.

Please let me know of any workarounds or options to address this. Thanks

As mentioned by @normj in this discussion - "code-mount-directory" can be set in the aws-lambda-tools-defaults.json to reference a path that the dotnet lambda command eventually uses.
