ESB Toolkit overrides BizTalk config (BTSNTSvc.exe.config)

I’ve setup a BizTalk Server 2013 environment with ESB Toolkit 2.2 and since I use Enterprise Library for logging I also updated the BTSNTSvc64.exe.config file, but when I tried to run a sample application it throws an error:

Activation error occured while trying to get instance of type LogWriter, key “”:Microsoft.Practices.ServiceLocation.ActivationException: Activation error occured while trying to get instance of type LogWriter, key “” —> Microsoft.Practices.Unity.ResolutionFailedException: Resolution of the dependency failed, type = “Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter”, name = “(none)”.

Exception occurred while: while resolving.

Exception is: InvalidOperationException – The type LogWriter cannot be constructed. You must configure the container to supply this value.

Apparently, ESBToolkit is overriding the BizTalk configuration.

Solution:

Move the configuration to \esb.config file.

C# Enterprise Library Asynchronous Logging

We all know how slow any logging mechanism is, specially when one of the trace listeners is logging to a database. By using .NET 4.0 with it’s Parallel Library (System.Threading.Task) we can easily turn our logger to use fire-forget asynchronous operation.

 Example below uses Enterprise Library 5.0.

Suppose this is your existing LogMessage method:

Just add another method LogMessageAsync with ff code:

Now to log asynchronously just call the LogMessageAsync() method.
