It is important if your item will be used as a key in a dictionary, or HashSet, etc – since this is used to group items into buckets (in the absence of a custom IEqualityComparer). If the hash-code for two items does not match, they may never be considered equal and Equals() will never be called. […]
When you’re testing a web service or web site with authentication credentials posted via HTTP headers, you might want a way to inject testing credentials without login in. Fiddler could help with that, but its rules need to be configured. Below I’ll describe how to do that Fiddler v4.5 (did not experiment in earlier versions).
If you notice that the context returns the same entity even if it is already changed one line before, you probably what the following
ObjectContext context = ((IObjectContextAdapter)this.Context).ObjectContext;
You can use it right after obtaining an entity with a statement like follows:
var order = this.Context.Order.Single(e => e.ID == id);
In the middle of a project you might want to automate DB restoring and upgrading by means of existing SQL scripts which may contain GO-statements. If you are that person who is attempting to execute scripts at runtime with GO-statements, this article describes how to do that.
In some cases it’s very challenging to recreate all data for some use case. It much easier to run the application, create some starting point: people, products, orders, prices, amounts, etc. and use such DB during tests. Automated tests should restore such DB in a test sandbox, run tests and drop the DB. All test frameworks have possibility to run some […]

#MSTest, #NUnit, #TDD, ...
Is xUnit is a modern and future proof solution for unit testing? I’m measuring pros and cons of xUnit and NUnit for the big and old legacy application. At the first go I thrown away MsTest because the more efforts are required to do the same things. Also it is not as extendible as others. […]
This issue is experienced while opening the test explorer or running all tests in VS. To resolve the issue try the following steps: Close all instances of Visual Studio. Delete all files in AppData\Local\Microsoft\VisualStudio\12.0\ComponentModelCache (Note that directory is located in Local.) Restart, if that doesn’t work then start over with step 4. From a Visual Studio Command […]
When an editor template is overridden with custom one you lose automatic scaffolding of client-side validation which uses data annotation rules. In such a case they should be added manually to your templates. In the beginning of HTML form you should add @Html.ValidationSummary(true). The parameter excludePropertyErrors = true because I don’t want to mix up error for […]
Several sets of goal criteria which help to make it clear and be achieved. Just a reference to remember. SMART S = Specific (context bound goal within defined scope of work) M = Measurable (easy way to estimate the progress) A = Assignable (someone shall be responsible for the goal) R = Realistic (the goal shall […]
