c# - 在哪里可以找到 "Microsoft.VisualStudio.TestTools.UnitTesting"丢失的 dll？

Question

我在 C# visual studio 项目中遇到以下错误:

The type or namespace name 'VisualStudio' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)

我也试图找到 microsoft.dll 文件，但找不到任何引用。我是否搜索了错误的 DLL？

using Microsoft.VisualStudio.TestTools.UnitTesting;  
using Kya.MsFx.Services.Swiper;

namespace Kya.MsFx.Devices.Swiper.Test
{
[TestClass]
public class SwiperWindowTest
{

    private SwiperWebServiceHost m_SwiperWS = null;
    /// <summary>
    ///     start web service on a separate thread, so tests 
    ///     can be executed withut blocking the application thread
    /// </summary>
    [ClassInitialize]
    public void SetupSwiperTests() {

        m_SwiperWS = SwiperWebServiceHost.StartService();

    }

    /// <summary>
    /// Stop service started during class initialize and kill the thread
    /// </summary>
    [ClassCleanup]
    public void CleanupSwiperTests() {
        m_SwiperWS.Stop();
    }


    /// <summary>
    ///   simulate init, swipe, clear operations
    /// </summary>
    [TestMethod]
    public void TestSwiperService()
    {
        MessageBox.Show("test");
    }
}
}

你必须添加引用

Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll 

可以在C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\PublicAssemblies\目录下找到(VS2010专业版或以上；.NET Framework 4.0)。

或右键单击您的项目并选择:添加引用... > .NET:
