.NET MAUI Environment variable

Question

Is there a way how to find out that the current environment in .NET MAUI is development ? Because before in my Blazor WASM I did just: builder.HostEnvironment.IsDevelopment()

But in MauiAppBuilder I dont see any environment property.

Answer 1

I approached it a little bit different. I have created MobileHostEnvironment:

internal sealed class MobileHostEnvironment : IHostEnvironment
{
    public string EnvironmentName { get; set; } = Environments.Development;
    public string ApplicationName { get => throw new NotImplementedException(); set => throw new NotImplementedException(); }
    public string ContentRootPath { get => throw new NotImplementedException(); set => throw new NotImplementedException(); }
    public IFileProvider ContentRootFileProvider { get => throw new NotImplementedException(); set => throw new NotImplementedException(); }
}

then at the beginning of MauiProgram.cs I declare and initialize it like:

private static readonly MobileHostEnvironment _mobileHostEnvironment = new()
{
    EnvironmentName = Environments.Production
};

with a reference to using Microsoft.Extensions.Hosting; and before service registering I have:

#if DEBUG
        _mobileHostEnvironment.EnvironmentName = Environments.Development;
#endif

So that way app in debug is always Development and released one is always Production.

Ofc you can improve this flow by registering it into dependency container.

What I usually do for this is I use the "if" directive.

For instance, if I want to set a different value to var in release than in debug I would do something like below:

#if DEBUG
var a = "debug";
#elif RELEASE
var a = "release"
#endif
