Framework Migration Recommendation for Office Add-ins

Hi @Chetan Kotwal , you are now confused about whether to use React or Blazor, and your requirement is about scalability, fast development, and reduced code complexity.

In my humble opinion, you are considering Blazor Web Assembly because Blazor Server is server-side framework while Blazor Wasm is the same as React which is SPA framework. Then I need to say, Blazor Wasm is designed for C# asp.net core programmers to write frontend applications instead of using JS, but for the compatible purpose, Blazor provides options for JS to call .Net methods and for .Net to call JS methods, but most of the codes should be written in c#.

Both Blazor and React are component based. We need to create components and use them in the view, both of them are not DOM based developing, but data based developing(change data variable to control the view content, but not select the DOM then modify the HTML content) which are different than the traditional UI developing. Because of these features, both of them can meet your requirements.

So that my idea for whether we should use Blazor or not, is depending on whether your team members are working well in C# or JS. If we say we don't have develop experience in React but are familiar with asp.net core MVC, then I think using Blazor will help reduce much time for you and your team. In the meantime, we also need to take it into consideration that whether the migration only support a specific framework. Since you didn't mention too much about your add-in and the production environment, let's assume that your server is not allowed to install .Net SDK or .Net runtime, and could only install nodejs, then Blazor won't be an option for you.
