Exception Errors in SQL Anywhere 17 Deployment

[Former Member]

Hi everyone!

I do not know why exception errors are occurring.
I write down the condition below.
Please help me!

=========
A program built in .NET4.0 calls SQL Anywhere API.

[Windows7 Professional]
Method not found: 'IntPtr System.Runtime.InteropServices.Marshal.GetFunctionPointerForDelegate(!!0)'

[Windows8.1 Enterprise Evaluation version]
An error occurred: 'The type initializer of Sap.Data.SQLAnywhere.SAConnection threw an exception.'

[Windows10 IOT]
There is no problem.

I think that SAP are testing .NET driver on 4.5.2. Because .NET 4.5 is gone. 4.5.1 too.

https://support.microsoft.com/en-us/lifecycle/search?alpha=.NET%204.5

No reason to use old one.

Thank you for the information.

Since it is supported from .NET 4.5.2, it seems good to understand that it happens to work in .NET 4.5.1.

After that, when I investigated the execution environment, I found that there is no problem in .NET version 4.5.1 and later versions.

However, why there is no problem with .NET 4.5.1, I do not know if there is a problem with .NET 4.5.
Is there anyone who is an expert in this event?

こういうのは使っているバージョン（17.x.x)と、そのコードをコピペしないと ......

You should write product version (17.x.x) and You should write problem codes.
