My application is targeting .net framework 4.6.2 and I use VS Express 2015.
Currently, I am using ExcelDNA 1.5.0, if update it to 1.6, 1.7 or 1.8 I get the following error trying to start the addin. If I roll back to 1.5, everything works fine.
I can see that the dll files are updated in the directory to the relevant version.
Am I missing some steps in configuration?
