Asp.Net Core 本地化无法使用 VSCode

Question

我正在使用 VSCode 创建一个 Asp.Net Core API。我整天都在努力弄清楚如何使本地化起作用，但没有任何结果。当我在 Visual Studio 2015 Community Edition 中执行完全相同的操作时，一切正常。但不是 VSCode...

于是我在VSCode中用最简单的结构创建了以下超级简单的项目：

我正在使用 Postman 在 http://localhost:5000/app 上发送 Http Get。结果json是这样的：

{
  "name": "test_value",
  "value": "test_value",
  "resourceNotFound": true
}

VS Community 项目类似：

结果json是这样的（右边那个）：

{
  "name": "test_value",
  "value": "This is the test value!",
  "resourceNotFound": false
}

谁能弄清楚为什么这在 VSCode 内部不起作用？在这两种情况下，我都在运行 Kestrel，这两个项目都可以正常编译，并且都具有完全相同的以下源代码。问题存在于 Windows 和 linux 开发环境中。这让我抓狂！

Controllers.AppController.resx

<?xml version="1.0" encoding="utf-8"?>
<root>
  <!-- 
    Microsoft ResX Schema 

    Version 2.0

    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.

    Example:

    ... ado.net/XML headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">2.0</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
        <value>[base64 mime encoded serialized .NET Framework object]</value>
    </data>
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
        <comment>This is a comment</comment>
    </data>

    There are any number of "resheader" rows that contain simple 
    name/value pairs.

    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.

    The mimetype is used for serialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:

    Note - application/x-microsoft.net.object.binary.base64 is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.

    mimetype: application/x-microsoft.net.object.binary.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.soap.base64
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/x-microsoft.net.object.bytearray.base64
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.

Answer 1

我终于明白了！

问题是项目文件夹的名称与根命名空间不同！项目的文件夹名称类似于 my-app。那是我为我的 Github 存储库选择的名称。所以 my-app 是我克隆存储库时创建的项目文件夹的名称，也是生成的程序集的名称（ my-app.dll) 从项目文件夹继承它的名称。但是，我选择的根命名空间是 MyApp。

我对 VS 社区没有任何问题的原因是，当我创建项目时，我为解决方案选择了名称 MyApp，所以这也是项目的文件夹名称和根命名空间！

我不确定实际问题是文件夹的名称还是生成的程序集的名称。我猜这是程序集名称。

因此，归根结底，要使本地化工作项目的文件夹名称（也就是生成的程序集的名称）必须与根命名空间相同！
