步骤

安装Release Management Utility tasks

将 Tokenizer 添加进BuildStep

编写webConfigReplace.json，并提交到tfs

{
  "default": {
    "CustomVariables": {
    "Variable1": "value1",
    "Variable2": "value2"
  },
    "ConfigChanges": [
        {
          "KeyName": "/configuration/metaModel",
          "Attribute":"configSource",
          "Value":"Config\\MetaModel.config"
        },
        {
          "KeyName": "/configuration/connectionStrings",
          "Attribute": "configSource",
          "Value": "Config\\ConnectionStrings.config"
        }
      ,
      {
        "KeyName": "/configuration/runtime/assemblyBinding/probing",
        "Attribute": "privatePath",
        "Value": "bin;binMP;binQF"
      }
      ,
        {
          "KeyName": "/configuration/system.web/compilation",
          "Attribute":"debug",
          "Value":"false"
        }
    ]
 }
}

注意：此处default为Environment name，若未配置Environment name，则指定default即可

配置Configuration Json filename： $(Build.Repository.LocalPath)/src/XXX/webConfigReplace.json

注意，此处必须使用$(Build.Repository.LocalPath)变量获取文件根路径。

另外，

1)若要使用_XXX_格式替换web.config 中的标记为变量，变量不支持系统内部变量，若要使用系统内置变量，如$(Build.SourceVersion)

可以新建一个用户变量，然后设置其值为$(Build.SourceVersion)

2)若config节点有namespace，则需要指定

{
"NamespaceUrl": "urn:schemas-microsoft-com:asm.v1",
"NamespacePrefix": "asm",
"KeyName": "/configuration/runtime/asm:assemblyBinding/asm:probing",
"Attribute": "privatePath",
"Value": "bin;binMP;binQF"
}
