Latest #dotnetcore 3.0 runtime build just dropped the memory use of the #aspnetcore @TFBenchmarks benchmarks by half!  

There is now a minimal version of VS Code that can run in a browser that is available for development and testing.  

Some months ago a feature landed in Xamarin.Forms that seemed to truly polarize the Xamarin.Forms community: support for styling applications using CSS. Some argued that it was an unnecessary introduction to "Web" technology to the native development experience, and others that it simply isn't the right solution to the problem.  While I sympathize with the latter opinion and think there's plenty of room for some good debate on the right path forward, I count myself as part of a third camp: I think that CSS is a powerful (and frequently maligned) solution to the problem of styling native mobile applications.

In this article we are going to discuss how to insert, update and delete data into database using ASP.NET MVC 4.0. There is a Layout page and Data base script that we are going to use for this but we are not going to discuss much  how to create a Layout page and database script here in detail. 

HTTP Error 403.14 - Forbidden
The Web server is configured to not list the contents of this directory.
Most likely causes:

    A default document is not configured for the requested URL, and directory browsing is not enabled on the server.

Things you can try:

    If you do not want to enable directory browsing, ensure that a default document is configured and that the file exists.
    Enable directory browsing using IIS Manager.
        Open IIS Manager.
        In the Features view, double-click Directory Browsing.
        On the Directory Browsing page, in the Actions pane, click Enable.
    Verify that the configuration/system.webServer/directoryBrowse@enabled attribute is set to true in the site or application configuration file.

    .set('grant_type', "refresh_token")
    .set('refresh_token', refreshToken);

      headers: new HttpHeaders()

}

The key point is that even if you have a monster development machine with 128 processors, SSD drives and 1TB of memory, Visual Studio will only ever use 2 to 2.5GB of memory.
