MessagePackDynamicObjectResolverException from IsolatedRuntime.Invoke

[khalidabuhakmeh]

👋 Hello,

I'm trying to recreate the Minimal API sample from your recent YouTube video (great video btw), but I seem to get a MessagePack serialization issue with the latest version of DotNetIsolator (0.1.0-preview.10032). The error details are below.

I have the following environment:

• macOS
• .NET 8.0.100-preview.4.23260.5
• DotNetIsolator 0.1.0-preview.10032
