Need help: Odd behavior when calling a 3rd party library

[dhaverstick]

I have an Inventor addin that I recently added some functionality to. To make some calculations that I needed to make, I referenced the MathNet.Spatial library that I downloaded as a NuGet package. The Inventor addin compiles without issue and I made sure there was a copy of the MathNet.Spatial dll in the addin installation directory. However, when I try to run the addin, I get an error telling me "Could not load file or assembly 'MathNet.Spatial, version= blah, blah, blah' or one of its dependencies. The system cannot find the file specified."

Does anyone have any ideas why this dll cannot be found/loaded?

Thanks in advance,

As I stated in my original post, the MathNet dll files are in the same directory as my Inventor addin dll.

@dhaverstick,

Check the supported .net framework of MathNet.Spatial.dll with version of Inventor. Usually, if framework is not matching. This kind of error may appear.

Thanks and regards,
