asp.net-core - 无法加载 csproj 的项目文件

Question

我使用此链接 https://learn.microsoft.com/en-us/aspnet/core/migration/1x-to-2x/ 将我的 .netcore 1.1 项目迁移到 2.0

但是当我执行“dotnet Restore -v d”时，出现以下错误:

Build started 10/23/2017 19:57:01.
     1>Project "someproj.csproj" on node 1 (Restore target(s)).
     1>Building with tools version "15.0".
     1>someproj.csproj(1,1): error MSB4025: The project file could not be loaded. Data at the root level is invalid. Line 1, position 1.
     1>Done Building Project "someproj.csproj" (Restore target(s)) -- FAILED.

Build FAILED.

       "/someproj/someproj.csproj" (Restore target) (1) ->
         /someproj.csproj(1,1): error MSB4025: The project file could not be loaded. Data at the root level is invalid. Line 1,

position 1.

    0 Warning(s)
    1 Error(s)

这是 dotnet --info 的输出

.NET Command Line Tools (2.0.0)

这是我的 csproj 文件

结果发现文件中有一些特殊字符在 VSCode 中不可见。当我在 Vim 上打开文件时，它显示了一些不需要的字符......删除这些字符解决了问题
