NetCoreUsefullEndpoints-2–MVP

So let’s start the implementation for user / error / environment.

The only difficulty resides in the fact that IEndpointRouteBuilder is not defined into a usual library, but the dll csproj must contain

	<ItemGroup>
		<FrameworkReference Include="Microsoft.AspNetCore.App" />
    </ItemGroup>

Otherwise , it is work as usual. For example, for seeing a user

 public static void MapUser(this IEndpointRouteBuilder route)
{
    ArgumentNullException.ThrowIfNull(route);
    route.MapGet("api/usefull/user/", (HttpContext httpContext) =>
    {
        return Results.Ok(httpContext.User?.Identity?.Name);
    }).RequiresAuthorization();
}

More difficult was for Environment – that is a Static class. Hopefully, there is a NUGET for this – https://www.nuget.org/packages/rscg_static – that allows to generate an interface from a static class. So I have added this

	<ItemGroup>
		<FrameworkReference Include="Microsoft.AspNetCore.App" />
    </ItemGroup>

And code for generating the interface

public partial class Helper
{
    public partial ISystem_Environment FromStaticEnvironment();

}

So, when I want to get the values from Environment, I use this

public static void MapUsefullEnvironment(this IEndpointRouteBuilder route, string? corsPolicy = null, string[]? authorization = null)
{
    ArgumentNullException.ThrowIfNull(route);

    var rh=route.MapGet("api/usefull/environment/", (HttpContext httpContext) =>
    {
        return Results.Ok(new Helper().FromStaticEnvironment());
    });
    rh.AddDefault(corsPolicy, authorization);

}
