Error migrating existing 2.x addin to 3.1.x. Could not load System.Configuration.ConfigurationManager

TimothySmith6 — Tue, 10 Oct 2023 20:43:51 GMT

We are in the process of migrating our existing 2.x AddIns to 3.1.x. Several addins have migrated just fine. However we're having a problem upgrading one of them.

I've tried updating it via the Pro Migrate Project tool as well as starting a fresh Addin Project from scratch, and copying files over. Getting the same error when trying to Debug for both.

I have installed System.Configuration.ConfigurationManager via NuGet.

Error apparently being thrown from Module1 Initialize call. The error details points to FrameworkApplication.cs

System.IO.FileNotFoundException

when I look at the loaded modules for Pro 3.1 on my machine it is using version 6.0.2223 (corresponding to, i assume, the currently supported .NET version for Pro 3x - .NET 6) and not v7.

Thanks for the quick reply Charlie.

Where are you looking to see that info.

It does look like I have a 6x and a 7x version of the ConfigMgr dll.

Should I try downgrading my nuget package to 6x?

its a visual studio window accessible when u r running the debugger (see below). Sort modules on "Name".

>>Should I try downgrading my nuget package to 6x?

that sounds like it might do the trick

Charlie Macleod you are a Modern Day Hero!

That seemed to fix it. Although I'm still not sure why it was barking at me to begin with, even before I grabbed the wrong version from Nuget.

Thanks so much. Ok, on to the next disaster.....
