InvalidProgramException in Windows Forms application

Vadym Lenda 20

Hello,

I'm a developer of the desktop .NET Windows Forms application.

I faced a strange exception thrown by .NET runtime on a single production PC.

On a component initialization phase .NET throws the following:

System.InvalidProgramException: Common Language Runtime detected an invalid program.    at System.Windows.Forms.DataGridViewColumnCollection.GetColumnAtDisplayIndex(Int32 displayIndex)    at System.Windows.Forms.DataGridView.CorrectColumnFrozenState(DataGridViewColumn dataGridViewColumn, Int32 anticipatedColumnIndex)    at System.Windows.Forms.DataGridView.OnAddingColumn(DataGridViewColumn dataGridViewColumn)    at System.Windows.Forms.DataGridViewColumnCollection.Add(DataGridViewColumn dataGridViewColumn)    at System.Windows.Forms.DataGridView.CorrectColumnFrozenStates(DataGridViewColumn[] dataGridViewColumns)    at System.Windows.Forms.DataGridView.OnAddingColumns(DataGridViewColumn[] dataGridViewColumns)    at System.Windows.Forms.DataGridViewColumnCollection.AddRange(DataGridViewColumn[] dataGridViewColumns)

What can cause the issue?

Where to dig to find a root cause?

Has anyone faced the same problems with Windows Forms?

Any information is highly appreciated.

Vadym.

Hi @Vadym Lenda , Welcome to Microsoft Q&A,

From the error message, it seems that you are creating columns in winform datagridview? Try removing AddRange column code in designer.cs file. Convert direct additions to code additions. If it is an unintentional error, can try clean and rebuild project to fix it? Can recreating a project reproduce the error?

Hi, @Jiale Xue - MSFT ,

yes, I'm using windows forms DataGridView to display some information in grid.
I'm using designer to create columns in grid, so this is a default code generated by a windows forms designer.

Could you please explain more what do you mean by "Convert direct additions to code additions" ?

AddRange method is called in code behind class of view.

Rebuilding project won't help because this error is not reproduced on dev machines.

Out client has a lot of production PCs, and this error is reproduced on a single production PC.

According to exception description (InvalidProgramException) it's related to invalid MSIL code inside a dll. As long as stack trace points to a Windows Forms inner method, could it be related to a broken .NET installation?

Can I somehow check the integrity of .NET installation?

Besides, as far as I know .NET dlls are deployed using ngen to generate native images and loaded into process from NIC (native images cache). How a native image can throw an exception related to invalid MSIL?

there should be no MSIL inside..

Please, advice.

Hi @Vadym Lenda ,

Since this error cannot be reproduced, can you fix it by removing the DataGridview. Or recreate a WinForms project to fix it?

You can try to fix it in the installer program. You can also delete clr and reinstall it.

If you use vs2022, you can also revert to a previous version without problems in the installer.

@Jiale Xue - MSFT ,

On a PC where the problem is reproduced there's no visual studio installed, it's not a dev machine it's a production machine.

Is it possible to repair or reinstall somehow a .NET runtime on a production machine (Win 10) ?

Accepted answer

Hi @Vadym Lenda ,

You can of course fix the .NET runtime directly in your production environment.

This is the official documentation for .NET runtime.Install .NET on Windows.

If you want to delete the previous runtime, you can refer to this document：How to remove the .NET Runtime and SDK.

Best Regards,

Jiale

@Jiale Xue - MSFT

thank you for your replies.

Sorry, I didn't mention, we use .NET Framework (4.6.2) as a target runtime, not .NET.

So, the first question is the same: can I repair or reinstall .NET Framework runtime on a Windows 10 machine (remove old and install a new one)?

Second question:

.NET Framework runtime uses ngen to compile native images, which then are used in runtime as dependency, is it possible to force native images regeneration for .NET Framework runtime?
