AspNet

Full source code available here. I’ve been using AutoMapper for quite a few years, but one of the features that I like the most is the ProjectTo method. When using Entity Framework it lets me reduce the number of fields I query from the database to match the model I want to return to the caller.

Full source code available here. Some time ago I wrote a post showing how to stream results from Entity Framework over Web API. This approach a few benefits – the results would not be materialized in the API code, a small amount of memory would be used irrespective of the size of the data returned, the results would being steaming as soon as possible and the speed of the request was faster than doing something like .

Full source code available here. This is an update to a post I wrote in 2017 talking about Fluent Validation in ASP.NET Core. The example is the same but there has been few updates.

Full source code here. I recently hit a problem where I needed to reload configuration settings as they changed, fortunately, this is relatively straightforward when using the IOptionsMonitor, in .NET Core.

The blog posts I have written so far about Simmy all deal with the scenario where you don’t have control over the source code that you want to break, in these cases Simmy policies are applied to the calling code.

Full source code here. A few weeks ago I wrote a post about using dependency injection to pick between two implementations of an interface. It was a solution I was not very happy with because it meant I had to new up the implementations inside a factory or I had to use service collection to instantiate all implementations of the interface and then use a piece of code to return the one the was wanted.

Full source code here. This is a simplistic approach to the problem and assumes that the dependencies created by the factory do not in turn have their own dependencies. This deficiency could be mediated by passing those dependencies into the factory.

Full source code here. There are times when you may need to access the HttpRequest from places that it is not normally available such as the constructor of a controller or the constructor of a service that is built by dependency injection.
