添加内容页面VS时Xamarin System.Exception [英] Xamarin System.Exception when adding Content page VS

问题描述

在Visual Studio中尝试将Content Page添加到解决方案时，发生以下错误:

When trying to add a Content Page to the solution in visual studio, the following error occurs:

Exception of type 'System.Exception' was thrown.

The project system has encountered an error.

Did not find new element in the hierarchy for item `Views\MyPage.xaml`.
The item would have been added with type "Page".
The project item schema service knows about this item type.
The item does exist in the project file.

添加文件时，请执行以下操作:

When adding the file I do the following:

Right click on Views in my Xamarin Solution > Add > New Item > Content Page > Add

在Windows资源管理器中查看时，会创建一个文件MyPage.xaml，但尚未创建MyPage.xaml.cs，并且未将其添加到解决方案中

When looking in the windows explorer, there is a file created MyPage.xaml but it has not created MyPage.xaml.cs and it is not added to the solution

这是一个空白的Xamarin共享项目，并且此错误不断发生...

It is a blank Xamarin shared project and this error just keeps happening...

这让我发疯，因为我什至无法添加单个页面

It's driving me nuts as I can't even add a single page

作为一种解决方法，我使用W.explorer手动添加文件，然后手动编辑app.projitems，但这很荒谬.

As a workaround, I add the files manually using the W. explorer and then edit app.projitems manually, but this is just ridiculous.

推荐答案

在解决此问题之前，作为一种肮脏的解决方法，将文件手动"添加到项目中即可完成工作.

As a dirty workaround until this gets fixed, adding the files "manually" to the project gets the job done.

在Visual Studio关闭的情况下，

With Visual Studio closed,

1. 复制/粘贴现有​​的(正在运行的)*.xaml和* .xaml.cs文件(重命名) 他们随便你)
2. 使用文本打开新粘贴的文件 编辑器(不是VS)，然后将内容重命名为您在#1中选择的名称
3. 将新粘贴的文件添加到* .projitems文件(以文本形式打开) 编辑器中，搜索您在#1中复制的文件名并添加新文件名 类似地)-将有3个地方添加它们

1. copy/paste existing (working) *.xaml and *.xaml.cs files (rename them as you please)
2. open the newly pasted files with a text editor (not VS) and rename the contents to your chosen name in #1
3. add newly pasted files to your *.projitems file (open it in a text editor, search for the filenames you copied in #1 and add the new ones similarly) - there'll be 3 places to add them

现在在VS中打开解决方案并重新构建-它应该看起来并构建良好.

Now open the solution in VS and rebuild - it should look and build fine.
