Could not load file or assembly "Newtonsoft.Json" about functionmonkey

[fpyir]

I have narrowed it down a bit - the error seems to appear if I use JsonProperty on an ICommand-implementing class (in my case, AddTenantToPolicyCommand.cs) as followed:

using AzureFromTheTrenches.Commanding.Abstractions;
using ICE.Models;
using Newtonsoft.Json;

namespace ICE.Commands.Policies
{
    public class AddTenantToPolicyCommand : ICommand<Policy>
    {
        [JsonProperty("name")] // Commenting this out stops the error.
        public string PolicyName { get; set; }
        
        // [JsonProperty("newTenant")]
        public int NewTenant { get; set; }
    }
}

I have a sneaking suspicion that this has something to do with the way JSON serialisation & deserialisation is done natively by FM?

Or, if a command subclasses from a class with JsonProperties.

Thanks for reporting it and doing all that digging around - I'll try and take a look today (I'm on UK time).

[JamesRandall]

Apologies - struggled to find any time the last couple of days but almost certainly will over the weekend.

Could you give this a go on the latest Azure Functions runtime with Function Monkey v0.13 please and let me know how you get on?

I'm struggling to replicate it but my attempts to do so have taken place after updating Function Monkey to be compatible with the new runtime.

[fpyir]

Yep will do - currently doing some spring cleaning on the codebase but I should get around to this in 3-4hrs.

I can, in fact, confirm this isn't happening anymore. Weird, perhaps due to the new AZ function runtime?

[JamesRandall]

Yes I think so - I'd suspected it might be. They've done a lot of work around the dependency compatibility issues caused by things being in process and packages in the core runtime in the last couple of releases and the last update made the final set of changes for v2. It was super easy to get into a pickle before.

Phew.

Thanks for reporting and working through with me, much appreciated.

Hi James,
This seems to have reared its head again. Using FM 3.0.17 with Microsoft.NET.sdk.Functions 1.0.30-beta2 results in :
