Expert Insights

The .NET question is rarely about the technology any more. Both platforms are mature, both run everywhere, and either will do the job. What decides it is the estate around the application: the identity provider, the database, the reporting stack, the team that will own it after we hand it over. Where that is already Microsoft, .NET stops being a choice and starts being the path of least resistance, and the build is faster for it.
Anand Mahajan CEO, Sphinx Solutions

.NET vs. Java

.NET or Java: Which to Build Your Back End On

Both are mature, both run everywhere that matters, and both will still be here in ten years. What separates them is the ecosystem around them and the one your organisation already runs.

Factor .NET Java / JVM
Maintained by Microsoft. One vendor ships the runtime, the SDK, the IDE and the cloud it deploys to. Oracle ships a JDK, and so do Eclipse Adoptium, Amazon, Azul and Red Hat. You choose a distribution.
Main language C#, with F# and Visual Basic on the same runtime. Java, with Kotlin, Scala and Groovy on the same runtime.
Where it runs Windows, Linux and macOS since .NET Core. The older .NET Framework is Windows only. Anywhere with a JVM, which has been every mainstream server platform for decades.
Licence Open source under the MIT licence, with Microsoft support terms for LTS releases. Depends on the distribution. OpenJDK builds are free; Oracle\x27s own JDK has commercial terms.
Release cadence One major release a year, with every second one on long-term support. Two releases a year, with an LTS every two years.
Strongest fit Teams already on Microsoft tooling, Azure, SQL Server or Dynamics, and Windows desktop work. Large existing Java estates, Android back ends, and the Hadoop and Kafka data ecosystem.
Talent pool Deep in enterprise IT, and the default in organisations that standardised on Microsoft. The larger pool overall, and the one most computer science courses teach first.
