'Metadata generation failed' when updating Microsoft.NET.Sdk.Functions to 4.1.3

[JasonAndersen7]

I am trying to update an Azure Function project from .NET Core 3.1 to .NET 6. When updating the Microsoft.NET.Sdk.Functions from 3.0.11 to 4.1.3 or later, I can no longer build the project. Instead, I get the following errors in the Error List:

• System.ArgumentException: Object of type 'Mono.Cecil.TypeReference' cannot be converted to type 'System.Type''.
• Metadata generation failed.

Similar to #585
This problem seems to be introduced by #547.

Error System.ArgumentException: Object of type 'Mono.Cecil.TypeReference' cannot be converted to type 'System.Type'.

4.1.3 or later, I can no longer build the project.

Just to confirm, If you downgrade to 4.1.2 version of Microsoft.NET.Sdk.Functions, build works?

Hello kshyju,
Thank you for responding, we were able to use version 4.0.0 and version 4.0.1 but for all other versions later than 4.0.1 the build does not work

@JasonAndersen7 I could not repro this issue. Would you be able to share a minimal repro? A GitHub repo will be great.

HI Kshyju,
I was mainly curious to see if this is a known issue or not.
Unfortunately our code is proprietary and cannot be shared
Thank you for your assistance
