Repairing an MM .NET Installation

After installing MM .NET 10, you should see the MM .NET Business Layer Generator available in Visual Studio (via the Extensions menu), and MM .NET project and item templates listed when creating a new project or adding items to an existing project.

If the Business Layer Generator or MM .NET templates do not appear, follow these steps to repair the installation.

Step 1: Close Visual Studio

Close all running instances of Visual Studio before continuing.

Step 2: Rebuild Visual Studio caches

Open a normal Command Prompt (administrator privileges are not required for this step), then run:

devenv /setup

Step 3: Reinstall Visual Studio templates

In the same Command Prompt, run:

devenv /installvstemplates

This forces Visual Studio to rescan and register project and item templates installed under your user Templates folders.

Step 4: Verify the Business Layer Generator extension

Launch Visual Studio and open:

Extensions ? Manage Extensions ? Installed

Confirm that MM .NET Business Layer Generator is listed and enabled. If it is missing or disabled, rerun the MM .NET installer or repair the extension from this dialog.

Step 5: Restart Visual Studio

Close and relaunch Visual Studio, then verify that:

The Business Layer Generator is available
MM .NET templates appear in the New Project and Add New Item dialogs
