Error on generate in new project

Hi, getting this error on hitting generate in empty project, Entitas 0.47.9, Unity 2017.1.2f1

Could not find file "/..../TestEntitas/Assembly-CSharp.csproj".

In Entitas 0.42.3 it was possible to avoid this error by unchecking Update .csproj in Tools->Entitas->Preferences->PostProcessors. Unchecking this option in new Entitas versions doesn’t help

Is this error expected behaviour for new Entitas versions or a regression?

Error gets fixed by opening any .cs file in IDE which generates csproj file

Yes, that’s standard error dialog, but it could probably be improved. Maybe something like this:

Assembly file not found! Please open your project (Assets>Open C# Project) and ensure the assemblies path in Entitas preferences is set correctly. [ More Info ] [ Ok ]

And for project files:

Project file not found! Please open your project (Assets>Open C# Project) and ensure the project path in Entitas preferences is set correctly. [ More Info ] [ Ok ]

It would probably be ideal if @sschmid could make Entitas automatically open the C# project whenever you run Auto Import or Generate and Entitas detects that the project file and/or script assemblies are missing, or at least upon first run. Just showing a button to open the C# project from the error message doesn’t seem all that helpful because it doesn’t actually elaborate on the issue.

Not sure if we can actually detect project file naming issues, but adding a More Info or Help button to the error message itself, that links to the FAQ or other documentation, would be a very helpful too.

Added ValidateProjectPathPreProcessor to throw an error which will hint to the solution
