Unable to login to Vault 2025 with .net 8 Console App

[mfoster9TD82]

Hello, 
I'm in the process of converting my Vault apps to .net 8 but I've run into this exception and haven't been able to find anything about it.
When trying to login with the dialog box in a console app with:

Autodesk.DataManagement.Client.Framework.Vault.Forms.Library.Login(...)

I keep getting this exception thrown:

Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I've added all the requirements mentioned in this post and I've added the System.Drawing.Common package, and still nothing.

It works just fine in a WPF and WinForms, just not console app.

Is there a way to login to vault with the dialog box with a console app, or do I need to use a different method? I need to use windows Authentication to login to vault, and the dialog box has been the easiest way of doing that.

Did you compare the .NET 8 login samples posted with this Blog?

You may try to leverage this code for the console application: 

            mServerId.DataServer = this.txtServer.Text;
            mServerId.FileServer = this.txtServer.Text;
            mUserName = this.txtUserName.Text;
            mPassword = this.txtPassword.Text;
            mVaultName = this.txtVaultName.Text;
            ACW.LicensingAgent mLicAgent = ACW.LicensingAgent.Client; //Client | Server | None
            ACWTools.WebServiceManager? mVault = null;

            ACWTools.WinAuthCredentials winAuthCredentials = new ACWTools.WinAuthCredentials(mServerId, mVaultName, null, mLicAgent);

            try
            {
                mVault = new ACWTools.WebServiceManager(winAuthCredentials);
            }
            catch (Exception)
            {
                mUserFeedback(null);
                return;
            }

            // get connection
            conn = new Vault.Currency.Connections.Connection(mVault, mVaultName, mVault.SecurityService.Session.User.Id,
                mServerId.DataServer, Vault.Currency.Connections.AuthenticationFlags.Standard);
