WebWindowNetCore 10.0.0-beta-8

WebWindowNetCore

Notes for Developers

Developing for Windows

In the project file WebWindowNetCoe.fsproj replace the following line

<TargetFrameworks>net8.0;net8.0-windows</TargetFrameworks>

with

<TargetFrameworks>net8.0-windows</TargetFrameworks>

Don't forget to replace it to the original value before publishing a new nuget version

new

• WebWindowNetCore.Window and .Linux to this project
• Publish WebwindowNetCore only from Windows
• Test lionux version in Linux with if Windows Windows code and Windows.Forms.dlls

A Webview Application for Windows and Linux similar to Electron. It uses a functional builder pattern to set up the application. It has an integrted Asp.NET (Kestrel) server which can be used to host the app and to communicate between the C# application and the web app:

• you can call via javascript fetch from the web app (json input and output)
• The C# app can send SSE events to the web app

Prerequisites for Linux

sudo apt install libgtk-4-dev !!!No!!!
` 

WebWindowNetCore is the base Nuget packege, you need one more Nuget packages for every to supporting Operating system:

| Windows  | Linux  |
|---|---|
| WebWindowNetCore.Window  |  WebWindowNetCore.Linux |

## Functional builder setup in the C# application
There is a builder pattern to setup the application (```WebView.Create```):

WebView .Create() .InitialBounds(600, 800) .Title("WebView Test") .ResourceIcon("icon") .SaveBounds() .Url($"file://{Directory.GetCurrentDirectory()}/webroot/index.html") #if DEBUG
.DebuggingEnabled() #endif
.Build() .Run();

### Setup integrated kestrel server

The integrated Asp.NET kestrel server also uses a builder pattern (```ConfigureHttp```)

WebView .Create() .InitialBounds(600, 800) .Title("WebView Test") .ResourceIcon("icon") .SaveBounds() .ConfigureHttp(http ⇒ http .ResourceWebroot("webroot", "/web") .UseJsonPost<Cmd1Param, Cmd1Result>("request/cmd1", JsonRequest1) .UseJsonPost<Cmd2Param, Cmd2Result>("request/cmd2", JsonRequest2) .UseSse("sse/test", sseEventSource) .Build()) #if DEBUG
.DebuggingEnabled() #endif
.Build() .Run("de.uriegel.Commander");

The default (local) port is 20000. It can be adapted.

### Serving web app files from resource

It is possible to serve the web app via the integrated kestrel server, when the web app files are included as C# resources. You have to specify the resource root, under which the resource files are saved.

Please refer to the sample App

### How to setup .NET project:

<PropertyGroup> <IsWindows Condition="'$([System.Runtime.InteropServices.RuntimeInformation]::IsOSPlatform($([System.Runtime.InteropServices.OSPlatform]::Windows)))' == 'true'">true</IsWindows> <IsOSX Condition="'$([System.Runtime.InteropServices.RuntimeInformation]::IsOSPlatform($([System.Runtime.InteropServices.OSPlatform]::OSX)))' == 'true'">true</IsOSX> <IsLinux Condition="'$([System.Runtime.InteropServices.RuntimeInformation]::IsOSPlatform($([System.Runtime.InteropServices.OSPlatform]::Linux)))' == 'true'">true</IsLinux>
</PropertyGroup>

<PropertyGroup Condition="'$(IsWindows)'=='true'"> <OutputType>WinExe</OutputType> <TargetFramework>net6.0-windows</TargetFramework> <RuntimeIdentifier>win-x64</RuntimeIdentifier> </PropertyGroup>

<PropertyGroup Condition="'$(IsLinux)'=='true'"> <OutputType>Exe</OutputType> <TargetFramework>net6.0</TargetFramework> <RuntimeIdentifier>linux-x64</RuntimeIdentifier> </PropertyGroup>

<ItemGroup Condition="'$(IsWindows)'=='true'"> <PackageReference Include="WebWindowNetCore.Windows" Version="..*" /> </ItemGroup>

<ItemGroup Condition="'$(IsLinux)'=='true'"> <PackageReference Include="WebWindowNetCore.Linux" Version="..*" /> </ItemGroup>
