In-Place Compilation using ClientBuildManager.CompileFile

Question

I\'m working on a website that I\'d like to use in-place compilation on in order to make the first hit faster. I\'d like to use the ClientBuildManager.CompileFile method to do

I think that what you're seeing is actually unrelated to the use of CompileFile vs PrecompileApplication. i.e. if you were to do the same thing but call PrecompileApplication(), you still would get a folder mismatch.

Note that technically, you are not creating the CBM object correctly. The correct way of calling it is to rely on IIS information to locate the files. To do this:

• Pass something like /LM/W3SVC/7/ROOT/ for appVirtualDir
• Pass null for appPhysicalSourceDir

Note that the '7' is just an example. To get the correct number:

• Run inetmgr
• Go to the advanced settings for the site
• Find the site ID. That's the number you want in /LM/W3SVC/ID/ROOT/

I'm explaining this for the record, because unfortunately, I was not able to get the folders to match even in this way. It's possible that this scenario is just broken in ASP.NET (it used to work!).

An alternate possibility is to do it server side. e.g.

• include a page in your site that you'll use to trigger selective precompilation.
• In there, call BuildManager.GetCompiledType("~/myfile.aspx"), and similar calls for each page (or user control, etc) that you want to precompile.
• When you want to trigger your custom precompilation, just request that page

Of course, there is also the low tech alternative of simply requesting the pages you want compiled ahead of time to warm up your site.
