I'm trying to depoly an Excel-Addin (VSTO) with ArcGis dotnet SDK 100.0.0 which projects coordinates.
If I deploy the addin, the RuntimeCore is not copied /installed on the pc and the Esri.ArcGISRuntime.Geometry doesn't work?
How can I achieve this?
Could you try a newer version? I believe v100.0 didn't add the required DLLs as content, but just did an xcopy deploy, so other packaging tools didn't realize they had to be included as well.
If that doesn't help, you'll need to make sure your add-in installer deploys the contents of the ArcGISRuntime100.x folder yourself.
