Problem using VEnhance with .Net4.0 assembly

[Larry]

I have a class library with persistent classes using the latest release of OpenAccess.  Previously I had a script to execute VEnhance on this assembly from the command-line to facilitate automated build process.  This worked very well.  

I recently migrated to Visual Studio 2010 and switched the framework target of my persistent classes library to .Net 4.0.  Building this project within Visual Studio and allowing OpenAccess to Enhance and UpdateDatabase works just fine.  However, the command-line call to VEnhance now produces an exception.

If I switch the target framework of my persistent classes library back to v3.5 or below then the command-line call to VEnhance works perfectly.  

What can I do to get the VEnhance tool to work correctly with a v4.0 framework assembly?

Here is what I am executing at the command-line:

"c:\program files\telerik\openaccess orm\sdk\VEnhance.exe" -assembly:C:\Develop\DotNet\KSS.Data\KSS.Data.Model.WM\obj\Debug\KSS.Data.Model.WM.dll -config:C:\Develop\DotNet\KSS.Data\KSS.Data.Model.WM\App.config -debug+ -verbose+

Here are the contents of the exception:

WRN: Assembly binding logging is turned OFF.

To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.

Note: There is some performance penalty associated with assembly bind failure logging.

To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Hi Larry,
You have to tell the enhancer to run in a 4.0 vm. To do so please place a venhance.exe.config file in the same directory with this content:

<?xml version="1.0"?>
<configuration>
<startup>
  <!--<supportedRuntime version="v2.0.50727"/>-->
  <supportedRuntime version="v4.0"/>
</startup>
</configuration>

The enhancer now starts as 4.0 process and the outcome will be a 4.0 assembly.

All the best,
Jan Blessenohl

Thanks Jan! That did the trick.  I subsequently had the same issue with VSchema, but the same solution using a vschema.exe.config solved that as well.
