How to trust IIS Certificates for Development

 Type the following on a command line 

> dotnet dev-certs https --trust


If you're accessing the dev site from another computer or device, via an application, you can disable ssl certificate checking in the client app with...


HttpClientHandler handler = new HttpClientHandler();

handler.ServerCertificateCustomValidationCallback = ( message, cert, chain, errors ) => 

{

if(cert.Issuer.Equals("CN=localhost"))

                {

return true;

                }


return errors == System.Net.Security.SslPolicyErrors.None;

};


Notes about Android and Xamarin

Requires TLS 1.2

The default AndroidClientHandler supports TLS 1.2, but only for Android versions greater than 4.1

If an Android version is needed that is lower than 4.1, then we'll need to use the HttpClientHandler which supports TLS 1.0.  It is slower and increases the package size.


Notes about iOS and Xamarin

Requires TLS 1.2

The HttpClient uses NSUrlSession, this is the default and supports TLS 1.2

Alternatively, you'll need to use CFNetwork for older iOS versions

Tip to create an underline on a heading shorter than the heading itself

You can use a pseudo element with :before (or :after ): h1 { font - weight : 300 ; display : inline - block ; padding - bottom : 5px ; position : relative ; } h1 : before { content : "" ; position : absolute ; width : 50 %; height : 1px ; bottom : 0 ; left : 25 %; border - bottom : 1px solid red ; } http://jsfiddle.net/9e27b/ This is another solution that centers the heading, the problem here is that the underline gets shorter as the column gets shorter. h2 {   display: inline-block;   padding-bottom: 15px;   position: relative;   width: 100% ;   text-align: center; } h2:before{     content: "";     position: absolute;     width: 8%;     height: 1px;     bottom: 0;     left: 46%;     border-bottom: 1px solid red; }

The web.config no extension mime problem Lets Encrypt on IIS/Windows

  Tip when using LetsEncrypt in Windows - Feature Requests - Let's Encrypt Community Support In a paragraph, just use the web.config file to set the mime type, eg...  After trying to figure out why my Lets Encrypt failed to generate in Windows, and discovering that it's the no extension mime type problem, I wondered whether certbot could fill in the missing gap. All that is needed is the following web.config file to be placed in the same directory as the challenge <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <staticContent> <mimeMap fileExtension="." mimeType="text/xml" /> </staticContent> </system.webServer> </configuration> Because there's no mime type for files without an extension on IIS, IIS sends back a 404 when verification happens. The web.config file above sets the mime type. After I created the .well-known
