How to skip the mapping between properties of a source and a target object in AutoMapper

As I did in my previous article, I focus again on the AutoMapper framework.

When I map one object to another, I often deal with a destination object that contains LESS properties than the source object. If I take no action, an exception is going to be thrown. For that we will have to declare the skipped properties by using the DoNotValidate method when we define the mapping (CreateMap) between the two objects:

Use a custom function when mapping one property to another with Automapper

Automapper is a handful tool for mapping the properties of two different type objects together. Such mappings are very common when you are dealing with a multi-tier architecture in your program.

A possible reason for the .NET MVC "The view XXXX or its master was not found" error

“The view XXXX or its master was not found” error looks like that:

~/Views/Shared/XXXX.cshtml
~/Views/Shared/XXXX.vbhtml"

Run your Load Tests against multiple server environments, like localhost, development or integration

Load Tests help us identify bottlenecks in our application and can answer with high precision how many users our infrastructure can support in a given time. In a previous article I gave you some tips for using the Load Tests from Visual Studio in a more efficient way.

Today I would like to show you how you can run the same load tests against different server environments, for example on your localhost machine and on the integration server, before deploying a change into the production.
