I wrote a Tiny Virtual Operating System for a 300-level OS class in C# for college back in 2001 (?) and later moved it to VB.NET in 2002. This is all pre-.NET Core, and on early .NET 1.1 or 2.0 on Windows. I moved it to GitHub 5 years ago and ported it to .NET Core 2.0 at the time. At this point it was 15 years old, so it was cool to see this project running on Windows, Linux, in Docker, and on a Raspberry Pi...a machine that didn't exist when the project was originally written. NOTE: If the timeline is confusing, I had already been working in industry for years at this point but was still plugging away at my 4 year degree at night. It eventually took 11 years to complete my BS in Software Engineering. This evening, as the children slept, I wanted to see if I could run the .NET Upgrade Assistant on this now 20 year old app and get it running on .NET 6.

Interestingly, it builds on the first try, no errors. When I manually look at the .csproj I can see some weird version numbers, likely from some not-quite-baked version of .NET Core 2 I used many years ago. My spidey sense says this is wrong, and I'm assuming the upgrade assistant didn't understand it. <!-- <PackageReference Include="ILLink.Tasks" Version="0.1.4-preview-906439" /> --> <PackageReference Include="Microsoft.Extensions.Configuration" Version="2.0.0-preview2-final" /> <PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="2.0.0-preview2-final" /> <PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="2.0.0-preview2-final" /> <PackageReference Include="Microsoft.Extensions.Options.ConfigurationExtensions" Version="2.0.0-preview2-final" /> I also note a commented-out reference to ILLink.Tasks which was a preview feature in Mono's Linker to reduce the final size of apps and tree-trim them. Some of that functionality is built into .NET 6 now so I'll use that during the build and packaging process later. The reference is not needed today. I'm gonna blindly upgrade them to .NET 6 and see what happens. I could do this by just changing the numbers and seeing if it restores and builds, but I can also try dotnet outdated which remains a lovely tool in the upgrader's toolkit. This "outdated" tool is nice as it talks to NuGet and confirms that there are newer versions of certain packages. In my tests - which were just batch files at this early time - I was calling my dotnet app like this:dotnet netcoreapp2.0/TinyOSCore.dll 512 scott13.txt This will change to the modern form with just TinyOSCore.exe 512 scott13.txt with an exe and args and no ceremony. Publishing and trimming my TinyOS turns into just a 15 meg EXE. Nice considering that the .NET I need is in there with no separate install. I could turn this little synthetic OS into a microservice if I wanted to be totally extra.dotnet publish -r win-x64 --self-contained -p:PublishSingleFile=true -p:SuppressTrimAnalysisWarnings=true If I add -p:EnableCompressionInSingleFile=true Then it's even smaller. No code changes. Run all my tests, looks good. My project from university from .NET 1.1 is now .NET 6.0, cross platform, self-contained in 11 megs in a single EXE. Sweet.
