On .NET

In last week’s episode, we’re speaking with Beth Massi to celebrate .NET’s 15th anniversary:

This week, Eric Mellino will be on the show to demo CrazyCore, a game engine written on .NET Core. We’ll stream live on Channel 9. We’ll take questions on Gitter’s dotnet/home channel and on Twitter. Please use the #onnet tag. It’s OK to start sending us questions in advance if you can’t do it live during the shows.

NeinLinq provides helpful extensions for using LINQ providers such as Entity Framework that support only a subset of .NET functions, reusing functions, rewriting queries, even making them null-safe, and building dynamic queries using translatable predicates and selectors.

Here’s an example of a Linq expression that uses a custom function that would otherwise get rejected as not translatable:
