ASP.NET Core 6 how to access IWebHostEnvironment before builder.Build() in Program.cs

Question

I want to use Environment.IsDevelopment() before builder.Build() in Program.cs. How should I do that?

 var builder = WebApplication.CreateBuilder(args);
 //Code: reach environment
 var app = builder.Build();

Answer 1

You can access which environment you are currently running as by using:

builder.Environment.IsDevelopment()

Prior to the application being built at this point:

var app = builder.Build();

After this code has run you would use:

app.Environment.IsDevelopment()
