AppServiceDemo - React Native for Windows

This sample showcases the usage of React Native for Windows to interact with the Win32 ecosystem using App Services. This sample is documented in the following article.

It currently targets React Native Windows 0.64.

Setup

First, make sure you've met the React Native Windows System Requirements.

Then, within this folder, install the application's dependencies. If you have yarn installed:

yarn install

Otherwise, you can just use npm:

npm install

Run

Since this scenario is using a special configuration, you can't build and run the project using the CLI, but you have to take the following steps:

  1. Open with Visual Studio the solution included in the windows folder.

  2. Right click on the appservicedemo.Package project and choose Set as startup project.

  3. From the Configuration Manager dropdown, make sure you're building for the right CPU architecture (x86 or x64).

  4. Right click on the appservicedemo.Package project and choose Deploy.

    Due to an existing bug in React Native for Windows, you might hit a compilation issue with a similar error:

    Error Task 'AddProjectMetadata' failed. The expression "[MSBuild]::MakeRelative(C:\ReactCSharp, *Undefined*)" cannot be evaluated. Illegal characters in path. C:\ReactCSharp\node_modules\react-native-windows\PropertySheets\Autolink.props
ReactCSharp.Package C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\MSBuild\Microsoft\DesktopBridge\Microsoft.DesktopBridge.targets 408 
Error MSB4184 The expression "[MSBuild]::MakeRelative(C:\ReactCSharp, *Undefined*)" cannot be evaluated. Illegal characters in path. C:\ReactCSharp\node_modules\react-native-windows\PropertySheets\Autolink.props ReactCSharp.Package C:\ReactCSharp\node_modules\react-native-windows\PropertySheets\Autolink.props 12

    If that's a case,open the file in the path node_modules\react-native-windows\PropertySheets\Autolink.props and replace the following line:

    <AutolinkCommandArgs Condition="'$(AutolinkCommandArgs)' == '' And '$(SolutionPath)' != '' And '$(ProjectPath)' != ''">--check --sln $([MSBuild]::MakeRelative($(AutolinkCommandWorkingDir), $(SolutionPath))) --proj $([MSBuild]::MakeRelative($(AutolinkCommandWorkingDir), $(ProjectPath)))</AutolinkCommandArgs>

    with

    <AutolinkCommandArgs Condition="'$(AutolinkCommandArgs)' == '' And '$(SolutionPath)' != '' And '$(SolutionPath)' != '*Undefined*' And '$(ProjectPath)' != ''">--check --sln $([MSBuild]::MakeRelative($(AutolinkCommandWorkingDir), $(SolutionPath))) --proj $([MSBuild]::MakeRelative($(AutolinkCommandWorkingDir), $(ProjectPath)))</AutolinkCommandArgs>

  5. Open a terminal on the folder which contains the project and run the following command:

    yarn start

  6. Open the Start menu and launch the appservicedemo.Package application.
