Re: Use of a .Net 4 assembly in ATEasy 8

Hello,

I need to use a .Net assembly in ATEasy 8 which is develop on .NET 4.
I've got this error message when I tried to use it:
Runtime error #420 : 'Object method or property 'Instance' failed : unable to load the file or assembly. This assembly was build for a most recent runtime as the runtime currently loaded and cannot be loaded.

What could be the problem? Do I need to setup something in ATEasy 8 to select the .NET 4 framework?
Thanks for your help.

Hi,

Currently, ATEasy8 only support assemblies build with target .NET framework 3.5 or earlier. We will add support for .NET framework 4.0 in the future release of ATEasy8.

To work-around this problem, you need to create an application config file containing the following XML text :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<!-- http://msdn.microsoft.com/en-us/library/w4atty68.aspx -->
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0.30319" />
<supportedRuntime version="v3.5" />
<supportedRuntime version="v3.0" />
<supportedRuntime version="v2.0.50727" />
</startup>
</configuration>

The config file must have the same name as the application (e.g ATEasy.exe.config or MyApp.exe.config) and must reside in the same folder as the application. I have created and attached to this incident a sample config file, please download, rename the file and copy it to the ATEasy folder or the folder containing your stand-alone executable.

Regards,
Albert

 ATEasy.exe.config

Hi! How about ATEasy 7? Does it support assemblies build with target .NET Framework 3.5?
