As backend code, yes. As a web (web, not api. As an api platform they’re great) platform… No. Asp.net and mvc were imo a disaster, silverlight was… Oof. Then there is maui which could have done it using blazor but just… Didnt. … And then there is blazor itself. Though blazor is imo the best of all the web platforms they had, and i like it, it still has very rough edges and is not gonna replace javascript any time soon. Hell, microsoft cant even decently support their own web ui platform ( fluentui ) because their backbone ( webcomponents ) is completely broke ( or did v3 FINALLY release? ). There are other platforms but they all seem to not take full advantage of blazor and its disgusting.
