Hi all,

We have created a custom application which deploys a DDT package.  This has worked fine until the 1.7.3 upgrade.

The application does implement the ISynchronizeInvoke interface.

We are seeing that OnPreDeploymentScriptExecutionStarted gets fired off through the Invoke method (actually using a dynamicInvoke) and then a short time later Invoke is called again with an ErrorReached method.

Below is the error:

TargetParameterCountException
  Parameter count mismatch.

Any help you can give would be greatly appreciated.

Working on it, Cory. Trying to check if changes on 1.7.3 demanded new params.

Cory, there were events that get raised, but they use the ISynchronizeInvoke to see if an invocation needs to take place. Are you passing over a SyncObject on the constructor of the DatabaseMigrator? That is why I asked for your code, since looking at it we would be less confused if you weren't using a sync object, as there wouldn't be a test determining whether the _SyncObj is null. But since you say it has been working, there is mostly likely a test elsewhere.

If you can't figure this out, write a simple sample that reproduces the behavior and we will look at it.
