如何将 Wpf 项目迁移到新的 VS2017 格式

How-to migrate Wpf projects to the new VS2017 format

提问by Niek Jannink

I'm migrating my projects to the new visual studio 2017 format which is working nicely for all standard libraries only now I run into problems with my UI libraries where I use Wpf / Xaml.

我正在将我的项目迁移到新的 Visual Studio 2017 格式，该格式仅适用于所有标准库，现在我在使用 Wpf/Xaml 的 UI 库中遇到了问题。

I cannot figure out howto do this for my user controls. The old item doesn't seem to be valid anymore.

我无法弄清楚如何为我的用户控件执行此操作。旧项目似乎不再有效。

Anybody has an idea howto do this or if it's even possible.

任何人都知道如何做到这一点，或者甚至可能。

上一个答案

You can use template below to replace old .csproj with. It resolves couple of issues other people templates had.

您可以使用下面的模板来替换旧的 .csproj。它解决了其他人模板的几个问题。

1. You don't have to include intermediary *.g.csfiles like some suggested to do.
2. No Main not founderror will occur.
3. No Unable to run your project. The "RunCommand" property is not defined.error will occur.
4. Includes already configured default Settings and Resources.

1. 您不必*.g.cs像建议的那样包含中间文件。
2. 否Main not found会发生错误。
3. 否Unable to run your project. The "RunCommand" property is not defined.会发生错误。
4. 包括已配置的默认设置和资源。

The above solution works for Wpf dll's, but I reverted it because Resharper and the Visual Studio designer where not functional anymore after this change. Mainly because they couldn't pair the xaml and the code-behind at design time. But the project compiles and works.

上述解决方案适用于 Wpf dll，但我将其还原，因为 Resharper 和 Visual Studio 设计器在此更改后不再起作用。主要是因为他们无法在设计时将 xaml 和代码隐藏配对。但是该项目可以编译并运行。

For a wpf executable you need to do the following:

对于 wpf 可执行文件，您需要执行以下操作：

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>

    <TargetFramework>net451</TargetFramework>

There's Sunburst.NET.Sdk.WPFthat allows to use it as .NET SDK. Here's complete example for WPF application where any .csand .xamlfiles will be included automatically:

有Sunburst.NET.Sdk.WPF，允许使用它作为.NET SDK。在此处，任何对WPF应用程序完整的例子.cs和.xaml文件将包含自动：

<Project Sdk="Sunburst.NET.Sdk.WPF/1.0.47">
  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net40</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <ProjectReference Include="../WpfMath/WpfMath.csproj" />
  </ItemGroup>
</Project>

When you build this project with msbuild(notably I had no luck with dotnet buildthough), it will automatically download SDK from NuGet and set everything up.

当你用它构建这个项目时msbuild（特别是我没有运气dotnet build），它会自动从 NuGet 下载 SDK 并设置一切。

Now that .NET Core 3 has been released, you should use it if you can.

现在 .NET Core 3 已经发布，如果可以，您应该使用它。

But if not, I've found that I can create a separate Shared project for only the XAML items, and I can reference that project from the SDK-style project. Everything builds properly.

但如果没有，我发现我可以只为 XAML 项目创建一个单独的共享项目，并且我可以从 SDK 样式的项目中引用该项目。一切正常。

Note that the XAML designer doesn't work -- no Intellisense or red squigglies. Visual Studio opens the XAML files with the XML editor.

请注意，XAML 设计器不起作用——没有 Intellisense 或红色波浪线。Visual Studio 使用 XML 编辑器打开 XAML 文件。
