Roslyn: How to get all projects from a solution (old vs. sdk style csproj) #994

Closed sschmid closed 2 years ago

Hi!

I'm having an Roslyn issue, sounds simple, but can't get it to work:

Task:

get all projects in a solution and iterate over their documents

Problem:

sdk-style csproj have no documents, only the old-style csproj

I created a test repo to test this in isolation https://github.com/sschmid/RoslynTest

This will be very useful for the Entitas code generator.

Does anyone how to fix this?

I don't know how exactly this is solved, but I know that Genesis has solved it. This is the directory you'll want, I think. Does that help?

Yeah, he's using MSBuildLocator.RegisterDefaults() from Microsoft.Build.Locator. Unfortunately:

Operation is not supported on this platform

Only works on Windows

I'm using mono-hosted-msbuild https://github.com/dotnet/msbuild/releases/mono-hosted-msbuild-v0.03

to be able to run roslyn on macOS and linux

sschmid commented 2 years ago

But I was about to try that with GitHub actions on a windows hosted machine. Let's see if that works

Hey @jeffcampbellmakesgames, what do you think?

sschmid commented 2 years ago

Solved.

Entitas and Desperate devs was .NET 4.x to be compatible with Unity.

Jenny however can be net5.0 or newer. Using net6.0 fixes it 😍

I believe this might have been the case for the .Net Framework version, but on .Net Core 3 this was not the case (supports Windows, macOS, and Linux). That is why Genesis works on all three platforms as a portable app.

Going with latest .Net Core is definitely the way to go! I've seen some issues on macOS on Silicon machines where the .Net 3 SDK can be installed, but not the runtime (which may or may not be by design depending on some Github issues I'd seen). It's one of the reasons I'll be updating to .Net 6 in the near future as well (along with the bevy of other awesome perf benefits and other handy features).
