Updated my NuGet Packages from 1.7 to 1.9.2-beta, now I am gettting an error

[Rand Random]

On the line

var x = ExcelDnaUtil.Application;

I am getting the error

Cannot find the interop type that matches the embedded interop type 'Microsoft.Office.Interop.Excel.Application'. Are you missing an assembly reference?

what am I doing wrong?

That error is unexpected, but we did do some refactoring that changed the return type to reflect the real COM interface.

I think this would be fixed if you add a reference to the "ExcelDna.Interop" NuGet package.

Added the mentioned NuGet package, but temporarily I got these different errors

The "LoadFromBytes" parameter is not supported by the "CreateExcelAddIn" task loaded from assembly: ExcelDna.AddIn.Tasks, Version=1.1.0.0, Culture=neutral, PublicKeyToken=f225e9659857edbe from the path: xxx\exceldna.addin\1.8.0\tools\net452\ExcelDna.AddIn.Tasks.dll. Verify that the parameter exists on the task, the <UsingTask> points to the correct assembly, and it is a settable public instance property.

The "CreateExcelAddIn" task could not be initialized with its input parameters.

Since the error message said version "1.8.0" I believe there was just some cache issue, from me playing around with the different versions, and a re-build solved the issue.

So thanks, yes adding the ExcelDna.Interop NuGet package did solve the problem.
