Access Web.config from another Project.

By -
Many of our .Net web app solutions have multiple class library projects and in those projects we want to access various app settings in a central web.config housed in the web app project.

You will find that simply accessing the Configuration Manager in a class library will not compile.


Huh? But it works just fine in my web project. Even ReSharper can't help me here. That's because the assembly required for the Configuration Manager doesn't ship with Class Library projects out of the box.

To fix the problem add the System.Configuration assembly to your project.


If you have ReSharper, it will now be able to help you by automatically importing the namespace. Otherwise, just add it yourself manually.


Hope this helps!

IIS Express Client Certificates

By -
We recently had to investigate how to  CAC -enable a web application, one of the challenges was setting up a proper development environment to prototype & test code changes before deploying to other environments. STEP 1  - You need to have a client certificate installed on your development machine. Assuming you don't have a readily available CAC or Smart Card, you can either  create a self-signed certificate  OR for this example we just used a  corporate outlook email client certificate (used to sign & encrypt emails).   Note : The certificate should be available in your web browser. For IE go to  Internet Options > Content > Certificates  to view all your certificates. In Chrome, go to  Settings > Show advanced settings > HTTPS/SSL > Manage certificates . STEP 2  - Using Visual Studio, create a default ASP.NET MVC 5 web application. STEP 3  - Enable SSL for your project. In Visual Studio, hit  F4...

ASP.NET Identity Remember Me

By -
ASP.NET Identity comes with a built-in Remember Me feature on the Login form, it's supposed to keep a user logged in (via an authentication cookie) for a predetermined period of time set via your code settings. However it sometimes might not work as expected and users will have to frequently log in which will cause quite a bit of frustration. Your first reaction is to modify your code then test / rinse / repeat and possibly still see the same unsuccessful results ... did you also check your website's IIS settings? Code Settings Let's first take a look at the Code configuration settings. If you create a new default MVC 5.x application in Visual Studio (with Authentication set to  Individual User Accounts ) the following code is generated (in  /App_Start/Startup.Auth.cs ): app.UseCookieAuthentication(new CookieAuthenticationOptions { AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie, LoginPath = new PathString("/Account/Login"), Provi...

ASP.NET MVC - How to enable/disable CaC/Client Certificate authentication per area or route.

By -
Image
Use Case Typically, when you enable CaC/Client Certificates on a web app you enable it for the entire app. But what if you wanted to disable it for certain sections of the site. For example, an API controller, or a specific Area that hosts pages that can be publicly viewed. Luckily, it's very easy to make this happen. I'll walk through an example that requires CaC authentication for the base app but does not require it to make requests on an API controller, which will use leverage the HTTP Authentication header for auth.  1. Modify the web.config To require client certs for the base app, add this snippet inside the <system.webServer> tag. <!-- Access for the Base App --> <security> <access sslFlags="Ssl, SslNegotiateCert, SslRequireCert" /> </security> Now we can selectively disable client certs for specific sections of the app. In this case, I am disabling it for all routes starting with /api/v1 ....
