Cross-Browser Compatibility Issues in ASP.NET Core Blazor Application

blazor cross-browser aspnetcore C#

I'm migrating some code and Currently developing an ASP.NET Core Blazor application that needs to function across various browsers, and I’ve run into several challenges. While testing on Chrome, Firefox, and Edge, certain components render differently or throw unexpected errors. For instance, a DatePicker component displays correctly in Chrome but shows an invalid date format in Firefox. My implementation uses the following code: ```csharp <DatePicker @bind-Value="selectedDate" Format="yyyy-MM-dd" /> ``` This inconsistency has prompted me to check the underlying JavaScript that handles date parsing. I found that the JavaScript Date object behaves differently across browsers, especially with locale settings. As a workaround, I tried using a third-party library like 'moment.js' to handle the formatting: ```javascript const formattedDate = moment(selectedDate).format('YYYY-MM-DD'); ``` Despite this change, I still see issues, particularly in older versions of Safari, where the component fails to initialize without throwing a clear error message. My attempts at adding polyfills did not yield the desired compatibility. I have also configured the application to target .NET 6, and I ensure that my browser targets are set correctly in my project file: ```xml <TargetFramework>net6.0</TargetFramework> <RuntimeIdentifier>win-x64;linux-x64</RuntimeIdentifier> ``` Looking for the best way to ensure consistent behavior of components across different browsers, has anyone successfully navigated similar compatibility issues within Blazor? Any recommendations for debugging strategies or libraries that seamlessly handle cross-browser quirks would also be appreciated. My development environment is Ubuntu. Thanks in advance! This is part of a larger web app I'm building. I'd really appreciate any guidance on this. I'm developing on Linux with C#. Any pointers in the right direction?
