Luckily a fix was already available. I updated to the latest Automapper version (12.0.1 at the moment of writing) and the issue disappeared.  

We decided to use Qt for our next Geospatial Intelligence Desktop App, but the .NET Core performance was close to Qt and both easily outperformed the JavaFX prototype. So, we are going to use .NET Core for our Geospatial Intelligence Services backend.

J (J language) is a high-level, general-purpose, high-performance programming language. J is portable and runs on 32/64-bit Windows/Linux/Mac as well as iOS, Android, and other platforms. J source (required only if Jsoftware binaries don't meet your requirements) is available under both commercial and GPL 3 license. J systems can be installed and distributed for free.

J systems have:

• an integrated development environment
• standard libraries, utilities, and packages
• console, browser, and Qt front ends
• interfaces with other programming languages and applications
• integrated graphics
• memory mapped files for high performance data applications
• Jd 

.NET Core is clearly where Microsoft is investing most of its effort right now and while it's taken a while, I think MS is proving that they are serious in making .NET the best platform it can be 

What’s new?

Here’s a sampling of the great new features and improvements in ASP.NET Core for .NET 7:

• Servers and runtime
  • Rating limiting: Limit the rate of handled requests using flexible endpoint configuration and policies.
  • Output caching: Configure output caching to reduce to more efficiently handle request.
  • Request decompression: Accept requests with compressed content.
  • HTTP/3: Built-in support for HTTP/3, the latest HTTP version based on the new QUIC multiplexed transport protocol.
  • WebSockets over HTTP/2: Use WebSockets over HTTP/2 connections.
  • WebTransport (experimental): Create streams and data grams over HTTP/3 with experimental support for WebTransport.
• Minimal APIs
  • Endpoint filters: Use endpoint filters to run cross-cutting code before or after a route handler.
  • Typed results: Return strongly typed results from minimal APIs.
  • Route groups: Organize groups of endpoints with a common prefix
• gRPC
  • JSON transcoding: Expand the reach of your gRPC services by also exposing them as JSON-based APIs
  • OpenAPI with JSON transcoding (experimenal): Use experimental support for generating OpenAPI specs for your gRPC JSON transcoded services.
  • gRPC health checks: Report and check the health of gRPC server apps.
  • gRPC client AddCallCredentials : Create clients that send authorized requests using bearer tokens.
• SignalR
  • Client results: Return client results to the server in response to requests from the server.
• MVC
  • Nullable view and page models: Nullable page and view models are now supported to improve the experience when using null state checking.
• Blazor
  • Custom elements: Build standard HTML custom elements with Blazor to integrate Blazor components with any JavaScript-based app.
  • Handle location changing events: Intercept location changing events to create custom user experiences when navigating.
  • Bind after/get/set modifiers: Run async logic after data binding and independently control how data binding gets and sets the data.
  • Dynamic authentication requests: Create dynamic authentication requests at runtime with custom parameters to handle advanced authentication scenarios in Blazor WebAssembly apps.
  • Improved JavaScript interop on WebAssembly: Optimize JavaScript interop call when running on WebAssembly using the new [JSImport]/[JSExport] support.
  • WebAssembly SIMD & exception handling: Improve performance with .NET WebAssembly ahead-of-time (AOT) compilation using WebAssembly SIMD and exception handling support.

Announcing the new version of Microsoft To Do—we’ve come a long way!  

With a great pleasure and great relief OpenCV team finally announces OpenCV 3.0 gold release, the most functional and the fastest OpenCV ever. And yet it’s very stable too – all the thousands of tests that we created during the project + many new tests pass successfully on Windows, Linux and Mac, x64 and ARM.
