Azure returning a 404 for woff files

This is actually a configuration error, as described here

http://www.codepal.co.uk/show/WOFF_files_return_404_in_Azure_Web_Sites

The solution was to add the following to the web.config:


  <system.webServer>
    <staticContent>
      <mimeMap fileExtension="woff" mimeType="application/font-woff" />
      <mimeMap fileExtension="woff2" mimeType="application/font-woff" /> 

    </staticContent>

OpenVPN not changing my IP address

When I installed the OpenVPN client and connected to a VPN it changed my IP address correctly. However, subsequent times it didn't change it. It turned out I had to run the application as an administrator, and that was it.

How to return a 401 status code using ASP.NET MVC 5 and OWIN

This time I was trying to force users to the login page after an Ajax request failed because of an expired session. I was getting something like this in the response:

X-Responded-JSON: {"status":401,"headers":...
  
I investigated a little and turned out you have to add this code to your Startup.Auth.cs file:

Provider = new CookieAuthenticationProvider

{

  OnApplyRedirect = ctx =>

  {

    if (!IsAjaxRequest(ctx.Request))

    {

       ctx.Response.Redirect(ctx.RedirectUri);

    }

  }

}


Also, in your filter I suggest you do something like this:


if (filterContext.HttpContext.Request.IsAjaxRequest())
{
filterContext.HttpContext.Items["RequestWasNotAuthorized"] = true;
filterContext.HttpContext.Response.StatusCode = 401;
filterContext.HttpContext.Response.End();
filterContext.Result = new HttpUnauthorizedResult();
}

And then handle it in JavaScript like this:

$(document).ajaxError(function (xhr, props) {
if (props.status === 401) {
location.reload();
}
});

A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - The handle is invalid.)

The solution is simple, just reset IIS. If that doesn't work, this SO question will help

Run Visual Studio as an administrator all the time

Why is it that right-clicking the Visual Studio icon and then clicking Visual studio opens the application as an administrator (after you configure it this way in the properties window) but right-clicking the Visual Studio icon and then clicking a project doesn't? In Windows 8 and 10 you have to follow a few more steps as defined here (http://stackoverflow.com/questions/9654833/how-to-run-visual-studio-as-administrator-by-default)

Right-click devenv.exe and select "Troubleshoot compatibility".

1. select "Troubleshoot program"
2. check "The program requires additional permissions" click "Next", click "Test the program..."
3. wait for the program to launch
4. click "Next"
5. select "Yes, save these settings for this program"
6. click "Close"

Entity Framework - Store update, insert, or delete statement affected an unexpected number of rows (0)

This error can have several causes, in my case it was that I had forgotten to create the PK and identity columns in a table. More complex causes can be found here http://stackoverflow.com/questions/1836173/entity-framework-store-update-insert-or-delete-statement-affected-an-unexpec

PowerShell - "AuthorizationManager check failed" from Octopus Deploy

I came across this error when trying to run Import-Module in an Octopus Deploy PowerShell script. This script was in the source code. What I end up doing was taking out Import-Module into its own Octopus Deploy step "Run a Script".

This article also thoroughly explain the reason for the error http://tgnp.me/2011/09/powershell-authorizationmanager-check-failed-resolution/

In the process, I also learned that Octopus Deploy changes the execution policy of the Powershell process to unrestricted.
