Google.OrTools exception C# framework 4.7.2

[KeramatHasani]

I have installed the package Google.OrTools via NuGet but running the test program Visual Studio see this exception:
System.BadImageFormatException: 'Could not load file or assembly 'Google.OrTools, Version=7.0.6546.0, Culture=neutral, PublicKeyToken=53dbb1ea090cbef7' or one of its dependencies. An attempt was made to load a program with an incorrect format.'

Which test program ? Are you using a Windows 64bits (i.e. what is your runtime platform) ?

[KeramatHasani]

I tried to run ShiftScheduling.cs
Yes it is 64 bit

note on windows Google.OrTools depends on Google.OrTools.runtime.win-x64

does it works if using the dotnet cli directly ?
note: on my way to test too

I tried many times. But each time I see this exception:
Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Google.OrTools, Version=7.0.6546.0, Culture=neutral, PublicKeyToken=53dbb1ea090cbef7' or one of its dependencies. The system cannot find the file specified.

Can you check that visual studio c++ redistributables are installed. Maybe they are not if you just install the C# layer. Laurent Perron | Operations Research | lperron@google.com | (33) 1 42 68 53 00 Le jeu. 11 avr. 2019 à 18:14, Alvin <notifications@github.com> a écrit :

Visual Studio C++ redistributables 2017 (x64) are installed.

Create a pet project to "consume" Google.OrTools nuget package

This use the Appveyor VS 2017 worker image

The problem solved at last through migration to a new project on .Net Framework 4.7.2 and installing the latest version of google or-tools and running x64. Thanks @lperron @lperron
