'DevExpress Template Gallery Failed' error occurs

Note

Before you follow the troubleshooting process, ensure that you have .NET SDK 6.0 or later installed and you run Visual Studio 2022 or later. The support for older versions of .NET and Visual Studio has been discontinued in DevExpress ASP.NET Core Controls v22.2.

See Prerequisites and Installation for more information.

The “DevExpress Template Gallery Failed” error can occur during an attempt to create a new DevExtreme project from the DevExpress Template Gallery. This issue occurs when the Visual Studio Extension manager disables the DevExtreme Extension. Enable the extension to fix this issue:
