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，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)
