I'm using Visual Studio 2015 and OpenStudio 1.9.0, but can't seem to get any of the example c# files or my own to run. I've followed this answer setting my path correctly and build configuration for a 64-bit machine, but I keep getting a System.TypeInitializationException occuring in OpenStudio.dll. The exception is thrown at OpenStudio.OpenStudioUtilitiesCorePINVOKE and the inner exception states that it's unable to load openstudio_OpenStudioUtilitiesCore_csharp.dll. Any thoughts?

@MarkAdams, I just saw this post here, is using Visual Studio 2015 an issue on OpenStudio 1.9.0 or 1.9.3?

@pflaumingo Visual Studio 2015 should be okay when using the C# bindings, but it does not work when compiling OpenStudio itself. I just tested with OpenStudio 1.9.0, Visual Studio 2015 Enterprise, and the code (and instructions) from here, and it all works. I don't know what to say other than follow my instructions in that other post and if that still fails to maybe post example code.

Hmm, very odd as I've just copied your sample code (and changed the path). I'll figure it out.

I believe you have to either copy all the dlls from your OpenStudio install into your build directory or add the path to the OpenStudio dlls to your path. The path to copy dlls from is:

C:\Program Files\OpenStudio 1.9.0\CSharp\openstudio

Depending on what features you try to use from OpenStudio you may also need to copy some Qt plugins or other file resources.

Yeh, I've added the path to my environment variables listed in the link I posted, but still no luck. Typing 'path' in the command prompt also shows it's in the path. I could probably add it to the build directory, but I was hoping to avoid this.

Did you include both C:\Program Files\OpenStudio 1.9.0\bin; and C:\Program Files\OpenStudio 1.9.0\CSharp\openstudio; in your path?

Check that you are building a 64 bit C# application if you are using the 64 bit OpenStudio dlls. After that, I have found Dependency Walker to be useful here, see this tutorial.

@MarkAdams, yup, I've checked a few times and I've got them both. @macumber, I've tried both 32-bit and 64-bit builds, but neither worked. Also, I used dumpbin on OpenStudio.dll and it looks like it is 32-bit even though my OpenStudio download is 64-bit. If my path is set up correctly as @MarkAdams shows I should just be able to type 'OpenStudio' in a command prompt and it should launch, right?

I ended up uninstalling and reinstalling and everything works fine now.
