bin/content.server/content.server.dll After Building C# Project in Robust Toolbox

I’m working on a C# project using the Robust Toolbox engine, as documented here: https://docs.spacestation14.com/. However, after following the guide, I’m encountering an issue where the bin/content.server/content.server.dll file is missing after building the project.

I’ve tried the following steps multiple times:

dotnet clean
dotnet restore
dotnet build

Despite repeating these steps, the content.server.dll file is still not being generated.

Can anyone point out what might be going wrong or suggest further steps to resolve this issue?

Here’s a screenshot of the project structure:

Any help would be greatly appreciated!
