target .NET framework XX for compiling DLLs (e.g., 3.5, 4.0)?

[Lord Fappington]

As the title says, what is the appropriate .NET framework for an alpha 8 compatible mod when compiling your C# DLL?

If anyone has an example they can let me look at (particularly the solution pre-assembly) would be helpful to ensure I've gotten everything right.

I'm working on the romance mod and made some progress on key features; debugged in xamarian using the associated game DLLs but when I load the mod in game screen goes black and I'm not sure how to debug it at that point .

Best,

I'm under the impression that its 3.5, at least the mod I'm currently working on works with that.

At the black screen, alt tab and go find the output_log.txt file inside the RimWorld data folder, it should help. I use JetBrains dotPeek to.. peek inside .dll files.

Hope this helps somehow.

I'm also using Xamarin/MonoDevelop and have seen the black screen when using the wrong target runtime.  3.5 is the one you want.

Thank you both EdB & Temez, indeed helpful insights!

Based on the Haplo/Mrofa tutorial I had targeted 3.5 so I had that right, thanks for the confirmation.  Therefore, thanks for the tip on the output_log.txt file to take a peak at wahts throwing the error.  My initial strategy was to deconstruct each module and load them piecemeal to see which caused the error.  Maybe the output_log can help reduce the time I go through that process.

Thanks for the decompiler tip Temeez, I've been using .NET Reflector 8 up until now.

Thank you both again for your tips!

Best,
Fap

Heres what I saw in output_log.txt, any insights?

Thanks for the decompiler tip Temeez, I've been using .NET Reflector 8 up until now.

Note that MonoDevelop/Xamarin has a built in decompiler that saves you from switching between tools.  Just double click one of the reference DLLs in your project, and it opens a class browser.  I find that it decompiles slightly better than JetBrains, but JetBrains has a couple of additional tools/features, so I occasionally use it as well.

This line "Could not find a type named WorkGiver_Romance" says that it cannot find your custom workgiver.
Is it correctly placed in the folder structure?
Correct the errors one by one as there may be a dawnfall.
