c# - '输入字符串的格式不正确。' 在使用程序集版本“1.0.0.*”时从 C# 中的 .NET 核心应用程序打开新窗口时

Question

我最近在 C# 中使用 Visual Studio 2019 创建了一个 .NET 核心 WPF 应用程序，并将程序集版本更改为最后自动生成（“1.0.0.*”）。

我使用 WPF 应用程序多次执行此操作都没有问题，但使用 .NET 核心时，每当我尝试从主窗口创建新窗口时，都会收到以下错误消息：

System.FormatException: 'Input string was not in a correct format.'

我用来创建新窗口的代码如下（按下按钮）：

About windowHelp = new About();
windowHelp.Owner = this;
windowHelp.WindowStartupLocation = WindowStartupLocation.CenterOwner;
windowHelp.Show();

我确实将以下内容添加到 .CSPROJ 文件中（使用文本编辑器）：

    <Deterministic>false</Deterministic>

每当我将程序集版本恢复为“1.0.0.0”时，一切正常。

有人可以帮我解决这个问题吗？目标是删除“输入字符串的格式不正确”。消息，同时保持“1.0.0.*”程序集版本。

感谢您的时间和帮助，非常感谢。

注意：这是添加“*”的地方。

我会得到一个堆栈跟踪。

从GitHub dotnet/wpf #2517 复制：对于非确定性构建 WPF 应用程序在资源字典加载时崩溃InitializeComponent()，会生成以下内容：

public void InitializeComponent()
{
    if (!_contentLoaded)
    {
        _contentLoaded = true;
        base.set_StartupUri(new Uri("MainWindow.xaml", UriKind.Relative));
        Uri resourceLocater = new Uri("/NetCoreWpfNonDeterministic;V1.0.0.*;component/app.xaml", UriKind.Relative);
        Application.LoadComponent((object)this, resourceLocater);
    }
}

那是一个错误。有人会怀疑这个错误就在附近MarkupCompiler.cs#L2606，或者更确切地说是在它上面的某个地方。

这看起来像是一个先有鸡还是先有蛋的问题，因为标记编译器（将 XAML 转换为 IL）还不知道程序集的版本号，但我不确定。

无论如何，除了将资源放在具有固定版本号的程序集中之外，这不是您可以轻松解决的问题。
