What is WebApiClientGen for ASP.NET and Angular?

Code generator that turns your ASP.NET Core DTOs and validations into Angular reactive forms and TypeScript clients.

Does WebApiClientGen handle custom .NET validators?

Built-ins yes (Required, Range, Email). Custom? Limited — extend the templates yourself.

Can I use WebApiClientGen with Angular 17+?

Yes, outputs modern reactive forms. Test your Angular version's FormControl compatibility.
