Help calling SSIS package from C#

[fabjoe]

Hi all, I've written a small winForm application to call a SSIS package with a configuration file.

In addition I've added a class EventListener inherited from DefaultEvents to log execution error.

Here you are application code:

string pkgLocation;
Package pkg;
Microsoft.SqlServer.Dts.Runtime.Application app;
DTSExecResult pkgResults;
MyEventListener eventListener = new MyEventListener();
pkgLocation = txtDTX.Text;

app = new Microsoft.SqlServer.Dts.Runtime.Application();
pkg = app.LoadPackage(pkgLocation, eventListener);
pkg.ImportConfigurationFile(txtConfig.Text);
pkgResults = pkg.Execute(null, null, eventListener,null,null);

and this is MyEventListener class

public class MyEventListener : DefaultEvents
{
public override bool OnError(DtsObject source, int errorCode, string subComponent,
string description, string helpFile, int helpContext, string idofInterfaceWithError)
{
StreamWriter oFile = new StreamWriter(ConfigurationManager.AppSettings["ErrorFile"],true);
oFile.WriteLine("Error in {0}/{1} : {2}", source, subComponent, description);
oFile.Flush();
oFile.Close();
oFile.Dispose();
return false;
}
}

Running the application on a Windows Server 2008 R2 (64 bit) machine with SSIS 2012 installed (my code refers to Microsoft.SqlServer.ManagedDTS.dll version 11.0.2100.60)

the package fails and I took the following error on my EventListener: Error in Microsoft.SqlServer.Dts.Runtime.TaskHost/ : The Execute method on the task returned error code 0x80131621 (Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.). The Execute method must succeed, and indicate the result using an "out" parameter.

Can someone help me to investigate the problem?

Perhaps I need to use a different way instead of MyEventListener class?

Thank you in advance for your help.

Best regards

Fabrizio

add useLegacyV2RuntimeActivationPolicy="true" to the app.Config
