I have Made My application in Visual Studio 2008,It works Properly On IIS7 If i have installed AspNetMVC3.But not worked without this software on any other machine.
// This is Error
<system.web>
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
//End of Error
</script>
Ist there a chance that you have not the right target frame work activated on IIS? I asume that your application wants .Net Framework 4 and your have .Net 2.0 / 3.0 or 3.5 actived...
Just a guess... like the others said please provide more information... =)
Here is a link how to install .Net 4

Edit:
check out this question and answer for very detailed information
How to add ASP.NET 4.0 as Application Pool on IIS 7, Windows 7
Check that you have the HttpMpdule. Go to IIS Manager > Default Website click it. In the right pane double click Modules and verify that you have this module. If it is missing then you cannot run asp .net mvc even in integrated mode

First, I update the VS 2019. After that I updated my project from .net framework 4.6 to 4.8.
Now I getting the Intelligence error in the MVC view. I check some article and blog related it and try below points for it.
Delete the bin and obj folder.
Delete .vs file
Delete the packages folder.
I did all things but still I am getting the same Intelligence error.
I was getting the same error after the framework upgrade. Need to add System.Core reference in the main Web.config file.
<compilation>
<assemblies>
<add assembly="System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
</assemblies>
</compilation>
I've created a WebSite Project in Visual Studio 2019, but when I try to add an ADO Entity Model and I click on New COnnection, Visual Studio raise an error:
assemblyFile is null or empty
at Microsoft.Data.Entity.Design.VisualStudio.ExecutorWrapper...
After clicking on Abort, the only button that can close the error window, VS crashes.
I've tried to reinstall everything from scratch several times, I've installed also on another PC but the error persists.
The reference to the assembly System.Data.Entity is in the webconfig:
<compilation debug="true" targetFramework="4.7.2">
<assemblies>
<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
<add assembly="System.Data.Entity.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
</assemblies>
</compilation>
Anyone knows how to solve or Database first in EF6 must be forget??
This happen to me on a website project. I change it to use Web Application project and now EF works fine. Try that.
Hi I have a project which is Web application and use .Net Framework 4.5. I can debug some projects in VS2015, but some project I am unable to debug. I checked the web.config and it shows it can be debug. It should not be Firewall issue because the other web application can debug. I searched the web and tried many methods and didn't solve. Would someone tell me how to solve.
<compilation defaultLanguage="vb" debug="true" targetFramework="4.5.1" />
There is an error message:
There is my property
When I open a solution containing an MVC3 project in Visual Studio 11 Beta, I see the following message:
The Web project 'Landboss.Web' requires missing web components to run
with Visual Studio. Would you like to download and install them using
the Web Platform Installer now? (Note: Some components might require
restart to take effect.)
ASP.NET Web pages with Razor syntax 1.0.0.0
When I click Yes, the Web Platform Installer opens and tells me this:
The product you are trying to install is not supported on your
operating system. Click here for more information.
So far I've installed Visual Studio 11 Beta on two machines and both have this same problem.
I believe this was caused by the fact that I had previously installed Visual Studio 11 Developer Preview. I did uninstall it before installing the Beta, but you know how that goes.
To fix it, I did the following:
Uninstalled "Microsoft ASP.NET MVC 3 - Visual Studio 11 Tools Update"
Uninstalled "Microsoft ASP.NET Web Pages - Visual Studio 11 Tools"
Ran the Visual Studio 11 Beta "Repair" from the installation ISO.
It worked! Razor syntax highlighting and intellisense are back, and the warning message no longer shows when I open the project.
This is related to the configuration setting webpages:Version
[appSettings]
...
[add key="webpages:Version" value="x.0.0.0" /]
...
[/appSettings]
if you have multiple versions of razor on the system (1 or 2 for now), better add this setting if it's missing.
Choose the version you want/need at the appropriate level. (Obviously replace the brackets...)
I have also had this error happen when a Subversion conflict was committed to the repository - the presence of this block in the web.config's app settings seemed to trigger the message when loading the project:
<<<<<<< .mine
<add key="blogCommentsApprovedByDefault" value="false" />
(other appsettings)
=======
<add key="blogCommentsApprovedByDefault" value="false" />
(other appsettings)
>>>>>>> .r358
Cleaning up the Subversion conflict in appSettings resolved this error.
While #silent__thought's solution may correct the problem, it's not the easiest way to fix it.
#Costas solution may exactly address the problem, but here is a more detailed explanation if you need it.
In my case, I needed the following in my web.config file (for MVC 4):
<configuration>
<appSettings>
<add key="webpages:Version" value="2.0.0.0" />
<add key="webpages:Enabled" value="false" />
<add key="PreserveLoginUrl" value="true" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<pages>
<namespaces>
<add namespace="System.Web.Helpers" />
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<add namespace="System.Web.WebPages" />
</namespaces>
</pages>
<httpHandlers></httpHandlers>
</system.web>
</configuration>
Of course, you may not need all of these configurations for your app. These just happen to be the default settings for an MVC 4 project.
I got this error because the appSettings section was setup to be encruypted, and the encryption keys were not setup correctly. It seems this error has a tendancy to popup whenever there is something wrong/malformed with web.config even if unrelated to MVC.
I got this error when something in the web.config file was corrupted. I simply formatted the file and then resaved it. Then I restarted Visual Studio.
I've just been bitten by this and it's another variation of the web.config problem. In my case we do not store a web.config file in our repo but generate one from a template as a custom build step. When we do a clean of the workspace* this file was being deleted (rightly so because it's not in the repo) and so the next time Visual Studio was started it complained. A command line build via msbuild was never affected by this.
*We have a "partial" clean, which deletes all the build artefacts (including those VS leaves behind) and a "full" clean that resets the workspace to the same state as if you had just pulled it from the repo.
I've been trying to implement the wonderful SqlCe 4.0 Membership Provider by ErikEJ but I'm having trouble. I got it working via the documentation mr EJ provides. But....
I want to abstract the source into an external DAL. But I'm having issues getting there. The first problem I'm getting is trying to add the reference to SqlCe via the .csproj file rather than the web.config. (I need to do this so I can add the same reference in my DAL project) (I also need to be able to set copy local to true so want it in the csproj references). So I do this....
<assemblies>
<add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<!--<add assembly="System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91"/>-->
</assemblies>
And then add it in my project...
But when I browse to the website I get this error message:
Unable to load the native components of SQL Server Compact
corresponding to the ADO.NET provider of version 8482. Install the
correct version of SQL Server Compact. Refer to KB article 974247 for
more details.
When I refer to the KB article it says:
FIX: You receive an error message when you run a SQL Server Compact
3.5-based application after you install the 32-bit version of SQL Server Compact Edition 3.5 Service Pack 2 on an x64 computer
And yeah that's whats throwing me. Why is it talking about 3.5? I have added a reference to the 4.0 dll which Eric's provider is designed to work with.
I really hope someone can help. Perhaps Erik will read this post :-)
p.s. I'm also wondering what the difference between adding a reference in the web.config and adding it it via the csproj actually is. I thought it was because the web.config looks in the GAC. But when I try to add a reference in visual studio (to the csproj) i cant see the option to add System.Data.SqlServerCe at all!
I can also say that when I copy the dlls directly from
C:\Program Files\Microsoft SQL Server Compact Edition\v4.0\Private
Into my DAL bin and website bin and reference them directly in the CSproj I still get the same issue.
You are using the Private assembly version (4.0.0.1) - sounds like the required unmanaged DLL files are missing from your deployed site. Could you have a look in file explorer and show what you see.
Also, see this SO answer: Can't get sql server compact 3.5 / 4 to work with ASP .NET MVC 2
