As someone who programs with .NET in their day job...no probably, not.
Outside of a few areas related to DDD, event sourcing, and some distributed-system frameworks (NServiceBus and MassTransit) there's really no killer app for .NET, in my opinion.
The big selling point for .NET now is that it runs on Linux...which is not really a selling point in the grand scheme of things.
ASP.NET Core is an excellent and high-performance general purpose web framework.
Blazor is an excellent C# on the browser stack.
And MAUI will target React Native (native controls) and Cordova (Blazor on Maui) at the same time ... which is extremely powerful. But that is half a year out.
.NET has a lot to offer if you take individual app models of it. If you want to stick in one language, it is even a top contender.
Linux selling point is already gone. That is standard already for 5 years now.
