NUnit V2 2.6.0b2

General

    * NUnit's executables now use config files that allow smoother running of mixed assemblies built for .NET 2.0 under .NET 4.0.
    * When opening Visual Studio formatted solutions, NUnit now uses the solution configuration by default, resulting in changed behavior from previous releases. The Settings Dialog may be used to revert NUnit to the earlier behavior, which ignored solution configurations.
    * Changing the URL to be used for NUnit help through the config file is no longer supported.

Framework

    * TestCaseAttribute now accepts Explicit and Reason named parameters.
    * TestCaseSourceAttribute now accepts a Category named parameter.
    * TestCaseData now supports marking individual test cases as Explicit.
    * EqualConstraint now recognizes and uses IEquatable<T> if it is implemented on either the actual or the expected value. The interface is used in preference to any override of Object.Equals(), so long as the other argument is of Type T. Note that this applies to all equality tests performed by NUnit.
    * When Assert.Throws() fails due to an exception of the wrong Type being thrown, the error message now includes the Message and Stack Trace from the exception.
    * The constraint syntax now supports Has.Exactly(n)... in place of Has.Some... in order to allow tests over collections that must be satisfied a specific number of times.
    * The Using(...) syntactic element may now be repeated multiple times in an expression, so long as each comparer applies to a different Type. NUnit will use the appropriate comparer, depending on the Type of the arguments. Among other things, this allows overriding the default NUnit comparison of collections.
    * Documentation is provided for the previously undocumented TestContext. A new property TestContext.WorkDirectory allows tests to access the name of a directory to be used for file output. This directory may be specified by use of the /work option of nunit-console.

Gui

    * The test reload functionality in the Gui has been rewritten and simplified so that the same logic is used for all cases where the visual state of the tree is to be recovered. Test results are now found even if changes to the assembly have resulted in the assignment of new ids to the tests.
    * The Gui now displays invalid tests in red immediately upon load, without waiting for the user to run them. Tests marked with the IgnoreAttribute are displayed in yellow immediately as well.
    * The directory containing the log files may be opened directly from the Gui by use of a new item on the Tools menu.
    * Test summary results are truncated when the window size is too small. The full summary is displayed when hovering over the field.
    * A number of new settings are available using the Settings Dialog:
        - The Project Editor page allows the user to select whether the NUnit Project Editor or another external program will be used when editing the settings file.
        - The Runtime Selection page allows enabling or disabling automatic detection of the target runtime for each test assembly.
        - The Advanced Loader Settings page now allows specifying the argument to use in calling SetPrincipalPolicy for each test AppDomain.
        - The Visual Studio page now includes a setting that enables or disables the use of solution configs when loading Visual Studio solution files.
        - The Internal Trace page now shows the directory path to which log files will be saved.
