1.安装MiniProfiler包
PM> Install-Package MiniProfiler
2.在Views下的web.config中引入命名空间：
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="StackExchange.Profiling" />
......
</namespaces>
</pages>
3.在_Layout</body>前加入：
@MiniProfiler.RenderIncludes();
4.在Global.asax中加入：
protected void Application_BeginRequest()
{
if (Request.IsLocal) { MiniProfiler.Start(); } //or any number of other checks, up to you
}
protected void Application_EndRequest()
{
MiniProfiler.Stop(); //stop as early as you can, even earlier with MvcMiniProfiler.MiniProfiler.Stop(discardResults: true);
}
5.在web.config中加入(如果MiniProfiler不展示任何信息)：
<system.webServer>
...
<handlers>
<add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />
</handlers>
</system.webServer>
