傻F#\ WPF错误 - "名称'abc'在命名空间'xyz'中不存在",即使Intellisense看到它

Question

尝试从C#迁移到F#(我第一次使用MVC而不是MVVM,所以我的术语可能已关闭),但最终我无法设置我的WPF\XAML DataContext,因此我可以绑定我的UI.

我有以下简单的WPF:

<UserControl x:Class="epic.Sandbox.Controls.FieldController"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:epic.Sandbox.Controls"
             xmlns:Views="clr-namespace:epic.View;assembly=epic.Core"
             mc:Ignorable="d" 
             d:DesignHeight="300" d:DesignWidth="300">
    <UserControl.DataContext>
        <Views:TextFieldModel />
    </UserControl.DataContext>
    <Grid>

    </Grid>
</UserControl>

和以下F#:

namespace epic.View

open System
open FSharp.Desktop.UI

[<AbstractClass>]
type public FieldModelBase() = 
    inherit Model() 

    let mutable fieldCaption: string = null
    let mutable fieldValue: System.Object = null
    [<DerivedProperty>]
    member this.Caption with public get() = sprintf "%s" fieldCaption and set value = fieldCaption <- sprintf "%s" value; this.NotifyPropertyChanged "Caption"
    [<DerivedProperty>]
    member this.Value with public get() = fieldValue and set value = fieldValue <- value; this.NotifyPropertyChanged "Value"

type public TextFieldModel() =
    inherit FieldModelBase()

XAML编辑器的Intellisense可以查看我的课程,您可以从以下屏幕截图中看到:

但是当我尝试编译时,我收到以下错误:

知道我做错了什么吗？

感谢@Terrance 的评论，我手动从 WPF 解决方案中删除了“\bin”文件夹，重新启动了 Visual Studio 并重建了我的解决方案。问题解决了。愚蠢的我。
