Publish an ASP.NET website without roslyn folder

If you create a ASP.ENT website using Visual Studio 2015 or higher and .NET Framework 4.5.2, it by default uses Roslyn which is a set of open-source compilers and code analysis APIs for C# and Visual Basic. Publishing this would also include “roslyn” folder in bin directory containing a bunch of libraries and exe files which creates issues if you are using a shared hosting service as normally shared hosting do not run under full trust. We can simply remove this by going to Tools -> NuGet Package Manager -> Manager NuGet Packages for Solution -> Uninstall following packages Microsoft.CodeDom.Providers.DotNetCompilerPlatform Microsoft.Net.Compilers Check web.config and make sure the following section was removed by the NuGet package uninstall. If it did not get removed for any reason, then clean it up manually <system.codedom> <compilers> <compiler language=”c#;cs;csharp” extension=”.cs” type=”Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35″ warningLevel=”4″ compilerOptions=”/langversion:6 /nowarn:1659;1699;1701″/> <compiler language=”vb;vbs;visualbasic;vbscript” extension=”.vb” type=”Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35″ warningLevel=”4″ compilerOptions=”/langversion:14[…]

Force Windows Store App to Full Screen Mode

In order to launch windows store app to full screen mode, check out the code here. Once app is launched in full screen mode, it can be resized by user by using the resize option which is available in all app windows and can not be removed. For windows pc, we can capture window resize event and try to enter full screen again which in effect doesn’t let user resize the application window. The java script code for achieving this: var page = WinJS.UI.Pages.define(“/index.html”, { ready: function (element, options) { // Add event for window resize event window.addEventListener(“resize”, onResizeView); } }); function onResizeView() { // Whenever window is resized, enter it to full screen mode var ViewManagement = Windows.UI.ViewManagement; var ApplicationView = ViewManagement.ApplicationView; var view = ApplicationView.getForCurrentView(); view.tryEnterFullScreenMode(); }  

Launch External Url in Browser from Windows Store App

The java script code for achieving this: // Create a Uri object from a URI string var uri = new Windows.Foundation.Uri(“http://test.com”); var options = new Windows.System.LauncherOptions(); // Launch the URI with a warning prompt options.treatAsUntrusted = true; // Launch the URI Windows.System.Launcher.launchUriAsync(uri, options).then( function (success) { if (success) { // URI launched } else { // URI launch failed } });  

Quick Tip

Convert C# Object to JSON and create object from JSON string

Json.Net is the preferred way to go about it because of performance gain it gets compared to JavascriptSerializer. Download and install Newtonsoft.Json using Nuget Now in order to create Json for an object simply use SerializeObject method as following Product product = new Product(); product.Name = “Apple”; product.Expiry = new DateTime(2008, 12, 28); product.Sizes = new string[] { “Small” }; string json = JsonConvert.SerializeObject(product); // { // “Name”: “Apple”, // “Expiry”: “2008-12-28T00:00:00”, // “Sizes”: [ // “Small” // ] // } In order to convert Json to the object use DeserializeObject method as following string json = @”{ ‘Name’: ‘Bad Boys’, ‘ReleaseDate’: ‘1995-4-7T00:00:00’, ‘Genres’: [ ‘Action’, ‘Comedy’ ] }”; Movie m = JsonConvert.DeserializeObject<Movie>(json); string name = m.Name; // Bad Boys  

Manage Amazon Promotions in ASP.NET Application

If you are into affiliate marketing then you must be getting promo codes from your partners which are promoted on various platforms. For ex, Amazon publishes promo codes for Associates which can then be pormoted by the Associates and they get a cut from the sales. Its a nice way to boost conversion and earn commission. Associates share the link to temporary promotion pages which is tagged with their affiliate id. These promotions run for a short duration and need to be managed more frequently by adding/removing them from your site almost on a daily basis so it makes sense to have a small database at your end which you can use to manage it at your end and it can also take care of the promotions which have ended. If a promotion has ended, Amazon takes you to the deals page when a promotion link is clicked but it makes[…]
