一、自动回收问题，应用程序池配置（两个都需配置）

1、闲置时间间隔设置为0

2、闲置超时设置为0

二、接口Delete/Put等请求405问题（二选一）

1、Delete/Put等类型的请求会出现405,原因是IIS开启了WebDAVModule模块,在iis的模块里删除即可

2、在配置文件里添加

<system.webServer>
        <modules>
            <remove name="WebDAVModule" />
        </modules>
    </system.webServer>

三、卷影（无占用）复制发布替换（热更新）

1、web.config文件添加如下配置

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <!-- To customize the asp.net core module uncomment and edit the following section.
  For more info see https://go.microsoft.com/fwlink/?linkid=838655 -->

  <system.webServer>
    <handlers>
      <remove name="aspNetCore"/>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModulev2" resourceType="Unspecified"/>
    </handlers>
    <aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout">
      <handlerSettings>
        <handlerSetting name="experimentalEnableShadowCopy" value="true" />
        <handlerSetting name="shadowCopyDirectory" value="../ShadowCopyDirectory/" />
        <!-- Only enable handler logging if you encounter issues-->
        <!--<handlerSetting name="debugFile" value=".\logs\aspnetcore-debug.log" />-->
        <!--<handlerSetting name="debugLevel" value="FILE,TRACE" />-->
      </handlerSettings>
    </aspNetCore>
  </system.webServer>
</configuration>
