WPF .NET Core ToolKit

This Toolkit let you rapidly add a new small test by adding a new UserControl and connect it to a new button on main window.

Like this:

Summary

Personal logger
Back to basics of Logs
Add an appsettings.json file
File Logger Provider
Create Style for toolbar
Using Git Submodule

UserControl1

Use Logger Tool

UserControl2

Demonstrate the use of Dependency Property
Show Style.Triggers

UserControlLog

.NET Core 6.0 way of produce Logs using .NET Core standard ILogger and ILoggerFactory

UseAppSettings

Read application configuration in appsettings.json file

Personal logger

It could be intresting to have it's own logger system at a time where everyone says to do not reinvent the wheel, while doing it. Sometimes I could found log4net diffcult to install and configure.

Tools/Logger

Loggin is a more tough subject than we can think, especially since log4net has become a gas factory.

Log message into severals, file, console, trace, windows easily add your own method. Manage level of severity.

It's an exemple of using delegate function System.Action

    public static Action<string> WriteMessage;

Configuration is done in control after InitializeComponent :

    Logger.WriteMessage += LoggingMethods.LogToConsole; 
    Logger.WriteMessage += LoggingMethods.LogToTrace;
    Logger.LogLevel = Severity.Verbose; // by default set to Warning

path to the log file :
- WpfAppCore1\bin\Debug\netcoreapp3.1\log.txt

The use of this component have been demonstrated in a Blazor project: MyBlazorServerApp

ToDo

complete logfile name with the date of the day
format the login massage
make user to specify log file path

Back to basics of Logs

While I'm working on new apps, log is style a tricky subject. If I want to enhance my personnal logger I'll have some work. I saw something like adjust log level in appsettings could make you see internal core library messages and this is cool.

- This is one for .NET Core particulary Non-host console app hard to find but this code is not usefull teel appsettins.json file is present.

While I'm working on loggin features I found intresting to make logs in the .NET Core standard way.

This is the aim of UserControlLog plus some little things like add Program.cs file in the project

    <PackageReference Include="Microsoft.Extensions.Hosting" Version="8.0.0-preview.2.23128.3" />
    <PackageReference Include="Microsoft.Extensions.Logging" Version="8.0.0-preview.2.23128.3" />

Add an appsettings.json file

I'm surprise that default template WPF application are NOT with an an appsettings.json file ?! While WPF application create by TemplateSutio had one.

So add by hand an appsettings.json

Reference

The aim of adding an appsettings.json is to configure Log level.

Once the appsettings.jso file is here the following config will make logs at Trace level :

    "Debug": {
        "LogLevel": {
        "Default": "Trace",
        "Microsoft": "Trace",
        "Microsoft.Hosting": "Trace"
        }
    }

⚠️ If you change setting in appsettings.json, to be apply choose "Generate solution" for the appsettnigs.json file to be copied in directory:

WpfAppCore1\bin\Debug\net6.0-windows

While you're in Debug mode. Don't forget to have, in your .csproj :

    <ItemGroup>
        <None Update="appsettings.json">
	        <CopyToOutputDirectory>Always</CopyToOutputDirectory>
        </None>
    </ItemGroup>

File Logger Provider

All this is to use or create a FileLoggerProvider through the ILogginBuilder to write logs in a file without using third party provider wich are to complex to configure.

Develop it's own personal FileLoggin, like in the project's first part, is not sustainable.

This project now integrate a FileLogger that cames from tbebekis with just a small adaptation to display the log file.

GitHub - tbebekis - AspNetCore-CustomLoggingProvider

Add a TextBloc to display the log file:

That's the result the final result snif ;) that's what I wanted to do a console to display logs that are in a log file. This can be very useful for debugging in dantesque conditions.

Create Style for Toolbar

It's needed to add a Style for ToolBar Text

⚠️ Trying to create Style in <Application.Resources> create an exception in MainWindow InitializeComponent();

Style must be created in <Window.Resources>
