Hello,
I want to read Powerpoint with a c# code. There are MsoTrue and MsoFalse types in the code. Therefore, I will put 2 variables of type MsoTriState in the invoke code.
I wrote Microsoft.Office.Core.MsoTriState.msoTrue as variable value, but I get the warning in the picture.
My xaml file contains Microsoft.Office.Core and Microsoft.Office.Interop.Powerpoint.
Can you help, I can’t find the solution for this for a long time?
By the way, I added the MsoTriState data type as follows.
Can you show us the dependencies like:
was any balareva / other office relateted packages also referenced?
FYI
Hello;
Dependencies in that;
For security reasons, I cannot use individual packages. 
Thank you.
Hello,
can you help? I still haven’t been able to solve the problem.
can you show us your imprted namespaces (import panel). Thanks
Hi @258b68b4092270201fa0f6a77,
As @ppr said, you have to import the correct namespaces.
var FullFilePath= InputFullFilepath;
var app = new Microsoft.Office.Interop.PowerPoint.Application();
var ppt = app.Presentations.Open(FullFilePath, WithWindow: Microsoft.Office.Core.MsoTriState.msoTrue);
Sample file: MsoTriState.xaml (5.5 KB)
