So, Here is the actual issue. I have created a sitefinity project through Sitefinity Project Manager and after running it, i open the project files into my visual Studio 2019. I checked till here that everything is working fine and it was. Now when i go for installing Ucommerce on the project through Nuget packages. The package is Ucommerce.Sitefinity after installation it simply throws this error whenver i run it. Even when i removed the package the problem was still there.
Its like the Ucommerce package corrupts the project completely.. I have tried resolving it by searching on the internet but somehow it seems the solutions which worked for others are not for me as my project is not a simple asp.net project rather a sitefinity project, I may be wrong. Most of the solutions which i tried are from this thread here : Could not load file or assembly 'Newtonsoft.Json' or one of its dependencies. Manifest definition does not match the assembly reference But as i said all in vain. Please help me with this as i need to get started with my development on the ucommerce for a project. Thanks in advance.
Also After removing the nuget package the Values for the Version changed from 6.0.0.0 to 12.0.0.0 .
Try manually deleting all files from the bin folder and then build again.
Probably there was an assembly that referenced an old version of the newtonsoft dll.
Finally, check the runtime bindings in web.config for the version of newtonsoft dll there.
Make sure it points to the version that is inside your packages.config file.
When I install Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation in a Web project and in Startup add :
services.AddMvc().AddRazorRuntimeCompilation();
,the project does not run and the error is:
the project must provide a value for configuration
my .NET-Core version is 3.1
How can this be fixed?
There are some GitHub issues with this problem and some solutions that have worked for people. That said I would check to see that all NuGet packages are on versions supported by .NET Core 3.1. At this particular moment that means not too new so as to only work with .NET 5 and not too old so as to only work with Core 2.2.
Otherwise, someone suggested restarting VS.

You may also try deleting Microsoft.AspNetCore.Razor.Design from the CsProj file per this duplicate question
I just installed Ninject.MVC5 into my solution (I have an MVC project and a WebApi project in there and I wanted Ninject for both).
Then I installed WebApiContrib.IoC.Ninject to build on the previous install so that I could use Ninject in the WebApi package.
Then I updated the packages (because NuGet showed updates to install - even though I had updated the packages directly prior to installing Ninject).
I tried running my WebApi project but it failed on var kernel = new StandardKernel(); in NinjectWebCommon.CreateKernel() with this error:
An exception of type 'System.IO.FileNotFoundException' occurred in Ninject.dll but was not handled in user code
Additional information: Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
Having read several answers on here and contemplated certain relatively complex solutions I tried one more thing which I will share in the Answer in case it helps anyone else...
I removed WebApiContrib.IoC.Ninject from the WebApi project (via NuGet: Manage and then untick to remove) and then added it back.
Project runs and behaves as expected, and no updates are required after adding WebApiContrib.IoC.Ninject back in to WebApi project.
The update that NuGet identified as required overwrote/broke something that was fixed by this answer.
Add the package Microsoft.Aspnet.Mvc from Nuget.
Solved for me.
In my case, MVC4 for Framework 4.0 and Visual Studio 2017
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
There's some related info here: http://aspnetwebstack.codeplex.com/discussions/399312
And here: Debug into nightly build of ASP.NET MVC4 using Symbolserver
I just NuGetted ServiceStack.Redis 3.1.3 but as its dependencies it also gets ServiceStack.Common and ServiceStack.Text 3.1.6
Now when I build the application everything is OK.
But, when I run the application some of the Redis Client methods execute properly but some of them e.g. (RedisClient.GetAllKeys) gives throws the exception
Could not load file or assembly 'ServiceStack.Common, Version=1.0.4336.27526, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
Then i removed all the dll's and nuget packgage config, and explicitly did a NuGet ServiceStack.Common -Version 3.1.3 and got it. But then when i tried to NuGet ServiceStack.Redis -Version 3.1.3 it automatically removed the 3.1.3 version of Common and downloaded the 3.1.6 version !!!
Arrrghhh, I hate over intelligent installers.
How do I fix this ?
Does the publisher of ServiceStack even know about this issue ??
Ok ! Found the Issue.
I was trying to use ServiceStack from a console application and it was configured to build in "ClientProfile" mode.
ServiceStack internally references System.Web which wasn't being accessible at runtime.
I switched the Application to Build using the full framework mode and everything works ok now.
Thanks anyways mythz !
Nope, ServiceStack was not aware of this issue. Though we'd like to know what's causing it.
I've tried a fresh install of ServiceStack.Redis and it works as expected.
To remove your dlls you need to go into NuGet package manager and finding the installed ServiceStack.Redis Package and clicking un-install. This should ensure the next install of the Project downloads it from the NuGet website and doesn't re-use your dirty dll cache.
Failing that ensure you have the latest version of NuGet and that your old NuGet caches are cleared. i.e. find and delete the NuGet /packages folder.
