When cloud-based applications use other cloud-based services, errors can occur because of temporary conditions such as intermittent service, infrastructure-level faults, or network issues. Very often, if you retry the operation a short time later (maybe only a few milliseconds later) the operation may succeed
When a client sends data to your web API, often you want to validate the data before doing any processing. This article shows how to annotate your models, use the annotations for data validation, and handle validation errors in your web API.
This article takes a comprehensive look at the business of generating and sending email from an ASP.NET MVC application. It covers the most common use cases as well as some advanced scenarios. It also explores some of the more common errors that arise from attempting to generate and send email programmatically from an ASP.NET MVC site.
The most important thing I learn in 2015 is that clean code is everything. You can have bad performance or logical errors or even security issues.
But without clean code you cannot fix anything above, because you don't understand the code.
