What type of talks are you looking for?

We welcome topics that are relevant to the wider .NET community. We’d appreciate some link to a JetBrains product (but the talk should not necessarily be product focused, just for demos is fine).

Some areas we’re always interested in:

  • Architecture, clean code, patterns, DDD, defensive coding, …
  • F#, Fable, SAFE Stack, functional programming, …
  • Performance tuning, memory management, profiling, debugging, concurrency, benchmarking, logging, OpenTelemetry, …
  • Language-related! C#, F#, VB.NET, source generators, …
  • ASP.NET Core, Blazor, OpenAPI, gRPC, …
  • Avalonia, Uno Platform, cross-platform .NET, …
  • Databases, Entity Framework, Dapper, …
  • Testing and all of its flavours
  • Anything that does not fit the list above

Have a look at our 2022, 2021, 2020 and 2019 editions to get an idea.

Not sure if your talk idea will fit? Reach out to and we can discuss.

More information is available on our Call for Speakers page. Thanks in advance for submitting your talks!
