[severity:I'm unable to use this version] [regression]
After upgrading to the latest Visual Studio 2026 (March Update), I started a new Blazor project and add the Nuget package for Radzen Blazor Components - running through the Getting Started instructions to have Radzen properly configured, I tried the sample component. Despite having the button nicely displayed, it did not fire the click event. Carry several tests to check it but as I rendered unable to proceed, I'm rolling back.

Reproduce this with a new Blazor project in Visual Studio 2026 (March Update), add the Radzen Blazor Components NuGet package, and follow Radzen's Getting Started instructions. Verify whether the sample button renders but its click event does not fire, then compare the result with the reported rollback behavior.
