[gel]

Is there any time estimate on it?

Anything on this one?

Is there a working branch for this issue? Attempts to retarget projects seem to generate unspecified errors:

Upgrading project 'ActionsLib'...
    Configuration 'Debug|x64': changing Platform Toolset to 'v140' (was 'v120').
    Configuration 'Release|x64': changing Platform Toolset to 'v140' (was 'v120').
    Configuration 'Release_CpuOnly|x64': changing Platform Toolset to 'v140' (was 'v120').
    Configuration 'Debug_CpuOnly|x64': changing Platform Toolset to 'v140' (was 'v120').
One or more errors occurred.
Retargeting End: 1 completed, 0 failed, 0 skipped

after retargeting the build still fails:

1>------ Build started: Project: ActionsLib, Configuration: Debug_CpuOnly x64 ------
1>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.Cpp.Platform.targets(57,5): error MSB8020: The build tools for v120 (Platform Toolset = 'v120') cannot be found. To build using the v120 build tools, please install v120 build tools.  Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-click the solution, and then selecting "Retarget solution".

CUDA 8 seems to support VS2015. Is the dependency in CUDA 7.5 preventing the migration to VS2015? Or there are many additional dependencies?

[bklooste]

Still looks pretty broken . Is there a new branch ? Anyone got this working without installing old VS ?

We are working it and will make CNTK support CUDA 8 (coming first) and VS2015 soon.

Closing, VS2015 support is now on master, from d927e81 onwards.
