public static bool IsRunningInUnitTest()
{
    // Checks if common test runners are loaded in the process
    return AppDomain.CurrentDomain.GetAssemblies().Any(a => a.FullName != null && a.FullName.StartsWith(\"xunit\"));
}

The XML comment claims "common test runners" but the implementation only matches assemblies whose FullName starts with xunit. NUnit (nunit.framework), MSTest (Microsoft.VisualStudio.TestPlatform, MSTest.TestFramework), and TUnit are not detected.

Callers (DependenciesViewModel.cs:283, ServiceSearchViewModelBase.cs:130) use this guard to skip Dispatcher invocation in unit tests. Anyone running these ViewModels under NUnit/MSTest will hit Application.Current.Dispatcher calls outside a Dispatcher pump, producing flaky test failures or null-ref warnings.

Suggested fix: match any of the common test framework prefixes:

private static readonly string[] TestFrameworkPrefixes =
{
    \"xunit\", \"nunit.framework\", \"Microsoft.VisualStudio.TestPlatform\",
    \"Microsoft.TestPlatform\", \"MSTest.TestFramework\", \"TUnit\"
};

public static bool IsRunningInUnitTest()
{
    return AppDomain.CurrentDomain.GetAssemblies().Any(a =>
        a.FullName != null && TestFrameworkPrefixes.Any(prefix =>
            a.FullName.StartsWith(prefix, StringComparison.OrdinalIgnoreCase)));
}

The current Servy test suite is xUnit-only, so this is dormant; rename to IsRunningUnderXunit if you want to keep the narrow scope, or expand the detection to match the doc comment.
