know the difference between NGen and aspnet_compiler. Ngen create a machine native code which is cached to disk. aspnet_compiler precompiles the site. Isn't both the things same? I would be more interested to know when to use which tool?

I got to know about NGen (http://msdn.microsoft.com/en-us/magazine/cc163808.aspx) tool and
very much interested in this.
Will this create machine code? What will the output format, an EXE?
How must speed will it improve over interpreted MSIL?
Even with NGen output will we still need the CLR to run it? If so why, because in that case still CLR is interpreting isn't it?
During ASP.NET precompilation of our .NET 3.5 web application, various initialization is performed in type initializers. One of the type initializers throws a custom exception when the environment is incorrectly configured. However, when our custom exception is thrown, here is what the aspnet_compiler.exe tells us:
[exec] error ASPRUNTIME: Type is not resolved for member 'App.Project.CustomException,App.Project, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
[exec]
[exec] [SerializationException]: Type is not resolved for member 'App.Project.CustomException,App.Project, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
[exec] at System.Web.Compilation.BuildManagerHost.PrecompileApp(ClientBuildManagerCallback callback)
[exec] at System.Web.Compilation.ClientBuildManager.PrecompileApplication(ClientBuildManagerCallback callback, Boolean forceCleanBuild)
[exec] at System.Web.Compilation.ClientBuildManager.PrecompileApplication(ClientBuildManagerCallback callback)
[exec] at System.Web.Compilation.Precompiler.Main(String[] args)
Notice that no "real" stack trace information is included. However, when I change our code to throw an InvalidOperationException (instead of our custom exception), the stack trace is included correctly. (As an aside, our CustomException type is annotated with [Serializable]. When we remove the [Serializable] annotation, the aspnet_compiler.exe complains differently -- that our custom exception is not marked as such.) Does anyone know why throwing a custom exception during ASP.NET precompilation is causing the secondary SerializationException? Why is it trying to serialize the exception? Similarly, why does using a BCL InvalidOperationException not cause the secondary SerializationException?
Could this be because the aspnet_compiler.exe is trying to do some sort of reflection on unexpected exceptions? (And therefore since it does not have our App.Project assembly loaded, it is unable to resolve the type?)
The several different environments (e.g. live, demo etc) of my web app are differentiated by config settings in a folder called EnvironmentConfiguration. Whenever I update one of the sites, I delete the EnvironmentConfiguration folder from the precompiled site before copying the website files over (i.e. in order that the EnvironmentConfiguration folder in the deployment location is not replaced). Just to save mistakes, is there a way I can get Visual Studio not to produce the EnvironmentConfiguration folder when it precompiles the site for me?

View 1 RepliesI thought that <%: had replaced <%=, since mentions on [URL]Prior to ASP.NET 4, the <%= %> syntax was used to execute code and write it out to the page. Starting with ASP.NET 4, you should always use the <%: %> syntax instead..."
However, I've noticed that
<img src='<%=ResolveUrl("~/Images/MyImage.jpg")%>' alt="blah">
works, whereas
<img src='<%: ResolveUrl("~/images/MyImage.jpg")%>' alt="blah">
doesn't.
I'm not sure what the name for these types of expressions are so I've had trouble googling it.

ASP.NET “special” tags
I hope this isn't too much of a newbie question. I seem to always use the correct syntax, but I don't really understand why I'm using the <%: and <%= in ASP.NET, and I was hoping someone could clarify for me. I found this article which explains <%= and <%#, but wasn't able to find anything in Google on <%:.
Examples of where I have used the various syntax:
<div>
<%: Html.LabelFor(model => model.Type) %>
<%: Html.TextBoxFor(model => model.Type)%>
</div>
and
<div id="header-menu">
<ul>
<li><%= Html.ActionLink("Home", "", "Home" )%></li>
</ul>
</div>

View 4 RepliesI am in the process of learning MVC, and thought I would parallel the work in both C# and VB.NET. I ran into a snag when right-clicking in an action method inside of a controller to add a view - in C# if I choose to strongly type the view it includes all the objects in the models folder in the drop-down list for selection; however, in VB.NET none of the models are available in the list. Is there some step I need to take in order to make the models objects available in the drop down for selection?

View 3 RepliesI'm starting to learn ASP.NET and going through the tutorial videos on www.asp.net. I understand the basic concept of web application frame works like ASP/PHP/ASP.NET. HTML/XHTML is created with special tags that the server knows to read and replace with content. I did a little bit with ASP during a summer internship back in the 90's.
Yet with the few examples of ASP.NET I've seen so far it seems ASP.NET has two types of server interpreted tags.
Most of the time I see <asp:XXXX > tags such as
<asp:ContentPlaceHolder ID="HeadContent" runat="server">
</asp:ContentPlaceHolder>
but I also see regular ASP tags like
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="TailspinSpyWorks.SiteMaster" %>
What is the difference between these two tag formats? Both are interpreted by the server correct? Why would I use one over the other?

What is the difference between <% %> and <%= %>
I assume this means the same using either Webforms or MVC.
I want to build my own web framework, and I want to build it in C#. I figure the easiest way to get started is to use ASP.NET to handle all the server communication stuff. The rest I want to build my self. I know next to nothing about ASP.NET. (But know C#, the MVC pattern, and other web frameworks quite well).
In Visual Studio 2010 I see
ASP.NET Web Application
ASP.NET MVC 2 Empty Web Application
ASP.NET MVC 3 Empty Web Application
I figure one of these should be good as a base. I just want some "entry point" into some C# code. I started with PHP so it's a little bit weird for me to not be able to just load up a file in my browser. Anyway, which should I use? What's the difference between a plain ASP.NET Web App and an empty MVC 3 app? If it's "empty" it shouldn't be using any of the MVC framework, should it? I just want to make sure I use the latest and greatest "ASP" for handling the server stuff before I embark down this road.
