Problem migrating to NetofficeFW

[ilens]

I have removed fhe old references NetOffice v1.7 from my project and used the Package Manager to install NetofficeFW v 1.8.1
I have then changed "Imports excel=Netoffice.excel" to "Imports excel=NetofficeFW.excelAPI" but Visual Studio says that this Type does not include any public members or cannot be found. The project file includes the statements

False
True
..\PCS_Structure\packages\NetOfficeFw.Excel.1.8.1\lib\net40\ExcelApi.dll

and the dll exists at that location.

The NuGet package manager also shows tha package is installed

What have I done wrong?

Please, learn about using packages in Visual Studio. This is out of scope of this project.

I have done so and the ExcelApi only has a .utils member
