Use AssemblyName and not ProjectName for the runtimeconfig.json

[Rand-Random]

ExcelDna/Source/ExcelDna.AddIn.Tasks/CreateExcelAddIn.cs

Line 403 in 8ae443f

result = result.Replace("<DnaLibrary ", "<DnaLibrary " + $"CustomRuntimeConfiguration=\"{ProjectName}.runtimeconfig.json\" ");

Image a csproj where the user sets a custom AssemblyName
ProjectName = MyAddIn
AssemblyName = Company.MyAddIn

the produced runtimeconfig.json will be

Company.MyAddIn.runtimeconfig.json and not just simply MyAddIn.runtimeconfig.json.
