On the Myth of .NET Purity

On the Myth of .NET Purity

Scott Hanselman's article on "The Myth of .NET Purity" (articlenews.cfm?id=356) struck a chord (with even .NETDJ editor-in-chief Derek Ferguson jumping into the discussion).

Why the Myth Exists at All...
I think this article is right on, but felt that we should confront the issue of why this kind of rebuttal is needed (and it is needed). We find people who are earnest only in so far as they can justify their existence. Therefore they brand something heresy as soon as they abandon the practice themselves. Let's assume that COM interop was a horrible waste of resources; it still wouldn't justify discarding in such a wholesale manner a tool and the wealth of existing functionality the last generation always holds. I have heard people in ASP circles a while back declare that "session state is bad." Like hybrid applications, session state in ASP is a tool; use it or don't use it, but if you happen to need a hammer it doesn't make the saw evil.

But "Wrapping" Can Still Get Out of Hand!
I would never suggest that COM Interop should be gotten rid of or is in any way, shape, or form "evil." However, as a developer who spends more than 90% of my coding time working with the System.DirectoryServices and System.Management namespaces, let me tell you - MS could have saved developers a lot of grief by having written some managed protocol handlers here, rather than just wrapping up the old, troubled APIs.

As one example of this, the DirectoryEntry class in System.DirectoryServices allows you to pass a username and password to its constructor. However, when you use the WinNT ADSI provider, these parameters are sometimes ignored. Why is this? Because of a limitation in the existing APIs that were wrapped!

Similar problems abound in the System.Management namespace - where I recently managed to prove that Impersonation (a native API) interacts differently with EnablePrivileges (a wrapped API) under ASP.NET than it does under the Console. In working through this with MS, I have been passed around to 10 different people in their support infrastructure. Why? Because the old, obscure APIs that have been wrapped are a "dark art" known only to a few individuals within the Redmond infrastructure.

Once again: it would've been better to have recreated the whole thing in C#.

Practicality Is What Matters Most
There is a lot to be said for purity for purity's sake? I have never subscribed to this type of thinking. At the end of the day we all want to build dependable software that solves the business problem at hand. Everything should always be taken in the context of a solution with a sense of practicality. I think most of the software development community has this maturity.

Your Comments on system.directory Are Interesting
Your comments on system.directory are interesting. ADSI is simply a com wrapper, so technically it's a "wrapped wrapper" of the native LDAP API, which of course is C++ only. That being said, the directory entry class you are referring to is a "wrapped, wrapped wrapper." Ultimately, the big disappointment of the .NET Framework 1.1 and the hope for 2.0 is more native framework classes.

"We do one of the best file systems in the world. We learned how to deal with Big Data many years ago and we implemented this knowledge into our software," explained Jakub Ratajczak, Business Development Manager at MooseFS, in this SYS-CON.tv interview at 20th Cloud Expo, held June 6-8, 2017, at the Javits Center in New York City, NY.
CloudEXPO New York 2018, colocated with DXWorldEXPO New York 2018 will be held November 11-13, 2018, in New York City and will bring together Cloud Computing, FinTech and Blockchain, Digital Transformation, Big Data, Internet of Things, DevOps, AI, Machine Learning and WebRTC to one location.
DevOpsSummit New York 2018, colocated with CloudEXPO | DXWorldEXPO New York 2018 will be held November 11-13, 2018, in New York City. Digital Transformation (DX) is a major focus with the introduction of DXWorldEXPO within the program. Successful transformation requires a laser focus on being data-driven and on using all the tools available that enable transformation if they plan to survive over the long term.
Enterprise architects are increasingly adopting multi-cloud strategies as they seek to utilize existing data center assets, leverage the advantages of cloud computing and avoid cloud vendor lock-in. This requires a globally aware traffic management strategy that can monitor infrastructure health across data centers and end-user experience globally, while responding to control changes and system specification at the speed of today’s DevOps teams. In his session at 20th Cloud Expo, Josh Gray, Chie...
Containers and Kubernetes allow for code portability across on-premise VMs, bare metal, or multiple cloud provider environments. Yet, despite this portability promise, developers may include configuration and application definitions that constrain or even eliminate application portability. In this session we'll describe best practices for "configuration as code" in a Kubernetes environment. We will demonstrate how a properly constructed containerized app can be deployed to both Amazon and Azure ...
Most DevOps journeys involve several phases of maturity. Research shows that the inflection point where organizations begin to see maximum value is when they implement tight integration deploying their code to their infrastructure. Success at this level is the last barrier to at-will deployment. Storage, for instance, is more capable than where we read and write data. In his session at @DevOpsSummit at 20th Cloud Expo, Josh Atwell, a Developer Advocate for NetApp, will discuss the role and value...
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging and seamlessly coordinating both IT and developer needs for component orchestration across disparate clouds – an increasingly important requirement at today’s multi-cloud enterprise.
In his session at 20th Cloud Expo, Mike Johnston, an infrastructure engineer at Supergiant.io, discussed how to use Kubernetes to set up a SaaS infrastructure for your business.
