c++/cli can theoretically be used with WPF/Silverlight using the trick of replacing the C# generated from the XAML with a macro definition that can be used inside the main class in a code behind file. I worked out this technique but haven’t had the motivation to take it beyond theory – I’m quite happy mixing … Read more
I’m not aware of any way to export that type. If you have to have that function signature, I would lean in the direction of using a mix of managed and native exports (managed functions using native types can’t be consumed by other languages anyway), and maybe use delay loading when calling the native exports … Read more
From MSDN: #include <string> #include <iostream> using namespace System; using namespace std; int main() { string str = “test”; String^ newSystemString = gcnew String(str.c_str()); } http://msdn.microsoft.com/en-us/library/ms235219.aspx
This is the answer of Microsoft as posted to my bug report at Microsoft Connect: Windows Server 2003 and Windows XP have problems with dynamically loading a DLL (via LoadLibrary) that uses thread-local storage, which is what thread-safe statics use internally to provide efficient execution when the static local has already been initialized. As these … Read more
It is not supported because the std::mutex implementation uses GetCurrentThreadId(). That’s a winapi function that is not supposed to be use in managed code since it might be running on a custom CLR host that doesn’t use threads to implement threading. This is the good kind of problem to have, it shows that you are … Read more
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
In C++/CLI, managed types (ref class for example) and their members are compiled to MSIL. This means no use of SIMD, and much less optimization (at least in the current version of .NET, and the reasons given by Microsoft aren’t changing any time soon, although they could change their assessment of the tradeoffs). Native types, … Read more
You have to de-tune the traditional C/C++ header file think a bit when you work with managed code. The principal source of type declarations is the assembly metadata. This is very different from the native C/C++ compilation model where you have to have a header file for types that you make visible to other modules. … Read more
Look at this solution: https://sites.google.com/site/robertgiesecke/Home/uploads/unmanagedexports The solution allows to call C# function from C by decorating your function with [DllExport] attribute (opposite of P/Invoke DllImport). Exmaple: C# code class Test { [DllExport(“add”, CallingConvention = CallingConvention.StdCall)] public static int Add(int left, int right) { return left + right; } } C code: extern “C” int add(int, … Read more
