I'm working through the Mvc Music store tutorial on PDF. At page 52, near the bottom, is a line that reads:
<%: Html.EditorFor(model => Model.Album, new {Artists = Model.Artists, Genres = Model.Genres})%>
This line fails with an "unhandled compile" error when I run the program and enter "storemanager/edit/388" in the address bar. I have gone over every bit of code I can find and it compares perfectly to the tutorial.
Several production websites running for months with no problems, all of sudden now fail to compile sporadically.
The compiler will generate errors:
ASPNET: Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl).
On master page code behind files that it did not before.
In addition, this error will go away (most of the time) if we recycle the application pool.
I'm using IIS 7.5 on Server 2008 R2 to configure a .Net 4-based website. I've used the Web Deployment Tool to import a known-good, 32-bit Windows 7-based IIS server package. As far as I can tell, the 2008-based IIS server and application pool are now properly configured to use .Net 4, and that the server setup is identical to that of the known-good configuration.The problem I'm having is that when I attempt to load a page on the new site, IIS returns a compilation error of the .Net framework's web.config. The error is copied below. It's my understanding that a properly-configured server shouldn't have any problem compiling this file, so I'm looking for some pointers on what I can do to resolve this. I've verified that:
both .Net 4 and .Net 3.5.1 are installed on the server, the 'default' page at http://localhost loads properly http://localhost/Services, the root folder of my application, can be browsed commenting out the offending System.Xml.Linq namespace simply results in a compilation error of some other namespace in the same group.
Server Error in '/Services' Application.

I am trying to figure out how to publish a web app from a command line if there isn't a solution file present. Is this possible? Is it possible to generate a solution file from the command line? I would need example of how this is accomplished.
View 2 RepliesEvery once in a while, when I'm editing an aspx or ascx page, Visual Studio will start telling me there is an error on the first line of my file. For instance, right now, it is saying Argument missing on line 1. That line is just your typical header, with no apparent problems (to my eyes), and I hadn't even changed that one when the error started appearing.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MyControl.ascx.cs"
Inherits="MyNamespace.MyControl" Debug="true" %>
Unlike most compile errors, the build still succeeds. (At least this time it did.)
It's worth noting that no other errors or warnings are thrown by this file or its as[p|c]x.cs
Sometimes, to get out of it, I am forced to undo my changes until it disappears and carefully redo what I wanted. This time, grasping at straws, I cleaned and rebuilt the solution. While I was typing this, the error disappeared, sometime after the rebuild finished.
I have a suspicion that it often happens when I tinker with the databinding in my markup. Sometimes it seems to appear if I'm missing a space inside a tag before its closing slash, like so:
[...] Text='<%# Eval("Field") %>'/>
versus:
[...] Text='<%# Eval("Field") %>' />
...But that doesn't seem to have been the problem in this case.
When coding PHP and Perl, sometimes the interpreter would throw an error referencing the very last line of the file. Over time, I learned to look for imbalanced brackets and other delimiters somewhere up above. This problem in ASP.NET feels similar, but stranger, since it's the first line, and not just something amiss above, cascading down to the bottom. Or is it just Visual Studio getting temporarily confused? Can any pros shed some light on this problem, with reasons why it happens? I'd like to have some logic (as opposed to my own built up superstition) to throw at this the next time it rears its ugly head.
I have a Perl script that calls aspnet_compiler.exe to compile a large ASP.NET website. The problem is that it takes very long to run. Is there any way to compile just a single .aspx file from the command line? (I think that would suit the needs of my script) It seems that all aspnet_compiler.exe can do is compile at a directory level.

View 1 RepliesI have several class files in App_Code in an ASP.net website running in Microsoft Visual Studio 2005 Professional.In liu of using a full unit test suite I just want to somehow compile those project-wide classses into an .EXE so that I can nightly run unit tests on them.I do know how to create a separate C# library project consisting of those files and how to include them into my website--but that is not desirable--I don't want to give up the ability to make on-the-fly code changes of those library classes when running the website in the debugger. As far as I know .Net debugger isn't powerful enough to modify code in included libraries with instant auto re-compilation on page re-load.So, I want my cake and eat it, too:
Command-line unit testing of website class files in App_Code directoryBeing able to modify those class files w/o stopping/re-starting the web debugger.

I didn't want to post anything before i search and upgrade to the latest ajax3.5I copied the zip extracted it in a location and then on vs2008 i added a toolbox and i imported the jaxcontroltoolkit.dll(the very first on the folder).
I got the controls and all is fine until then.
The problem (i previous had with the beta version) stayed.
I did not handle an exception and vs prompted me for the location of accordioncontrol.cs (i don't clearly remember the control), saying there is no source code and i should provide one.I clicked cancel (there is clearly no accordion .cs control on the zip) and the program got the exception on the web page.Ok.
Now everytime i put a breakpoint on the page and it reaches the last end sub it prompts me this "There is no source code available for the current location."I can hit F5 and pass this, however if i hit F11(next statement) it prompts me for the location of the picture i include here. I remember finding the cs somewhere for the beta and included it and it prompted me for wrong version or something on the unhandled exceptions so i have forgotten the error (because i usually handle all my exceptions so i didn't have any for a while).

It doesn't work, as I will explain further below, but it gives the compile error CS1061: 'ProductService' does not contain a definition for 'GetByid'.

I am converting some code from asp classic to c#
Need to createObject
Object obj=new Object();

It doesnt compile, I added the dll into my bin folder and into WINDOWSsystem32
I added using System.Net; what other references I need to add for it to compile?
Using VS2008 SP1, .NET 3.5 SP1, C# Web Application Project
As we know, Web Application Projects (unlike Web Site Projects) compile the entire site for deployment. We have discovered a situation where the visual studio compiler doesnt catch and error. Then when we deploy the dll to the website (or even just run it in the built in web server) it catches the error and displays it as a "compilation" error during runtime. This is obviously disturbing. Let me explain the error:
Take a single web page in a new C# web app project, such as the default.aspx. Add a checkbox. Create an event handler for the checked changed event. Note that it modifies the .aspx file to add oncheckedchanged="yourmethodhere" in the checkbox item. Compile and everything is fine.
Now change the name of the method in the .aspx file, say for yourmethodhere to yourmethodhere_1 and compile again. Note you havent change the code behind, so you SHOULD get a compile error. But you dont. Now if you deploy or debug it, you will get a compilation error during runtime.
Note: If you do exactly the same thing in a web SITE project, the validation compile that it does when you choose to "build" the project DOES catch this error. In other words, only c# web APPLICATION projects have this problem.
Everytime I compile my asp .net project it states the following:
'Sessions' does not contain a definition for 'Select'.
In the page this happens on if I change something put it back and save and re-compile it tends to go ok, but at the moment it is happening every time. It does contain a definition for Select I can type it in plus the page does not show an error where this code is and works when it does compile ok?
