Getting a Runtime Error trying to Load DLL with dotNet API

[diepreyeYRJFU]

Hey,

I am having issues trying to use my C# code in Maxscript. I just wrote a test cs code and Maxscript to test the two's functionality. The code isn't anything complex at all but I keep getting the following output and error:

dotNetObject:System.Reflection.RuntimeAssembly
-- Error occurred in anonymous codeblock; filename: C:\Users\diepreye\Desktop\.net 3ds max plugin prac\dotnet_api_test.ms; position: 117; line: 3
-- Runtime error: Cannot resolve type: Sandbox.TestObject
-- MAXScript callstack:
-- thread data: threadID:22972
-- ------------------------------------------------------
-- [stack level: 0]
-- In top-level

I have also attached a copy of the C# code and the Maxscript code below. I have no idea why it isn't working especially since I search and see others doing the same and having no issues.

Have you installed the latest dotNET update for Windows?

Yes I have .NET 8.0 installed

Alright, I have seen the issue. It seems 3ds Max doesn't like/fully support .NET 8.0 SDK yet. I retried writing my plugins and test code using the .NET 4.8 Framework which works perfectly.
