Spacing problem of namespaces in C++ unit testing

[lucky6969b]

    Code:

    #include "stdafx.h"

    using namespace System;
    using namespace System::Text;
    using namespace System::Collections::Generic;
    using namespace Microsoft::VisualStudio::TestTools::UnitTesting;
     

    namespace PerfectSimTest1
    {
    	[TestClass]
    	public ref class CGameApplicationTest
    	{
    	private:
    		TestContext^ testContextInstance;

    	public: 
    		/// <summary>
    		///取得或設定提供目前測試回合
    		///的相關資訊與功能的測試內容。
    		///</summary>
    		property Microsoft::VisualStudio::TestTools::UnitTesting::TestContext^ TestContext
    		{
    			Microsoft::VisualStudio::TestTools::UnitTesting::TestContext^ get()
    			{
    				return testContextInstance;
    			}
    			System::Void set(Microsoft::VisualStudio::TestTools::UnitTesting::TestContext^ value)
    			{
    				testContextInstance = value;
    			}
    		};

    		#pragma region Additional test attributes
    		//
    		//您可以在撰寫測試時，使用下列的其他屬性:
    		//
    		//在執行類別中的第一項測試之前，先使用 ClassInitialize 執行程式碼
    		//[ClassInitialize()]
    		//static void MyClassInitialize(TestContext^ testContext) {};
    		//
    		//在執行類別中的所有測試之後，使用 ClassCleanup 執行程式碼
    		//[ClassCleanup()]
    		//static void MyClassCleanup() {};
    		//
    		//在執行每一項測試之前，先使用 TestInitialize 執行程式碼
    		//[TestInitialize()]
    		//void MyTestInitialize() {};
    		//
    		//在執行每一項測試之後，使用 TestCleanup 執行程式碼
    		//[TestCleanup()]
    		//void MyTestCleanup() {};
    		//
    		#pragma endregion 

    		[TestMethod]
    		void RunTest()
    		{
    			CGameApplication;
    			CGameApplication^ oCache = gcnew CGameApplication();
    			oCache->Run();
    			//
    			// TODO: 在此加入測試邏輯
    			//
    		};
    	};
    }

The error being is CGameApplication can't be recognized, undefined or something.
There is a space in between the project name such as "Simulation V2.0"
When I do,
using namespace Simulation V2.0 or using namespace "Simulation V2.0", the compiler complains.
I have made a reference in the .NET section of the test project to no avail
Please help
Thanks
