C# WPF 插入记录时出现异常 EntryPointNotFoundException

Question

I've got an WPF application I'm writing, however whilst testing the insert of a record I'm getting the below exception.

The Application is using .NET 4.8, I'm using Entity Framework 5.

The exception I'm getting is:

System.TypeInitializationException: 'The type initializer for 'ExtentPlaceholderCreator' threw an exception.'

EntryPointNotFoundException: Unable to find an entry point named 'SetClrFeatureSwitchMap' in DLL 'SqlServerSpatial110.dll'.

The stack trace is:

Looking online I can see suggestions that I need a reference in my.config file however I can only see responses for web forms or mvc rather than WPF so not really sure if its the same issue or a different one as my app.config doesn't look like the examples for those?

Answer 1

After finding an Entity Framework update I've updated, that's then advised that there was a decimal record that was out of scope so I've resolved it!
