+## Description
+
+Updating web projects with the new 2025 Q1 assemblies for Progress® Telerik® UI for ASP.NET AJAX results in a build error related to the `TelerikLicense.vb` file. The build error `error BC30034: Bracketed identifier is missing closing ']'` occurs when trying to follow the instructions for adding the license key to the project. Additionally, the Telerik License Key view uses C# syntax, which the VB compiler does not understand.
+
+## Cause
+
+The cause of the build error is the incorrect syntax used in the `TelerikLicense.vb` file. The VB compiler does not recognize the C# syntax provided in the Telerik License Key view.
+
+## Solution
+
+To resolve the build error, use the correct VB syntax in the `TelerikLicense.vb` file. Replace the content of the `TelerikLicense.vb` file with the following VB syntax:
+
+```vb
+<Assembly: Telerik.Licensing.EvidenceAttribute("...your license code string...")>
+```
+
+Replace `...your license code string...` with your actual license code string from your Telerik account.
+
+Alternatively, to prevent licensing warnings and make the license key available to all Telerik .NET apps you develop on your local machine, follow these steps:
+
+1. Go to the [License Keys page](https://www.telerik.com/account/your-licenses/license-keys) in your Telerik account.
+2. Click the `Download License Key` button.
+3. Save the `telerik-license.txt` file to one of the following directories on your local machine:
+   - `%AppData%\Telerik\telerik-license.txt` (e.g., `C:\Users\...\AppData\Roaming\Telerik\telerik-license.txt`)
+   - `C:\inetpub\wwwroot\telerik-license.txt`
+   - `C:\inetpub\telerik-license.txt`
+   - `C:\telerik-license.txt`
