Modern IDEs are packed with powerful features, but discovering and using them effectively is challenging. 👀
Most developers remember only a few shortcuts – what if your IDE helped you discover its actions like it helps you write code, with completion? ⚡ Learn more in the blog below:

Damn, it is hard to believe, but Java compiles the `switch` over the `String` values by using the runtime-provided `hashCode()` impl. Meaning it is not possible to change the `String.hashCode` impl w/o recompiling all the Java programs.

There was an old ruler called Ozzy
Who built a big statue just 'cos he
Thought he would never
Not be known for ever
And now it's two legs in a cozzy
Who built a big statue just 'cos he
Thought he would never
Not be known for ever
And now it's two legs in a cozzy
Oh I wish I’d looked after me works
And not left me legs buried in dirt
Look on them there
And ye mighty, despair
Oh I wish I’d looked after me works
And not left me legs buried in dirt
Look on them there

We are getting closer to the release of Resharper 2025.3 , so I ran some performance tests to see how much we improved compared to 2025.2.
For this iteration, I focused my effort mainly on the huge Datadog.Trace solution, available on the DataDog/dd-trace-dotnet repository.
