Question

• 我使用的SkyAPM.Agent.AspNetCore版本是最新版本的2.1.0，在本地监控运行的.NET CORE项目是正常的，但是我将.net项目配置成IIS程序后，我的skywalking 9.3 就接收不到数据，并且 SkyAPM.Agent.AspNetCore 的日志也并没有生成，我也尝试在issue中寻找答案，看到有大佬说需要在web.config中配置环境变量，下方是我的web.config配置文件，不幸的是，配置之后，接口都不能正常访问，抛出500的错误，请大佬帮忙解答一下

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\WebApplication1.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
		<environmentVariables>
			<environmentVariable name="ASPNETCORE_HOSTINGSTARTUPASSEMBLIES" value="SkyAPM.Agent.AspNetCore" />
		</environmentVariables>
       </aspNetCore>
    </system.webServer>
  </location>
</configuration>

目前我是通过在IIS 配置编辑器当中配置环境变量可以解决了问题了
