加载项目时出错：无法识别属性包含

Question

After merging two branches the Visual Studio has suddenly problems with loading a project. When I try to reload, I always get the error

The attribute "Include" in element Reference is unrecognized.

I have no idea why this happened... how can I get the solution to load the project again? Has anyone encountered this error message before and know what I have to look for to find the problem?

The .csproj doesn't really look corrupt on the first sight...

Thanks in advance

Answer 1

我发现了错误...与没有关闭标签的参考标签存在合并冲突，因为它在合并时被删除。

Answer 2

when you build the csproj file with MSBuild you get the line-number on which the error occurs. This is unfortunately not visible in VisualStudio.

• Open the Develop Commnand Prompt for Visual Studio
• Navigate to the folder which contains the csproj file
• Run MSBuild

In the error, it contains the line-number with the error in the csproj file. This helped me fixing the file after a GIT merge

对我来说，xeraphim 的答案实际上为我指明了正确的方向，但对我来说，我的 csProj 文件中有一个额外的</Reference>标签，希望这对某人有所帮助。

Answer 4

在 macOS 上，我无法解决它，直到我删除 VS 2019 然后再次安装它，这很好地修复了它:)

Answer 5

我的情况是我有嵌套的 Reference 标签，这个错误是由使用 Git 扩展的 kdiff3 插件触发的。
