Nothing works

[MdmrBerlin]

Whitch status have this project?

Ready for use, alpha or beta?

I tryed the readme steps, downloadet the CodeGeneration.Roslyn.Walkthrough and another example.
There is actual no way to compile the projects or generate code, also the the example projects.
Maybe your documentation and example projects are out of date?

Hello, can you provide a little more context, e.g. what version of Visual Studio are you using?

I've updated the walkthrough (see PR: jaredthirsk/CodeGeneration.Roslyn.Walkthrough#2) for 0.4.88 and it does work for me under VS2017 v15.9.5 (latest).

[jaredthirsk]

I haven't looked at this in a while. I merged the PR but maybe I shouldn't have -- I can't get it to work. It looks like dotnet codegen is missing? 0.4.11 had DLL code in nuget: ~.nuget\packages\codgeneration.roslyn.buildtime\0.4.11\build\net45 and ...\netstandard1.5, but under 0.4.88\build, these folders don't even exist!?

Here is my log to attempt to rebuild:

Update: I got the https://github.com/jaredthirsk/CodeGeneration.Roslyn.Walkthrough solution compiling. I remember I had uninstalled a VS2017 preview recently, and noticed I didn't have .NET Core 2.0 SDK installed (it is past end of life -- I have several newer SDKs installed, including 2.1, 2.2, 3.0-preview). I went to install it and it thought it was already installed, so I did a repair. Now the Walkthrough builds in VS 2019 preview, and VS 2017. So there could have been something broken on my machine, or perhaps 2.0 SDK is needed (if so, that should probably be changed because it is past EOL).

[amis92]

Yes, it's true that the experience (when no SDK 2.0) is bad. There's the thing called prefercliruntime but it's undocumented and I do not know if this'll work or what it does :)

[jaredthirsk]

Can you just easily upgrade this repo to depend upon a newer (non-EOL / non-obsolete) SDK?

[amis92]

(I'm not the owner of CG.R) Well, the thing is that we'd need to upgrade the tool for each new SDK version, which is just bad. Probably using prefercliruntime we'd "declare" ourselves compatible with the running/available SDK so that we could work for more targets. :<

[AArnott]

Thanks, @amis92. I have no objection to targeting a newer .NET Core if someone can send a PR to update that (and @amis92's new documentation to match 😄).
