Depends where. In the startup world? Absolutely. In tech in general? No - if anything its preferred. As a former .NET developer myself, the stigma isn't wholly unjustified. I've met more .NET developers that don't know what's going on underneath the libraries they are using than I have elsewhere - for example, using the Entity Framework but barely knowing SQL. The Microsoft certification process ensures that developers know how to make the same kind of corporate apps over and over, but don't necessarily understand the basics. There are a great many talented developers that aren't like that, though. And there is a lot to like about C# - I hope more people use it now that it's being open sourced.
