@Wayne, @Farhan, @Shaun, @Julian, @Thomas, @Eamonn,

Glad that it worked for you and saved you some hours.

@Brian,

Glad that it worked for you as well and thank you for posting that it worked using Application_Start.

@Reid,

Unfortunately, I am not aware of any unofficial/official reason for the decision.

@Guanluca,

I have the work-around running on several IIS 6 hosted websites on different servers. We only have a wildcard mapping and the initialization code is located within the AppInitialize class.

Thank you for your post it really helped. Did anyone at MS every come back to you with reasons for the decision?

Hi,
I’d tryed this workaround on IIS 6 but it never works if I put this code in global.asax nor in appinitialize.

My project has a root folder with a regular web application, and the a “virtual” folder, a folder that not exists physically, but I’ve develop VirtualPathProvider to see that if I call this folder has to render pages in a assembly, where is another website with aspx,ascx,js, css and more.

On my IIS 6 I’d set up wildcards for asp.net.

I’d solved the problem using HttpModules and in the init function I call your solution and works fine to run the first page…

But there’s another problem…If in my website have a reference to a assebly created I receive everytime an error like this

Retrieving the COM class factory for component with CLSID {10020200-E260-11CF-AE68-00AA004A34D5} failed due to the following error: 80040154.

seems that I can’t use assebly different from the system…

Have you some ideas about this?

Has anybody been able to get this to work with a non-updateable web deploy?
(by using the property pages and de-selecting ‘allow this precompiled site to be updateable’)

Meaning, just using the placeholder .aspx files and no .ascx files?

I’m getting an error that it can’t find my user controls (.ascx) because they compiled into a .dll and they don’t exist on the file system.

For once a blog posting that actually helped me solve a problem. That you so much. I replaced the call to HostingEnvironment.RegisterVirtualPathProvider directly in Application_Start with the reflection calls to the internal version of the method and it worked.

Thanks for the solution. Like others commenting, I only discovered the pre-compilation issue after I had written the code and was very relieved to find your article.

Hi All,

I have to host it on my Local PC with Execute Permissions is set to Scripts and Executable only and it does not work, it seems the VPP is not registered. Whereas when it’s set to Scripts only, it works fine. Can you please help me to figure it out?

Hello Asang,

Have you tried that already?
