I have the below error and have no idea how to resolve. I am attempting to setup a visual basic application under visual studio 2022 .net 8.0 which will be accessed from excel vba. Greatly appreciate any recommendations on how to resolve. MSB3217 Cannot register assembly "C:\Users\DeskTop-10\Documents\visual studio projects\MetaData_Extractor\MetaData_Extractor\bin\Debug\net8.0-windows10.0.22621.0\MetaData_Extractor.dll". Could not load file or assembly 'System.Runtime, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
Did you also try to setup an application that is based on .NET Framework instead of .NET 8?

Hello @John Smith,
Welcome to Microsoft Q&A forum.
Perhaps some settings/rules have been changed in .NET/.NET Core and this causes the assembly failed to be registered.
How did you setup it in VS 2022? Did you refer to some documents(guidance)?
Application worked with .NET Framework 4.7.2. Under .NET 8 the build only fails when Register for COM interop is selected under Compile>General. Just built new pc and upgrade to windows 11 from windows 10 and installed visual studio 2022 which replaced visual studio 2019. I believe the setup was the same. At this point I just have no idea where to even begin looking.
Check some aspects:
However, I think that it is still reasonable to use the .NET Framework instead of .NET.
Hello @John Smith,
I notice that you mentioned "when Register for COM", not very sure, but is this thread helpful: Registering Assembly fails with error unable to resolve assembly? Perhaps the setup was not the same.
Kind Regards,
Tianyu
