I'd like to give U++ a serious try but I need to integrate with a few .net libraries (On Windows). I am wondering if anyone has tried to combine /clr (managed c++) code with the U++ framework and TheIde?
Regards,
Conrad

Let's create simple "Core console project" application:
#include <Core/Core.h>
using namespace Upp;
#using <mscorlib.dll>
using namespace System;
CONSOLE_APP_MAIN
{
Cout() << "Hello, from U++!\n";
Console::WriteLine("Hello, from managed C++!");
}
Open "Project -> Package organizer.." for main package and insert following compiler option:
-clr
Open "Project -> Main package configuration.." menu and add following build flags:
EVC .USEMALLOC
EVC - is build flag (used for another C++ compiler), which adds compiler options to turn off exception handling, because -clr is not compatible with -EHsc compiler option.
USEMALLOC - disables U++ memory allocator to not conflict with .NET Framework memory allocation methods.
Also check "Build -> Output mode.." menu for the "Use shared libs" link mode.
Now, you can build combined U++ and Managed C++ package.
To note:
It also possible to extend C++ syntax higlighting for managed C++ extensions and add CLR specific compiler options, instead of EVC.
Here, I just showed possible way to use TheIDE with Managed C++ extensions. I don't think, this is recommended way.

Many thanks for all the answers here.
I must say, I have rarely if ever experienced such support.
I will give this a try this week.
I have a fair amount of experience with mixed mode solutions running in VS 2009 and 2010.
The system I need to make work is one I call for the "firewall" solution. Let me explain.
I do not want the entire app to bee "seen" by the /clr compiler but only a wrapper "project" (a Package ?). The reason for this is that once the application grows, mixed mode compilation & linking becomes completely unmanageable. Footprint is 2.5 times fold and link times can be literally hours.
For this to work, a few .h header files will have to be compatible for both c++ and /clr compilation. With VS 2010 doing the compilation, std::string and std::wstring is for example a workable candidate. In a VS solution, these wrapper classes live in a unique project and only this project has /clr turned on. /clr only, not /pure, not /safe - as these create far too many issues. But /clr works, and I know for a fact that given a few wrapper classes where essentially plain old data and strings are converted from the .net world to the c++ world, mixed mode can have much to offer.
I will let you know how I am doing as soon as I know a bit more.
Again, thanks for the support here without which I may not have had the courage to give it a try

I understand the concept of Packages a bit better now.
I made a "DotNetWrapper" package with -clr.
It looks like I need a way to pass on more compiler options to VS.
In particular the /MDd option must override the /MTd option.
(Adding -EHa seems to work, but adding -MDd doesn't)
I am using the HelloWorld example.
I don't think I need to change the default setting of the application. Only the wrapper package must be build with correct options.
I have read Miroslav's http://www.ultimatepp.org/redmine/issues/156 and looked at the diffs but that is going a bit too fast for me Besides, looks like I would have to recompile theIde first after pull in those changes.
Regards,
Conrad
