MissingMethodException after updating visual studio to latest

[Glayson Patricio]

Hi everyone.

This week I updated visual studio and all the nuget packages from microsoft used in my solution, and now I am getting the exception below:

"MissingMethodException: Method not found: 'Void System.Windows.Forms.Control.set_Font (System.Drawing.Font)'

From:
ExcelDna.Logging.LogDisplayForm.LogDisplayForm()

ExcelDna.Logging.LogDisplayForm.ShowForm()

Visual studio also updated the .net 6 version to latest.

Any tips on what could be going on ?

Is anyone getting similar errors ?

Thanks, Glayson

Hi Glayson,

 

I tried an add-in targeting .NET 6, with this function:

 

        public static string SayHello(string name)

        {

            LogDisplay.WriteLine("Hey there!");

            LogDisplay.Show();

            return "Hello " + name;

        }

 

It works fine for me.

 

I running ExcelDna.AddIn v1.6.1-alpha6, VS 2022 v17.4.0 and .NET v6.0.11.

 

What are your versions?

Govert,

Thankyou very much for your support, reading and helping us with every question!

I stayed the last few days doing several types of tests (reinstalling visual studio, net 6.0, net 7.0, downgrading the nuggets, etc...)

And I was able to find the what is causing the problem.

The problem is caused when I Upgrade the Nuget SYSTEM.DATA.OLEDB from version 6.0.0 To 7.0.0

when the 7.0.0 version is used, several new files are created at the "runtimes/win/lib/net6.0" folder.

one of them is the "System.Drawing.Commom" which i believe is the cause of the problem.

After downgrading this package, everything seems normal again.

Thankyou very much.

Glayson
