Grpc.AspNetCore.Web 2.46.0 Prefix Reserved

Grpc.AspNetCore.Web

Grpc.AspNetCore.Web provides middleware that enables ASP.NET Core gRPC services to accept gRPC-Web calls.

In Startup.cs:

public void ConfigureServices(IServiceCollection services)
{
    services.AddGrpc();
    services.AddGrpcWeb(o => o.GrpcWebEnabled = true);
}

public void Configure(IApplicationBuilder app)
{
    app.UseRouting();
    app.UseGrpcWeb();
    app.UseEndpoints(endpoints =>
    {
        endpoints.MapGrpcService<GreeterService>();
    });
}

gRPC-Web can be enabled for all gRPC services by setting GrpcWebOptions.GrpcWebEnabled = true, or enabled on individual services with EnableGrpcWeb():

app.UseEndpoints(endpoints =>
{
    endpoints.MapGrpcService<GreeterService>().EnableGrpcWeb();
});
