# Scaffolding

This page provides solutions to common issues you may encounter while working with the [Telerik UI Scaffolder](https://www.telerik.com/aspnet-mvc/documentation/vs-integration/scaffolding) Visual Studio extension.

## Common Scaffolding Issues

### New Scaffolded Item Menu Is Not Displayed When Right-Clicking Project Locations

**Solution**

* Make sure that you use a compatible Visual Studio version and that all listed requirements are fulfilled.
* Check if the Telerik UI Scaffolder extension is listed in the **Tools** > **Extensions and Updates** list.

### Data Context Class DropDownList Is Empty

**Solution**

Make sure that the current project contains a valid **Entity Framework Data Model**. If this is true, rebuild the solution.

### Invalid Model Configuration Error Is Thrown When Running the Scaffolder

The most probable reason for this error is that the selected **Model Class** is not a valid entity in the current **Data Context**.

**Solution**

Make sure that a valid entity is selected.
