问题
Hi!
I'm getting a typeload exception, the assembly being loaded is targeting runtime version v2.0.50727, other assemblies targets v4.0.30319.
I've been reading about Assembly Redirection and I think it could solve this problem but I'm unsure how this would be applied in a UWP app as there is no app.config.
Any advice would be helpful!
System.TypeLoadException: 'Could not load type 'System.Net.Sockets.Socket' from assembly 'System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes'.'

In UWP platform, it would be better to create a Universal Windows Class Library then add it as a reference into the UWP project. You can try to create a Universal Windows Class Library and add your code into it as the following image,
From Windows 10 Fall Creators Update(16299), UWP supports .Net Standard 2.0, you can also create a .NET Standard 2.0 Class Library in VS2017.
Last but not least, I think you should learn more about the relationship among .Net Framework, .Net standard and UWP, you can look into the following blogs to get a better understanding:
