  I am wondering if it is possible to replicate n number of state machine workflows from within the state initialization activity.  Thanks I don't think that solution would work, as the activity would be an InvokeWorkflow, not the child state machine workflow.  From within the workflow, you can use 'this.WorkflowInstanceId' or from an InvokedWorkflow, you can use 'invokedWorkflowActivity.InstanceId'.

     What is the best practice when running code as follows: //### code start #### SqlConnection conn = new SqlConnection("xxxx"); SqlCommand cmd = conn.CreateCommand(); //...do the necessary processing cmd.Dispose(); conn.Close(); conn.Dispose(); //### code end #### calling Dispose on the cmd and the connection seems redundant.  Additionally, if I am disposing hte connection should I first explicitly call Close()   The shortest form is simply to call conn.Close(); however even this is questionable.  conn.Close() may be valid since the connection is aware of the cmd object created with the conn.CreateCommand(), ho ...Show All

  I was wondering why LoadWithPartialName has been deprecated, anyone know If I have multiple versions of MyAssmbly.dll in the GAC for example and I want my app to load the latest version, LoadWithPartialName does the trick. What's the alternative now it's been deprecated in .NET 2.0 Very interesting point. I've just automatically thought to change the assembly version for patched assemblies, and I haven't really differentiated between file version and assembly version. I assume Windows Installer will obey file overwrite rules looking at the file version, so the assembly will actually be o ...Show All
