managed incremental build
Managed Incremental Build

A.dll

A.Dll

ClassB b;

b.f()

B.meta

B.dll

B.meta(*)

B.Dll

public ref class ClassB {

public String f() {

//important string here

return “Important String”;

}

}

Skip projects with no “significant” changes since last build

marshaling
Marshaling
  • New library to simplify passing data between native and managed code
  • Template-based pattern that applies to any kind of data
  • Support lots of types out-of-the-box
stateless transition
Stateless Transition
  • I want to marshal between managed and native data types for conversions that do not require any lifetime management or complex resource allocation

#include <msclr/marshal.h>

using namespace msclr::interop;

{

const char* sourcestring1 = “teststring”

System::String^ deststring1;

// Convert const char* to System::String^ using

// TO to = marshal_as <TO> (from)

deststring1 = marshal_as<System::String^>(sourcestring1);

}

stateful transition
Stateful Transition
  • I want to marshal between managed and native data types for conversions that require some kind of lifetime (memory, resource, etc…)

#include <msclr/marshal.h>

using namespace msclr::interop;

{

System::String^ sourcestring1 = “teststring”

const char* deststring1;

//Convert System::String^ to const char* using

//TO to = context.marshal_as<TO>(from)

marshal_contextctx;

deststring1 = ctx.marshal_as<const char*>(sourcestring1);

}

stl clr
STL/CLR
  • Leverage STL skills in applications that use .NET Framework
  • Ease data exchange between STL and .NET Collections
  • The power of templates and generics together
    • Designed to achieve optimal performance and cross-language compatibility
    • STL in any part of managed code (but only C++)
class designer
Class Designer
  • Only does visualization of code
