Here is a sample project which uses the same NuGet packages and has the same issue.

Hello, I recently tried to upgrade QuickOpc NuGet from version 5.63.246 to 5.70.1053, in the process I also had to upgrade the project from .NET Framework 4.7 to 4.8 in order to meet the minimum requeriment for QuickOpc (4.7.2).

I am able to run the project inside VS 2022 and run the standalone .exe but when I try to install this project as a Windows Service using 'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe', I get the following error:

The transacted install has completed.
The installation failed, and the rollback has been performed.

I have tried forcing the redirect for System.Runtime.CompilerServices.Unsafe towards 4.0.4.1 but that makes no difference at all.


Ideas? Suggestions?

Thanks.
