Call function from dll in metro app

Question

Hi All,

I want to call function from dll in metro app using C++.

In dll function, I want to do file operations. So I create Metro app DLL.

In this dll function, I am creating file and write some data in it.

When I call this function from metro app, file is created but metro app crashed.

I am using CreateFileAsync(), WriteTextAsync() functions for file operations.

What will be the problem? What extra I need to do to achieve this?

If anyone have idea about it, then please help me, waiting for reply.

Thanks,

Pariksheet.

Answer 1

Run it from Visual Studio and the debugger should give you more info there.

Hi,

Thanks for your replies.

There was problem with debug configuration.

It's working with release configuration.
