Intellisense Name Must Be A Namespace Name
which was running perfectly. Now I copied the project to another folder and added the project to a WPF application solution. Now the C++ project is giving me lot of build errors. One of them is "System' : a namespace with this name does not exist". Below are the lines which creates this error. #include "stdafx.h" using namespace System; using namespace System::Reflection; using namespace System::Runtime::CompilerServices; using namespace System::Runtime::InteropServices; using namespace System::Security::Permissions; The above lines using namespace system visual c++ are in AssemblyInfo.cpp file. I don't have any experience of C++, so finding it difficult to remove the errors. Any help is appreciated. Below is another error which might be helpful for you to resolve the issue. managed targeted code requires a '/clr' option Thanks in advance. c++ wpf build-error share|improve this question asked May 24 '13 at 10:23 Narendra 2,02141841 Do you intend to write in C++ for .NET or natively?

I know it is C++/CLI project. But why is it giving errors when added to another solution as this does not depend upon any other project. –Narendra May 24 '13 at 10:25 2 Check in project's preferences, whether the compiler knows, that it's a C++/CLI project, because it seems, that it doesn't :) –Spook May 24 '13 at 10:31 ok, let me check –Narendra May 24 '13 at 10:34 3 Project properties | Configuration properties | General | Common Language Runtime Support. If the project is a C++/CLI one, there should be Common Language Runtime Support (/clr). –Spook May 24 '13 at 10:39 | show 3 more comme

You can do that from the UI by right clicking on your project and choosing "References". From there you can add a new reference for .NET. Alternatively you can reference the DLL directly from your code with a #using statement: #using
had been working great, then I create a new console app to try a new example in the book and started getting this error. The error points to the JuceHeader.h file, and in specific, it's pointing to the "using namespace juce;" line #ifndef __APPHEADERFILE_FTUUBP__ define APPHEADERFILE_FTUUBP include "AppConfig.h" if ! DONT_SET_USING_JUCE_NAMESPACE using namespace juce; endif namespace ProjectInfo{ const char* const projectName = "FileManip"; const char* const versionString = "1.0.0"; const int versionNumber = 0x10000;} endif // APPHEADERFILE_FTUUBP Any help will be greatly appreciated!!!
