It is 2018. The project fortunes have changed quite a bit. CefSharp is alive and well with almost daily updates in the GitHub depository. Issues are getting resolved, currently only 57 open issues and 1787 closed. CefGlue does not seem to do well. The mailing lists are moribund, there have not been recent updates. There … Read more

Yes, C++/CLI has a very specific target usage, the language (and its compiler, most of all) makes it very easy to write code that needs to interop with unmanaged code. It has built-in support for marshaling between managed and unmanaged types. It used to be called IJW (It Just Works), nowadays called C++ Interop. Other … Read more
You can do this fairly easily. Create an .h/.cpp combo Enable /clr on the newly create .cpp file. (CPP -> Right click -> Properties) Set the search path for “additional #using directories” to point towards your C# dll. Native.h void NativeWrapMethod(); Native.cpp #using <mscorlib.dll> #using <MyNet.dll> using namespace MyNetNameSpace; void NativeWrapMethod() { MyNetNameSpace::MyManagedClass::Method(); // static … Read more
Have you take a look at C++/CLI? Let me give a very short example. Here is the source file from a Visual C++ -> CLR -> Class Library project. It basically get Windows username and return it. Please note that, in order to get this compiled, you have to go into project settings and mark … Read more
gcnew is for .NET reference objects; objects created with gcnew are automatically garbage-collected; it is important to use gcnew with CLR types
See this blog posting: http://blogs.msdn.com/ericlippert/archive/2009/06/22/why-doesn-t-c-implement-top-level-methods.aspx (…) I am asked “why doesn’t C# implement feature X?” all the time. The answer is always the same: because no one ever designed, specified, implemented, tested, documented and shipped that feature. All six of those things are necessary to make a feature happen. All of them cost huge amounts … Read more
To display a wstring you also need a wide version of cout – wcout. std::wstring st = L”SomeText”; … std::wcout << st;
As Patrick O’Hara wrote, NuGet will not make changes to a C++/CLI project for you. See GitHub Issue NuGet/Home#1121 – Cannot install managed packages into a CLI project. However, using the NuGet command line utility, NuGet.exe, you can have NuGet download and unpack the desired package(s). For a complete example, here were steps that I … Read more
Don’t roll your own, use these handy (and extensible) wrappers provided by Microsoft. For example: #include <msclr\marshal_cppstd.h> System::String^ managed = “test”; std::string unmanaged = msclr::interop::marshal_as<std::string>(managed);
