Is System.Runtime.Serialization.FormatterServices available in metro style apps?

Question

Hi,

mainly I am interested in System.Runtime.Serialization.FormatterServices.GetUninitializedObject function? 

In my application, I am performing following steps:

* Create uninitialized object by calling System.Runtime.Serialization.FormatterServices.GetUninitializedObject from C++

* Read some data from specific file in C++, and fill the data to my newly created object using Marshalling.

* Execute default constructor through reflection.

I couldn't found this class or function in .Net for Metro apps, but I was able to get System.Runtime.Serialization.FormatterServices through reflection while running my Metro app, and I am not totally sure what's going on? Is the class somehow hidden, or am I using this class from non-metro mscorlib.dll ?

In any case, if I am wrong by using System.Runtime.Serialization.FormatterServices, can you suggest a different method how can I create unintialized object.

P.S Activator.CreateInstance is no good, because 1, 3 steps will perform before 2nd step which is bad for me.

Thanks!

Hello,

 

The C++ in metro is different from the native C++. The data in C++ wrapped with WinRT, will have more convenient way to communicate with other language like C# or JavaScript.

 

Please check this document

Hi, 

I was a bit unclear, actually I am using a WinRT component, but it's written in C#, I am using it from my main executable written in C++, and I was wondering is  System.Runtime.Serialization.FormatterServices stripped from .Net for Metro or not?

Thanks.

You could use Google's protobuf, wich is available in a variety of languages.
