Yes this 100%. Community ecosystem is a joke on C# compared to Java. Take for example lucene. I just used version 3.03 in a C# project because the port hasn't been updated in years. Version 6.x is the current one.

We also needed to use Redis in C# and the client is unstable. Nothing we can do about it besides catch the exceptions and randomly reconnect when it happens. Are we losing some data? Probably.

Even if the open source community embraces C# it will take 10 years before the offerings are comparable to Java. And for what? C# is nearly identical to Java in design and performance, it just has slightly prettier syntax
