Why isn't WCF supported in .Net Core?

28 October 2018

Development shops that have invested heavily in WCF have been left high and dry by the emerging .Net Core ecosystem. There are a number of good reasons why WCF for .Net Core is unlikely to make it onto any official roadmaps…

What makes a REST API mobile-friendly?

25 April 2018

REST API design is dependent on the clients that will be consuming the resources - APIs that are designed for server-based integrations tend to look quite different from those that are designed to support mobile applications.

GraphQL will not solve your API design problems

20 March 2018

If you find REST APIs difficult to design, develop and scale, then your experience with GraphQL is not going to be any easier.

Swagger is not WSDL for REST. It’s much less useful than that…

14 August 2017

Swagger enables the same kind of automated discovery and integration that WSDL was invented to support. In doing so it undermines the design of REST APIs and doesn’t even provide adequate documentation.

Can consumer-driven contracts manage breaking change in microservice integrations?

4 June 2017

One of the more enduring problems with service integration is managing change in service interfaces. Consumer-driven contracts can help to detect breaking changes, but this visibility comes at a price.

REST APIs don’t need a versioning strategy - they need a change strategy

The RESTafarian flame wars – common disagreements over REST API design

When developers first start using messaging they can be tempted to use it as a brand new hammer for every nail. Messaging brings a lot to the party, but it isn’t necessarily a suitable transport for fast, synchronous query processing.

Using a tolerant reader for web service integrations in .Net

22 July 2014

Using version tolerant readers can help you to cope with changes to service contracts though this does come at the expense of a weaker contract. The approach is more appropriate for fluid services that are prone to frequent change.

Hackable URIs may look nice, but they don’t have much to do with REST and HATEOAS

21 April 2014

Structured and Hackable URIs are a staple part of SEO-friendly websites. Although developers generically expect to see them in HTTP-based APIs, they should be irrelevant to consumers of a fully RESTful API that leverages HATEOAS.

Can APX help in developing usable and accessible APIs?

19 October 2013

Given how important APIs have become in driving the reach of applications and services, it’s surprising how little investment is made in the usability of APIs as opposed to UIs. Perhaps the principals and techniques used by UX should be applied to developing more effective APIs…

Netflix has abandoned OData – does the standard have a future without an ecosystem?

17 June 2013

Netflix have closed their OData catalogue and EBay seem to have quietly put their implementation out to grass. With a shrinking ecosystem and no marquee services, does Microsoft’s data standard have a future?
