Description

This issue has been moved from a ticket on Developer Community.

[severity:It's more difficult to complete my work] If I type Dim followed by a space, VS changes the Dim to DataImport. This is the latest deterioration of intellisense in VB.Net, it has been going on for a long time, there are countless issues with it. Please fix this.

Research direction
The issue describes a bug where typing 'Dim' in VB.NET causes Visual Studio to replace it with 'DataImport'. The maintainer asked for reproduction steps, project type, and a video, but the user has not responded. Investigate the Roslyn codebase for intellisense handling of VB.NET keywords, particularly in the IDE layer. Look at linked PRs or comments for similar issues. The issue was migrated from Developer Community.
