Re: ATEasy 2023 and .NET Core/.NET Standard Compatibility

Hello,

I created a Class Library using .NET 8. It is a simple static class, with a single static method that returns "Hello, World!".

I am able to import it into ATEasy under the .NET Assembly tab. However, when I call that function, I get the following error:

"Run-time error #420: 'Object method or property 'ThisIsATest' failed (scode=0x80004005): Unspecified error' found in 'Untitled_Test2' in line 1"

Is ATEasy compatible with .NET Core/.NET Standard?

Thank you!

Hi Kevin,

Yes, ATEasy is compatible with .NET libraries.

There is an example project, DotNet.prj, that comes with ATEasy23 you can check out.

Are you able to share the .NET library to this post?

Kevin,

Currently, ATEasy does not support .Net Core, Only .Net Standard.

.NET core will be supported in the next ATEasy version.

It looks like this is a .NET core library which is not currently supported.

Re: ATEasy 2023 and .NET Core/.NET Standard Compatibility

Hello,
I meet the same Issue. I need to import a lot of Librarys (C#.DLLs) created in VisualStudio. .NET Core is the new standard. Do the newer ATEasy version (2024/2026) supports the import of .NET Core Librarys ?

Re: ATEasy 2023 and .NET Core/.NET Standard Compatibility

Hosting both CoreCLR and .NetFramework within a single process is not officially supported by Microsoft. We will check if there is a way to do it in future ATEasy versions. If possible, we will add it to ATEasy 2027 or later this year for ATEasy 2026. ATEasy 2024/2026 currently does not support it.

Dear Ronnie, thank You for Your quick response. If possible please pickup this topic for ATEasy 2026. I thing for all other customers, who works with .dll plugins from other softwares it will be very useful.
BestRegards
Paul
