## Install vs 2019 Professional/Enterprise version

Firstly, you need to Install vs 2019 Professional/Enterprise version. Then installing .net core 3.0 SDK is needed. Now you can try to create a .net core WPF application,

After setting the relevant project name and storage path, it will pop up:

## Check "Use preview SDK" under .NET core in VS options

After setting done, restart vs to take effect.

## Use VS build-in template, create WPF Project named "CoreHiWPF" of .net core

## Under the created solution, use VS build-in template to create new WPF project "HiWPF" of .net framework type

Now the file structure of the solution is below:

## Update Assembly Name of .net core WPF "CoreHiWPF", make Assembly Names of two projects are the same

Right click the project `CoreHiWPF`, select `Properties`, then change its `Assembly Name` to `HiWPF`.

Then right click the project, click "Edit CoreHiWPF.csproj".

Add code as below:

[![1555773381960](https://github.com/yanglr/.netCore-WPF_Designer/raw/master/screenShots/1555773381960.png)](https://github.com/yanglr/.netCore-WPF_Designer/blob/master/screenShots/1555773381960.png)

```
  <ItemGroup>
    <ApplicationDefinition Include="..\HiWPF\App.xaml" Link="App.xaml">
      <Generator>MSBuild:Compile</Generator>
    </ApplicationDefinition>
    <Compile Include="..\HiWPF\App.xaml.cs" Link="App.xaml.cs" />
  </ItemGroup>

<ItemGroup>
    <Page Include="..\HiWPF\MainWindow.xaml" Link="MainWindow.xaml">
      <Generator>MSBuild:Compile</Generator>
    </Page>
    <Compile Include="..\HiWPF\MainWindow.xaml.cs" Link="MainWindow.xaml.cs" />
  </ItemGroup>
```

## Ensure .net core WPF project CoreHiWPF is set as start up project

If the .net core WPF project `CoreHiWPF` is already highlighted, you can ignore then. Or, you need to select project `CoreHiWPF`, then right click `Set As Start up project`.

## Try XAML Designer

Now close all opened files. Click the file `MainWindow.xaml` of project `HiWPF`. Then you can see empty WPF window in XAML designer now.

## Modify the file MainWindow.xaml and related .cs if needed
Then, I add two lines to `Grid` of the file `MainWindow.xaml`:
- One line is a `Label` which support Wrap
- The other line is a `Exit` button.

Then I added the `Click` event to `Exit` button, added the `Loaded` event to `Window`.
