api-ms-win-core-libraryloader-l1-2-0.dll is missing

Question

Tuesday, September 8, 2015 5:37 AM

I build a exe and checked the dependencies with dumpbin /DEPENDENTS myexefile.exe.

The output shows me some of the api-ms-win-core dlls are missing.

For example:

api-ms-win-core-libraryloader-l1-2-0.dll is missing. On Windows 10 computer and IoT device only api-ms-win-core-libraryloader-l1-1-0.dll is available. There are some other dll's I can't find:

  • api-ms-win-core-libraryloader-l1-2-1.dll
  • api-ms-win-core-rtlsupport-l1-2-0.dll
  • api-ms-win-core-interlocked-l1-2-0.dll
  • api-ms-win-core-namedpipe-l1-2-0.dll
  • api-ms-win-core-heap-l1-2-0.dll

What is wrong here?

Hi,

did you try the following step?

A Universal Windows Platform (UWP) app or Windows Runtime Component written in C++/CX has access to the Win32 APIs that are part of the Universal Windows Platform (UWP). These Win32 APIs are implemented by all Windows 10 device families. Link your app with Windowsapp.lib. Windowsapp.lib is an "umbrella" lib that provides the exports for the UWP APIs. Linking to Windowsapp.lib will add to your app dependencies on dlls that are present on all Windows 10 device families.

Hello,

I know this page and already had a look at it. This is related to my question about which lib to use in the form here:

https://social.msdn.microsoft.com/Forums/en-US/0c0d07a7-5730-401a-9b18-51136000836f/differences-between-mincorelib-oncorelib-oncoreuaplib?forum=WindowsIoT.

I used Windowsapp.lib and mincore.lib. I am wondering how this works, becaus I can not find Windowsapp.lib on my computer?

According to the API Set description the api-ms-win-core-libraryloader-l1-2-0.dll shoud be availabl on my IoT device, right?

How can we arrange to get in contact with Microsoft, because we have some more general questions about Windows IoT?

Regards

Markus
