Register Component Service

After creating my simple class, I needed to set its transaction behavior.  I can do this via an attribute in my code or via Component Services MMC snap-in.

There are several options for TransactionOption enumerator, but I chose RequiresNew to create a new transaction with my component.  All available options are:

·         Disabled: This does not use a current transaction, but also will not create a new one if it is not available.

·         NotSupported: The component will be created without any control available on it.

·         Required: This uses a current transaction or creates a new one if it is not available.

·         RequiresNew: This always creates a new transaction even if a current transaction is available.

·         Supported: This uses a current transaction, but will not create a new one if it is not available.

I also set my ApplicationAccessControl for assembly attribute to true.

Listing 5

namespace AtomicTransactions
{
    [assembly: ApplicationAccessControl(true)]
    [Transaction(TransactionOption.RequiresNew)]
    public class MyTransaction  : ServicedComponent
    {

Next, I built my assembly and made it COM Visible. I also created a strong name for this assembly.  Finally, I compiled my Class Library and registered it as a Component Service via Visual Studio command prompt:

C:\AtomicTransactions\bin\Debug>regsvcs AtomicTransactions.dll
