Compilation Error
Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.
Compiler Error Message: The compiler failed with error code -2146232576.
Clean and Rebuild your solution (under Build menu). If it gives you any compilation errors, correct them and build it again. That worked for me.
Edit 3/12/18
It seems like you have read, or possibly write, locks on one or more files. Close the studio and verify that the source code repository don't have orphaned read/write locks. Also verify that any directories used for compilations don't have read locks. There used to be a weird Temporary ASP.NET-folder that was prone to locking files in the good old days.
Previous response
These are a few things that come to mind in my experience. I am assuming the deployment machine is a Windows Server of sorts.
Check the expected .NET version by checking project properties in Visual Studio (or the Project-files if another editor is used).
Compare with the installed version of .NET of the deployment machine. Framework on the deployment machine should equal to or greater than .
Verify the chosen app pool is running the expected version (or change it) and recycle it.
Make sure all the necessary assembly files (.DLLs) have been included on the deployment machine. A quick look into the BIN or DEBUG folder usually tells the story, but will generally also contains a whole lot more stuff. Sometimes too many assembly files removed during optimisation of the build.
A little bit of information about deployment OS and .NET versions would help.
I have create a sample ASP.NET 5 application (pretty much the example one from New Solution), and pushed it to GIT hosted on Visual Studio Team Services (former Visual Studio Online). I want to set up continuous integration to Azure Web App (former Azure Web Site). I have tried to set it up from Azure portal itself, it did create a new build definition, but it fails to build ASP.NET 5. I have found a guide how to do this, but it never really worked for me, I get errors like this e.g.
Error parsing solution file at C:\a\1\s\Frontend\src\Frontend\Frontend.xproj: Exception has been thrown by the target of an invocation.
Predefined type 'System.Void' is not defined or imported
Another problem is that it seems it really takes a lot of time to install dnvm, get packages, etc. So all in all it's a pain to make it work.
So are there real alternatives for that or more importantly is Microsoft is planning to implement something like a Build ASP.NET 5, Deploy ASP.NET to Azure and such to make it easy as I suppose it's easy with the current ASP.NET 4 apps. I really hope that it will be an option soon since it's quite impossible to work with current build system.
For "System.Void" issue, please check the runtime version in "global.json" file and make sure it is consistent with the dependencies in "project.json" file.
For dnvm install issue, since AspNet5 runtime environment isn't installed on VSTS Hosted Build Agent for now and the different users may use different runtime versions, it requires the user to add a "PreBuild" PowerShell step to read the runtime version in "global.json" file and then install it. If you can make sure that you will always only use one version (For example: 1.0.0-rc1-update1), you can deploy your own build agent and install "1.0.0-rc1-update1" on it, then you can skip the dnvm installation during the build process.
Take a look on http://riffer.eu/wordpress/?p=112. There I have a solution vor asp.net core RC_1.
Amazingly you need only two powershell scripts - there is no compiling / visual studio necessary.
Short introduction
My goal is to get IIS 8 to run an asp.net 4.5 website. Currently I have a CI server that pulls from version control and builds the web application with MSBuild.exe with this line of code
C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe C:\project\WebApplication\WebApplication.csproj /T:Package
The problem
The problem I am facing is that I dont understand why things like Controllers, Viewmodels, Models etc. that are pure C# code are being ignored or skipped when the project is being built with MSBuild.exe and packaged.
The package that MSBuild.exe returns only contains
Areas
bin
Content
fonts
Scripts
Views
and is missing many folders including
Controllers
Models
etc.
Questions
Is this normal?
Why does this happen?
What am I doing wrong?
Seems to be
No idea, but the functionality of the cs files is now probably part of dll's in the bin folder.
I was not doing anything wrong. I just thought this was a problem. I managed to get the asp.net web application to work on the web server like it does on the developer machine.
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

Has anyone had success making an msbuild file that will publish a Web Application, not the old 2.0 web site but a Web Application?
This is not what I am looking for:
<MSBuild Projects="eRx.Web.SecureSiteShell.csproj" Properties="Configuration=Debug;OutDir=$(OutputFolder)\$(OutputWeb)\bin\;WebProjectOutputDir=$(OutputFolder)\$(OutputWeb)\" Targets="ResolveReferences;_CopyWebApplication" />
I tried simply using 'targets:Publish' but I get : Skipping unpublishable project.
Apparently this just isn't possible. My first hint was getting absolutely no response from this site.
I began to look into making a web setup project but was unsatisfied at having to edit the installation dialogues to get a custom installation folder. All I really need is something that will copy the published output of a Web Application (not Web Site you 2.0 peeps).
I think I have cheated the system by creating a simple Windows Setup program. Surprisingly I am able to include the primary output of my web application which satisfies my need. I DO have to manually add each projects debug symbols if I want them so the process can be lengthly but doable.
Like I said, not completely satisfied because I wanted to get the files in a nice deploy folder for my QA group to work with but feeding them an MSI has its advantages I suppose.
I leave this for anyone to comment on. I still can't believe I can't do this from msBuild or any other tool.
