從1.1.1升級錯誤：'FileMode'存在於'System.IO.FileSystem.Primitives'和'System.Runtime，Version = 4.2.0.0

Question

將我的項目更新到1.1.1後，以下兩行不會工作： var d = new FileStream(Path.Combine(PathToFile, $"{fileName}.txt"), FileMode.Open); var fs = new StreamReader(d,Encoding.UTF8);

當我將chane恢復到csproj文件時，錯誤消失。我究竟做錯了什麼？

我得到以下錯誤：

1. 錯誤CS0433類型 '的StreamReader' 存在於兩個 'System.IO，版本= 4.1.0.0，文化=中性公鑰= b03f5f7f11d50a3a' 和「System.Runtime .Extensions，Version = 4.2.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'
2. 錯誤CS0433'System.IO.FileSystem.Primitives，Version = 4.0.1.0，Culture = neutral，PublicKeyToken'中存在'FileMode' = b03f5f7f11d50a3a'和'System.Runtime，Version = 4.2.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'
3. 錯誤CS0433類型'編碼'System.Text.Encoding，Version = 4.0.10.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'和'System.Runtime，Version = 4.2.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'
4. 錯誤CS0433 「System.Text.Encoding，Version = 4.0.10.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a」和「System.Runtime，Version = 4.2.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'
中都存在類型'Encoding'
5. 錯誤CS1503參數1：無法從 '串' 到 'System.IntPtr'

Rebuilding the nuget package fixes it. Go to %USERPROFILE%/.nuget and clear it all.

@ericwj According to joe on web tools team, that’s a known issue. There was one build of the BrowserLink package that had bad references, and that’s apparently the one that shipped with the .NET Core 1.1 CLI installer. However, in RC.3, we removed BrowserLink from the Core 1.1 template, so it shouldn’t be an issue with new projects.
