Hi Experts,
 
I am getting a below compilation error.
 
Severity    Code    Description    Project    File    Line    Suppression State
Error        Type 'System.Runtime.CompilerServices.NullableContextAttribute' not found in assembly 
'System.Runtime, Version=4.1.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' 
Please run a full compilation of the model corresponding to the assembly 'System.Runtime, Version=4.1.2.0, 
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
 
I have a DLL from C# Library project and referenced the DLL in for my X++ customization. While compiling I getting the above error.
 
Target framework of C# Library project is .NET 8.0 (I also tried generating DLL with .NET 6.0)
 
Any guidance please.
 
Regards,
Sridhar

    I'm assuming this is about F&O, not AX. Please confirm that and I'll move this thread to the Finance  forum. 
      
    Your target framework is indeed wrong. You must  build the assemble for .NET Framework, not .NET Core, namely .NET Framework 4.7.2.
