Failed to load a simple project

I followed the manual page and created a simple .NET class library project.
It compiled OK. But when I click Run in Unreal Engine，some error text displayed:

LogUnrealCLR: Error: UnrealCLR::Module::Exception: Loading of assemblies failed
System.BadImageFormatException: Could not load file or assembly 'TestUnrealClrLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (0x80131058)

Unreal Engine is 4.26.2
My proj file is:

net5.0 false D:\Documents\Unreal Projects\UnrealSamples\Managed\ ..\UnrealCLR-master\UnrealCLR-master\Source\Managed\Framework\bin\Release\UnrealEngine.Framework.dll

I reinstalled the UnrealCLR the next day, and the problem is gone, do not know why...
PS:
I found why. I delete the folder "ref" auto generated by visual studio in "Manage" foler, and problem is gone.

You should publish your project to the managed folder to avoid such issues.
