Hello Team, I started familiarizing containerization concepts using Docker in .NET Core in the event that our team will embrace the application of containerization to our certain projects in the near future. When I installed the Docker desktop, it prompted an error "Docker Desktop Requires A Newer WSL Kernel Version Issue. Update the WSL kernel by running "wsl --update" or follow instructions at https://docs.microsoft.com/windows/wsl/wsl2-kernel." The fix to this issue is either running the "wsl --update" command similar to the screenshot below. Or download and install "wsl_update_x64" package from here Linux Kernel Update Package Cheers!

Hello, In one of the parser that I made, I need to extract the node name which is in a self closing XML tag as part of the requirement for the output. In order to do that, you need to combine a positive lookbehind for the lesser than symbol (?<=<) and positive lookahead for the forward slash and greater than symbol (?=/>). And then perform a greedy search in between those groups. The complete pattern for that is presented on the code snippet below. var NodeValue = Regex.Match(lstTempNodes[i], @"(?<=<)(.*)(?=/>)" ).Value.Trim(); Here's the pattern matching of several self-closing XML tags.

Hello, Most of us C# developers are working on Dictionaries to store multiple sets of data with unique keys. And in times that we need to modify our logic with the Dictionary object involved, we normally do that using looping construct. Given a simple Dictionary object below with int as key and string as value. Dictionary< int , string > styledLines = new Dictionary< int , string >(); We may thought that looping through this object with the code presented below may work. However, when running your app, this will cause a "Collection was modified; enumeration operation may not execute" issue. It's because we are using the collection's key directly. foreach ( var kvp in styledLines) { styledLines[kvp.key] = $ "Series# {seriesNum} "; } To fix that we have a couple of options. Given that our key is an integer type with values in sequential order such as 0...1000, we could use for loop to change the values such as below. var startI

Hello Everyone! In relation to the previous post on updating the serialization and deserialization using BinaryFormatter class to NewtonSoft's JsonSerializer, we also need to change the Binder functionality using NewtonSoft. The class below inherits the SerializationBinder and overrides the BindToType() function. sealed class HELPERSCustomBinder : SerializationBinder { public override Type BindToType( string assemblyName, string typeName) { if (!typeName.ToUpper().Contains( "SYSTEM.STRING" )) { throw new SerializationException( "Only List<string> is allowed" ); } return Assembly.Load(assemblyName).GetType(typeName); } } The class above will then be assigned to the Binder property of BinaryFormatter as shown from the code snippet below. public static T BuildFromSerializedBuffer<T>( byte [] buffer) where T : new () { MemoryStream MS; BinaryFormatter BF; T rtn; rtn = default (T); try { using (M

Good evening! Part of the migration of our parts cataloging WPF application to .NET 7 was to investigate obsolete code and refactor that to something acceptable and maintainable in the future. One of which that needs to be addressed is the BinaryFormatter class used for serialization and deserialization. Searching thru the internet presents tons of options but since the application has already a Newtonsoft.Json package, we decided to use it's serialization instead. So to proceed with, below are the sample serialization and deserialization functions that incorporates the BinaryFormatter class and converted to NewtonSoft.Json.JsonSerializer. Below is a function using BinaryFormatter serialization. public static byte [] GetSerializedBuffer<T>(T itemToSerialize) { byte [] rtn; MemoryStream MS; BinaryFormatter BF; if (! typeof (T).IsSerializable && !( typeof (ISerializable).IsAssignableFrom( typeof (T)))) throw new InvalidOperationException( "A ser

Good day! Following a tutorial on Xamarin.Forms, I encountered this issue namely " adb is not recognized as an internal or external command " when running adb commands in command prompt. After doing some research for answers to this problem, I came up with the steps to make it work. First is to locate the path of the adb application which can be found in android-sdk->platform-tools folder Next is to go to System Properties and open Environment Variables form. Under System variables, locate the Path entry and click the Edit button. Copy the folder path of the adb.exe application and add it as a new entry to the System variable Path. Click Ok and restart your computer. The adb command should work as expected.

Hello, When running your WPF application thru Visual Studio, you may find a UI toolbar that is useful for checking the Adorner or Visual Tree of the control such as below. However, if you want to remove that toolbar, go to Tools menu -> Options -> Debugging. Then uncheck " Enable in-app toolbar ". Click Ok. Run the application again and you will notice that the UI toolbar disappear.

Good evening! I had an issue when opening PDF files using Process.Start() which is called in a ShowFile() method of the project. The code which isn't working is shown below. System.Diagnostics.Process.Start(Path.Combine(myDocumentsPath, fileName)); The solution for that is to pass a ProcessStartInfo() object in the Start() parameter. And then set UseShellExecute property of the ProcessStartInfo object to true. The modified code that is working is shown below. System.Diagnostics.Process.Start( new ProcessStartInfo(Path.Combine(myDocumentsPath, fileName)) { UseShellExecute = true }); Output

Good evening! In this post, I will demonstrate on how to pass a view model or an element as ConverterParameter value in XAML. This methodology is widely used by developers if you need to retrieve certain values or properties from a view model object or element. To send the view model data context as ConverterParameter value, reference the view model class in the data context node of your form or user control. <UserControl d:DesignHeight= "450" d:DesignWidth= "800" > <UserControl.DataContext> <localmain:ConfigurationResourceManagerViewModel x:Name= "vmResourceManager" /> </UserControl.DataContext> </UserControl> In your element as to where the ConverterParameter is, set it's value with the view model name. In the example snippet below, the ConverterParameter is used in the ComboBox SelectedItem property with a reference to the view model object. <DataGridTemplateColumn Header= "Resource

Hello and Happy Easter! A while ago I was downloading some Xamarin Forms projects from Github for testing and research purposes. Upon running the projects, it won't show on the Android emulator and in the Visual Studio IDE, a notification shows that the project was skipped in deployment with a detailed statement like "Project Not Selected To Build For This Solution Configuration" . I found the solution which is to right click on the Solution of the project -> Select Configuration Manager. If you notice, the Deploy checkbox is unchecked. Changing the state to checked solved the issue. I can now run the projects using the Android emulator. Cheers!
