How to set ASP.NET 5 environment variables on production environment

In Visual Studio 2015 you set the following variable in project properties: ASPNET_ENV. If you set it to development then you can use:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseErrorPage();
    }
 }

IsDevelopment method will check ASPNET_ENV environment variable. Now this is all good on development while you are in Visual Studio 2015. When you publish the web application to IIS on a production server how can you set the value for ASPNET_ENV?

My server is Windows Server 2012

If you are using IIS to host your application, it's possible to set the environment variables in your web.configfile like this:

<aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false">
    <environmentVariables>
        <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="QA" />
        <environmentVariable name="AnotherVariable" value="My Value" />
    </environmentVariables>
</aspNetCore>
