In my current project assignment, I needed MSMQ AdapterProvider for BizTalk ESB Toolkit and as usual before implementing myself I first searched it on bing and found the link of ESB extension which contains not only MSMQ adapter provider but also others adapter providers. The ESB extension is available on codeplex for ESB 2.0. I started browing the source code of the MSMQ adapter provider and realized that due to some issue MSMQ adapter endpoint configuration are not set if we use BaseAdapterProvider implementation and as a result certain methods were re-implemented in MSMQ provider. In order to find the root cause I started writing a new adapter provider for MSMQ. I thought of documenting this here. Following are the steps you need to follow to create the adapter provider, the amount of code you write is nothing, its all implemented in BaseAdapterProvider. Its all about configuration.
- Create a new C# project and add a reference to Microsoft.Practices.ESB.Adapter assembly which you can find in Microsoft ESB ToolKit 2.1\bin folder.
- Created a new class AdapterProvider and extended it from BaseAdapterProvider. BaseAdapterProvider class is abstract implementation of IAdapterProvider interface and provides all basic functionality.
- Override property AdapterName and return adapter name from it e.g. MSMQ
- Sign and Build your project and install the assembly in GAC
- Register your new adapter provider in ESB.Config file as follows: adapterProvider name="MSMQ" type="ESB.Adapter.MSMQ.AdapterProvider, ESB.Adapter.MSMQ, Version=1.0.0.0, Culture=neutral, PublicKeyToken=8c284297668e995a" moniker="MSMQ"
- At first you think that's it and now you can see your adapter provider in your resolver under the TransportName.
- If you just need the default basic properties on your adapter provider e.g. Transport Name, Transport Location then you do not need anything else. However if you click now on Endpoint Configuration option then you get an error as shown below:
