GZIP in .net core not working

Question

I'm attempting to add Gzip middleware to my ASP.net core app.

I have added the following package :

"Microsoft.AspNetCore.ResponseCompression": "1.0.0"

In my startup.cs for the Configure Services method I have the following :

public void ConfigureServices(IServiceCollection services) {     services.Configure<GzipCompressionProviderOptions>(options => options.Level = CompressionLevel.Fastest);     services.AddResponseCompression(options =>     {         options.Providers.Add<GzipCompressionProvider>();     });      services.AddMvc(); } 

In my Configure method I have the following :

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) {     loggerFactory.AddConsole(Configuration.GetSection("Logging"));     loggerFactory.AddDebug();      app.UseResponseCompression();     app.UseMvc(); } 

However when I try and load a page, it doesn't come through as Gzip compressed. I have used both a string response and outputting a view. The response headers in chrome look like :

I am on a windows machine developing in visual studio. When running the app I have tried just running from Visual Studio (Via F5), and also using the "dotnet run" command from command line. Neither output GZip compression.

To Enable GZIP in .net core 2.*
1. Install Microsoft.AspNetCore.ResponseCompression with Install-Package Microsoft.AspNetCore.ResponseCompression command or nuget package manager.
2. Add the following code into Startup.cs

public void Configure(IApplicationBuilder app, IHostingEnvironment env) {    app.UseResponseCompression();   app.UseMvc();  }  public void ConfigureServices(IServiceCollection services) {    // Configure Compression level   services.Configure<GzipCompressionProviderOptions>(options => options.Level = CompressionLevel.Fastest);    // Add Response compression services   services.AddResponseCompression(options =>   {       options.Providers.Add<GzipCompressionProvider>();       options.EnableForHttps = true;   });  }
