WPF - error: [xxx] "does not contain a definition for [zzz] and no extension method [zzz] could be found
提问by Eric Ouellet
I get an error while compiling:
编译时出现错误：
'SimulatorUi.MainWindow' does not contain a definition for 'UserCtrlSimulator' and no extension method 'UserCtrlSimulator' accepting a first argument of type 'SimulatorUi.MainWindow' could be found (are you missing a using directive or an assembly reference?)
“SimulatorUi.MainWindow”不包含“UserCtrlSimulator”的定义，并且找不到接受“SimulatorUi.MainWindow”类型的第一个参数的扩展方法“UserCtrlSimulator”（您是否缺少 using 指令或程序集引用？）
I got this error while compiling a user control and its owning window in the same project.
在同一项目中编译用户控件及其所属窗口时出现此错误。
Why ?
为什么 ？
采纳答案by Eric Ouellet
The problem is the naming of the userControl in its owning Window. I named as:
问题是 userControl 在其拥有的 Window 中的命名。我命名为：
Name="UserCtrlSimulator"
instead of:
代替：
x:Name="UserCtrlSimulator"
You can find the bug and a more useful error message by removing the reference of that badly named object (remove any reference to the object named without the "x:").
您可以通过删除该名称错误的对象的引用（删除对不带“x:”命名的对象的任何引用）来找到错误和更有用的错误消息。
I can't tell the exact reason why it is like this ??? But my solution works fine.
我不知道为什么会这样的确切原因？？？但我的解决方案工作正常。
Hope it can help anybody because I lost a lots of time with this weird bug.
希望它可以帮助任何人，因为我在这个奇怪的错误上浪费了很多时间。
