Question

Hello,
I have to implement the Point, Pointcollection, vector classes in asp.net core 5.0.
it returns me an error simply to create a pointcollection

PointCollection test = new PointCollection ();

the error returned is:
System.BadImageFormatException: Could not load file or assembly 'PresentationCore, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (0x80131058)

Hi @Marco Salvatori ,

System.BadImageFormatException: Could not load file or assembly 'PresentationCore, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (0x80131058)

Did you post this error on iis? If so, you can try the solution below:

1. Delete the PresentationCore package from the Bin folder and rebuild project.
2. There may be a problem caused by binary format compatibility, set Enable 32-bit Applications to True or False.
