I have a solution where the startup project is written using .NET 8 (API). Due to legacy reasons I have to use an old project, as a helper, that is in .NET framework 4.5 (class library).
While I attempt to access a property from from the .NET framework project, I get:
Could not load file or assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=...'. The system cannot find the file specified.
Any ideas of what am I missing?
