Missing assemblies with mono 3 MVC web app - mono

I've installed the freshly released Mono 3 and MonoDevelop on my Mac, and I was keen to get a simple MVC web application working with razor view pages.
When I File-New-Solution up a MVC 3 Web Application (razor), the thing doesn't compile, giving the error:
The type or namespace GlobalFilterCollection could not be found
It's because 2 references are not working - System.Web.Helpers and System.Web.WebPages. When I look at these in the references list in MonoDevelop, they are red with "Assembly not available" - looking at the references in more detail it seems I'm referencing system.web.mvc 2.0.0.0, whereas everything else is 4.0.0.0. Can anyone advise?

I eventually got mine to run by referencing the System.Web.Mvc.dll found in /Library/Frameworks/Mono.framework/Libraries/mono/4.5/
I also had to bring over System.Web.Helpers.dll from a Windows box and update the Web.Config using one generated by Visual Studio.
There's probably a better way to do this (please be a better way), but figured I'd pass on what I found.

Add packeges "Microsoft ASP.NET MVC" and "Microsoft ASP.NET Web Pages" from NuGet.

ASP.NET MVC Website first start

Hello i am currently learning ASP.NET MV4 with Visual Studio 2012, i created a new project, not an empty project, an internet application but anytime i try to run it i keep getting an error.
There is no much else i can say about this, i am just now learning ASP.NET with Razor.
I would very much appreciate some help on this. The error itself seems to be originating from my machine.config file but i'm kinda afraid of opening that file.
This is the error:
http://prntscr.com/3a6ltl
Add MySQL.Web as your reference with NuGet Install-Package MySql.Web.
Or remove the red line from your machine.config if you are not going to use the MySQL Membership provider
It is located here: c:\windows\microsoft.net\framework\v4.0.30319\config\machine.config

Issues while upgrading System.Web.Extensions dll reference from 3.5 to 4.0

I need to migrate a website built on .net framework 3.5 to 4.0 and it should work fine in IE9
The solution got upgraded by the VS's version utility and the app compiled successfully. We are using Infragistics UltraWebGrid control v11.1 which is giving some script issue when we try to perform scroll or cell edit. The control has got lot of embedded javascript resource files which seems to be not working fine.
I created a poc website of .net framework 4.0 using the same third party dlls and everything works fine. What I can doubt on is the AJAX part. I tried to consume v4.0 of ajaxcontroltoolkit. But the issue what I am facing is, the toolkit internally references System.Web.Extensions.dll of version 4.0 and my application has many references to the dll of v3.5. Adding the reference to v4.0 doesn't replaces the references to v3.5 in the web.config. Finally I manually updated the version info in web.config which has given birth to other errors.
-Unknown server tag 'asp:ScriptManager','asp:UpdatePanel' etc..
-The type or namespace name 'Script' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)
Please give me some suggestions to upgrade the dll references successfully.
Thanks,

Where are the symbols for ASP.NET MVC 4.0 RTM?

I'm trying to configure Visual Studio 2012 to allow me to step into ASP.NET MVC 4.0 source code. (System.Web.Mvc.dll). I've followed SymbolSource's recommended configuration but when I try to load the symbols, Visual Studio can't locate them.
Recommended configuration
To configure Visual Studio for symbol/server
use, follow these instructions:
Go to Tools -> Options -> Debugger -> General.
Uncheck “Enable Just My Code (Managed only)”.
Uncheck “Enable .NET Framework source stepping”.
Yes, it is misleading, but if you don't, then Visual Studio will
ignore your custom server order (see further on).
Check “Enable source
server support”.
Uncheck “Require source files to exactly match the
original version”
Go to Tools -> Options -> Debugger -> Symbols.
Select a folder for the local symbol/source cache.
Add symbol servers
under “Symbol file (.pdb) locations”. Pay attention to the correct
order, because some servers may contain symbols for the same binaries:
with or without sources. We recommend the following setup:
http://referencesource.microsoft.com/symbols
http://srv.symbolsource.org/pdb/Public or the authenticated variant
(see above)
http://srv.symbolsource.org/pdb/MyGet or the authenticated
variant (see above) (other symbol servers with sources)
http://msdl.microsoft.com/download/symbols (other symbol servers
without sources)
I am aware that the source code is available on CodePlex, however I'm specifically interested in stepping into the code using a symbol server instead of having to unreference Mvc from the GAC and reference a locally built assembly.
Has anyone had success doing this with MVC 4.0?
Just add a symbol server that serves more then just major releases.
Try this one, contains most minor builds.
http://srv.symbolsource.org/pdb/Public
Verify:
Run VS as administrator.
Check that something have been downloaded to your symbol cache directory.
Goto select only specified modules.
Add "System.Web.Mvc.dll"
Set a break point in your code. Start debug.
When break point hits rightclick in callstack on any mvc.dll row. Verify that symbols are loaded.
if loaded, try dubbleclick on one callstack row to open mvc source.
Get back with where you get in trouble.
I will make some refinements to Luke Gumbley's anwser.
Microsoft tries to make a developer's life easier. Whenever it release an MVC version installer, there should also be a Source to download. So people can use the source to explore what is installed by the Installer, as well as to debug the MVC.
Back to the way of downloading the MVC debug info. Your Visual Studio (I use 2010) will never try to download MVC PDB files from the aforementioned servers if you have MVC4 installed on your system. In this case, your Visual Studio will use the MVC from your GAC when you run debugger.
I have tried the way suggested by Luke Gumbley. However, once you uninstall MVC, your MVC project will not be loaded, and you cannot create a new MVC project since the Template is gone. So please don't unistall MVC. If you do so, you still need to reinstall it. This wastes time.
What you really need to do is exit your Visual Studio, run command
gacutil /u System.Web.Mvc
Then go to C:\Windows\Microsoft.NET\assembly\GAC_MSIL, remove or rename the offending System.Web.Mvc folder. After this, lanuch your Visual Studio, and fetch the MVC package from NuGet.
I can't answer on your question directly and provide you URL with symbols (.pdb) for System.Web.Mvc.dll for ASP.NET MVC 4.0, but probably I can help you to solve the problem in another way.
As well known (see here for example) Microsoft provide the current source code of .NET on http://aspnetwebstack.codeplex.com/. In the post it's described how to use the Nightly version of ASP.NET (the current developer state of the code). If you didn't used Git before you can have problems with downloading RTM version of ASP.NET 4.5 (with ASP.NET MVC 4.0) which you could prefer to use instead of Nightly version. Nevertheless the downloading of the full source code of RTM version is easy enough. You need just to know that Git allows to save copy of the code in branches or tagged versions. In the way you can get access (and download it) to some previous versions of the full code. The link for example provide you jQuery 1.8.2 instead of another link get you the latest developer version which can be unstable. So to download the source code of RTM version you just need to choose "v2-rtm" branch and then click on "Download":
You can use the link to select "v2-rtm" branch directly.
I can repeat that it's not exactly what you asked and I know that compiling of ASP.NET source code could be also a little tricky, but I decided do write the information. If somebody would suggest you the better solution it would be interesting for me too.
I had exactly the same issue (correct version but no symbols), but after a day or so of trying everything I've been able to get it working. These are catch-all instructions that worked for me, they may contain unnecessary steps:
Sign up for SymbolSource and follow the VS instructions using the
authenticated URL form
Uninstall all versions of MVC with add/remove programs
Remove MVC assembly from the GAC (the question is about modifying
MVC but the GAC answer is good)
Remove and then reinstall the MVC 4 reference to your project with
NuGet
Start debugging, open the modules window, and cross your fingers
that ‘Symbols loaded’ is next to System.Web.MVC when it appears.
(sprinkle in restarts as you see fit, for me the key final step was reinstalling the NuGet reference)
My theory is that as the GAC library is used at runtime in preference to the local reference, the symbols are not found when they are searched for. By removing MVC from the GAC and then reinstalling the NuGet reference, it seems the local reference is used and the symbols are found. It's counterintuitive as the System.Web.MVC.dll files are binary-equivalent between NuGet and the GAC, although they are dated differently.
I'm not totally convinced though as I tried to do the same thing for Razor and that didn't work.
Let me start with that ReSharper provides a handy dialog to step in the code at any time:
So you get the following code screen if you drill to the source code:
But I became curious to accomplish this by hand. I started with proper pdb configuration:
After that I got the following error:
Next I copied the C:\Users\Andrew\AppData\Local\Temp\SymbolCache\MicrosoftPublicSymbols\System.Web.pdb\CA49C4332DE847FA967F58AFF370B70E1\System.Web.pdb to C:\Users\Andrew\AppData\Local\Temp\SymbolCache\System.Web.pdb (to match the lookup path). After that i encountered this:
And it turned out that the mismatching builds are only good for browsing the source, not debugging. (Current machine has VS2012 RC, hence MVC libraries are not RTM). If they match, you'll the the source.
I still don't know why doesn't the lookup path adjust to symbol configuration. Hope this helps.
I just solved this same problem.
The problem is that the dll stored in the GAC does not correspond exactly to the published pdbs on symbolsource.org. The one on symbolsource corresponds apparently to the latest version available through Nuget, and the one in the GAC must the one installed with .NET Framework 4.5. (.Net uses whatever is on the GAC before attemting to use anything local to your proyect, you can see this, when debuggin, go the Debug->Windows->Modules, there the System.Web.Mvc.dll is the one from GAC according to its path)
What I did was to include in the GAC the System.Web.Mvc.dll on the package folder of my solution, the one downloaded through Nuget. This you can do by using gacutil on a VS Command Prompt (run the VS Cmd as admin).
You can check on the same Modules Windows, right clicking on the System.Web.Mvc.dll, and then on Symbol Load Information. With the "old" GAC dll you get a message like (part of it)
SYMSRV: http://srv.symbolsource.org/pdb/Public/System.Web.Mvc.pdb/1E540B87149F4031B9CDEACAD8D771231/System.Web.Mvc.pdb not found
Notice here the subfolder 1E540B87149F4031B9CDEACAD8D771231 (yours might be different)
After replacing the GAC dll for the one recently downloaded through Nuget, the message is
SYMSRV: System.Web.Mvc.pdb from http://srv.symbolsource.org/pdb/Public: 336067 bytes
http://srv.symbolsource.org/pdb/Public: Symbols downloaded from symbol server.
C:\Users\\AppData\Local\Temp\SymbolCache\System.Web.Mvc.pdb\68B2330E48624B6C9DE05BED1C8C320F1\System.Web.Mvc.pdb: Symbols loaded.
Notice the subfolder 68B2330E48624B6C9DE05BED1C8C320F1, which is the one that is searched for in symbolsource.org is the correctly found.
Hope this helps

Why can't my .NET 4.5 project use a DLL compiled for .NET 4? (Both use EF 5)

I have an application that consists of a client-side application and a WebApi website.
My client-side stuff is targetting .NET 4 so that I don't have to insist that users install .NET 4.5. My website, however, is entirely under my control, so I'm targetting .NET 4.5.
There is one shared assembly, which I use for data access. It uses Entity Framework 5.
When I build the client application, the DLL used is version 4.4.xxx, whereas when I build the web application, the DLL is 5.0.xxx.
Up until now, I've been able to run the client application with no problems, and I've also been able to run the web application, again without problems.
However, I've now re-created my web application project from scratch (*), and suddenly I can't run it. I get a YSOD saying "Could not load file or assembly 'EntityFramework, Version=4.4.0.0 ..." at the point where my data-access assembly is first invoked.
Now, it's perfectly clear what that error means - it can't find the v4.4 DLL as used by the data-access assembly - but I don't understand why that's a problem with my new project when it wasn't a problem with my old project. As far as I can see, the same DLLs are referenced in each project.
(*) I should explain why I'm re-creating my project. I originally created the project in VS 2012 RC, and then later upgraded to the release version. Although this supposedly upgraded my project, I've had a few problems with it, and have also noticed some differences v. a newly-created project. So, to be on the safe side - and hopefully circumvent those other problems - I'm re-creating it from scratch.
So, my question: why is this suddenly a problem, and what can I do to resolve it?
Is the code depending on the assemblies set to require the exact version? If so, you will need a publisher policy for the EntityFramework assembly or bindingRedirect for the referencing application (web project).

How can I have two .NET projects in the same domain

I have two .NET projects in the same domain. The first project I create long time ago in VB.NET. Now I create another project that I built in C#. How can I set up my new project in the same domain so I can access the new forms that I built in C#. Do I need to submit the whole folder from the project? Do I need to change anything in the web.config? Right now I am getting this error. [PhoneControl] is the new project in C#.

If you look in the error page it says:

Version Information: Microsoft .NET Framework Version:1.1.4322.2407;
ASP.NET Version:1.1.4322.2407
And you are trying to use some .NET 3.5 components
Change the website to use .Net 2.0 and make sure the server have .NET 3.5 SP1 installed
