错误:

解决方法:
在webconfig 增加一下标记
<aspNetCore processPath="dotnet" arguments=".\HC.EM.DC.WebHost.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" >
        <environmentVariables>
          <environmentVariable name="Path" value="D:\Apps\hc-kc\clidriver\bin" />
        </environmentVariables>
  </aspNetCore>
