upgrade/convert rdlc report files from VS2008 to VS2010 - visual-studio-2010

I have a report (rdlc) file made on VS2008 and can work on both Report Viewer 2008 & 2010.
Then I converted the rdlc report file to Report Viewer 2010 by using xmlns="http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition" and using <ReportSections> appropriately inside the file. (I did this because when I open the report file in vs2010 it didn't gave any alert for converting the file; so I thought I could do it manually.)
After that manual conversion, I continued using VS2010 with Report Viewer 2010 in my project but it gives me an error text : "The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition' which cannot be upgraded."
I'm sure that the Microsoft.ReportViewer.WebForms assembly is version 10 in my project references. And also I used the following configurations in config file
<system.webServer>
<handlers>
<add name="ReportViewerWebControl10" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" resourceType="Unspecified" />
<!--<add name="ReportViewerWebControl9" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" resourceType="Unspecified" />-->
...
</handlers>
...
</system.webServer>
...
<system.web>
<httpHandlers>
<add verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false" />
<!--<add verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false" />-->
...
</httpHandlers>
</system.web>
So what is the problem? How can I convert rdlc files from 2008 to 2010 for the best? And if the problem is not caused by the rdlc itself how can I fix this? Is there a way to show the conversion popup in vs2010 as described here?

VS 2010 misses "Microsoft.ReportViewer.Common Version=8.0.0.0" when running with SSRS 2012

Our project is built with VS 2010 and reports are built with SSRS 2005 and it works just fine, in this environment.
We are trying to migrate to SSRS 2012. In run time we get this error
'Microsoft.ReportViewer.Common, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
I copied the file "MicrosoftReportViewerCommon.dll" to the bin folder, but its version is 10.0.x.x. I don't know how to find version 8.0.0.0.
I don't know exactly what we should do. Is it supposed to add this file to the project? Or the references in the project should be changed to refer to another file version?? And how this should be done??
In the web form we have this line of code:
<%# Register Assembly="Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
and in web.config:
<system.web>
<httpHandlers>
<add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
validate="false" />
</httpHandlers>
......
</system.web>
<system.webServer>
<handlers>
<add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</handlers>
</system.webServer>
Any help is appreciated.
After 2 days of searching the web, I figured out how to overcome this error.
I had to install ReportViewer 2005, and this installer will register “Microsoft.ReportViewer.Common Version=8.0.0.0” in GAC automatically.
I've been told that is not a good practice and it is just a workaround, because the project is not running using the most updated controls and it is still using the old ones.
For now the project is working fine, but I hope some body provide me with a real solution.
I had a similar problem and found I needed three files:
Microsoft.ReportViewer.Common.dll
Microsoft.ReportViewer.ProcessingObjectModel.dll
Microsoft.ReportViewer.WebForms.dll
And the config file looked like this:
<assemblies>
<add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
<add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

ASP.NET Performance Profiling 404/500 errors

Using the Visual Studio Performance Explorer, with Cassini, I'm trying to launch profiling on my (Orchard CMS 1.4.0) ASP.NET MVC3 application, but I get this error:
The web site could not be configured correctly; getting ASP.NET process information failed. Requesting http://localhost:30320/OrchardLocal/VSEnterpriseHelper.axd returned an error: The remote server returned an error: (404) Not Found.
So I searched for a solution and found this article which didn't apply, because I'm using Visual Studio's development server (Cassini) not IIS - no less IIS 6. Then I read this article and this article; of all those suggestions, the only one that made a difference was adding the location section to my web.config, to grant access to VSEnterpriseHelper.axd. But as one of those articles predicted, my 404 error simply became a 500:
The web site could not be configured correctly; getting ASP.NET process information failed. Requesting http://localhost:30320/OrchardLocal/VSEnterpriseHelper.axd returned an error: The remote server returned an error: (500) Internal Server Error.
The trailing commentaries in these various articles aren't working for me. Any suggestions? I figure I will post my (Orchard 1.4.0) web.config here, in case somebody can spot a culprit:

In my case, I had

set in my web.config. When I changed it to
<validation validateIntegratedModeConfiguration="false" />
things magically started working. Three hours down the drain....
I faced similiar problem, and I found one solution. I found out that I get 404 error because VSEnterpriseHelper.axd is routed through MVC, and it's happening whatever I set in Web.config. So I figured out that I should route it properly. So I added route to handle this file, and I wrote handler:
Handler:
public class DefaultRouteHandler : IRouteHandler
{
public IHttpHandler GetHttpHandler(RequestContext requestContext)
{
return new DefaultHttpHandler();
}
}
internal class DefaultHttpHandler : IHttpHandler, IRequiresSessionState
{
public void ProcessRequest(HttpContext context)
{
string contentPath = context.Request.PhysicalPath;
#if DEBUG
if (contentPath == context.Server.MapPath("VSEnterpriseHelper.axd"))
{
var assembly = AppDomain.CurrentDomain.GetAssemblies().SingleOrDefault(a => a.GetName().Name == "Microsoft.VisualStudio.Enterprise.AspNetHelper");
if (assembly == null)
{
if (File.Exists(#"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Enterprise.AspNetHelper.dll"))
{
assembly = Assembly.LoadFrom(#"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Enterprise.AspNetHelper.dll");
}
if (File.Exists(#"C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Enterprise.AspNetHelper.dll"))
{
assembly = Assembly.LoadFrom(#"C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Enterprise.AspNetHelper.dll");
}
}
var type = assembly.GetType("Microsoft.VisualStudio.Enterprise.Common.AspNetHelperHandler");
var handler = (IHttpHandler)Activator.CreateInstance(type);
handler.ProcessRequest(context);
return;
}
#endif
[...]
}
}
Route definition:
DefaultRouteHandler defaultHandler = new DefaultRouteHandler();
routes.Add(new Route("{*resource}", new RouteValueDictionary(), new RouteValueDictionary(), defaultHandler));
I fixed the same 500 error, here is what you need to do (partially borrowed from here with my own comment):
Make sure you have write permissions on your web.config file
If your website has locked down security on the root folder (using either
forms or windows authentication etc), make sure you add a [location] tag to allow full access to the vsenterprisehelper.axd file, like this:
<location path="VSEnterpriseHelper.axd">
<system.web>
<authorization>
<allow users="?" />
</authorization>
</system.web>
</location>
Ensure AXD extensions are configured in IIS for your site
There are problems if your AppSettings are stored in a separate configuration file, and your web.config refers to them with a configSource attribute
I finally (4 hours later) fixed this by moving my default .axd route handler from RouteConfig.cs into the main Global.asax.cs:
AreaRegistration.RegisterAllAreas();
// Register .axd route ahead of WebApiConfig
RouteTable.Routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
GlobalConfiguration.Configure(WebApiConfig.Register);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
Because I was using WebAPI, the WebApiConfig routes were picking up the calls to the AXD as they were being registered before RouteConfig.RegisterRoutes where the .axd exception is by default.

ReportViewer 11 (2012) Visual Studio 2010

I am using Visual Studio 2010 and I installed "Microsoft Report Viewer 2012 Runtime" hoping to test the new reporting system in SQL 2012. After which I cleared for ref to "Microsoft.ReportViewer.WebForms" from my Web.config and removed the ReportViewer control from my toolbox and added the new version 11 ReportViewer.
I added the new control to a testing page and for one it adds this register to the test page:
<%# Register Assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
and it adds these entry to the Web.config:
<buildProviders>
<add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</buildProviders>
<httpHandlers>
<add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false" />
</httpHandlers>
<handlers>
<add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</handlers>
The control in the toolbox is the version 11 addition but the system keeps trying to ref the verion 10 edition. Also when I try to compile it I get the error:
The type 'Microsoft.Reporting.WebForms.ReportViewer' exists in both 'c:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.WebForms\10.0.0.0__b03f5f7f11d50a3a\Microsoft.ReportViewer.WebForms.dll' and 'c:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.WebForms\11.0.0.0__89845dcd8080cc91\Microsoft.ReportViewer.WebForms.DLL'
I think I had the exact same problem. If so, my solution was to delete all entries in web.config referencing ReportViewer, then do the same in References, build the project and then re-ADD a reportviewer in the page.
web.config will update with new handlers and assemblies for the newer version.
I had the same error, and resolved it by doing the following:
In the aspx page (HTML code), updated the #Register Version value to correspond to the version of the assembly I was using, and updated the PublicKeyToken value with the correct value for the assembly.
In your web config, it means you have specified both v 10 and 11 dlls. Remove one or the other.
I have removed the following entry from package.config and it works
<package id="MicrosoftReportViewerWebForms_v10" version="1.0.0" targetFramework="net45" />

The name 'model' does not exist in current context in MVC3

I added a cshtml page in an project. When I tried to add the following declaration to it, I get an error: "The name 'model' does not exist in current context".
#model xyz.abc.SomeClass
I checked the references, all of them are in place. I added a web.config in view folder, but that didn't fix it.
Is there anything i am missing?
Update: If you are using a newer version of MVC, the same process applies, just be sure to use the correct version number in the web.config's <host> line.
Well, I found myself experiencing the same thing you did, and after a bit further research, I found out what the problem is!
You need to include the default MVC3 web.config for the Views folder. MVC3 has two: one in the root for your application, and one for the views folder. This has a section for included namespaces. Be sure that yours looks something like this:
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
</namespaces>
</pages>
</system.web.webPages.razor>
I suggest that you create a new MVC3 project, then just copy the web.config created for you into your views folder.
Important Once you've done that, you need to close the file and reopen it. Voila! Intellisense!
I ran into this same issue when I created a new area to organize my pages. My structure looked like:
WebProject
- [] Areas
- [] NewArea
- [] Controllers
- [] Views
- [] Controllers
- [] Views
- Web.config
- Web.config
The views created in the Views folder under the WebProject worked fine, but the views created under the NewArea threw the following error:
The name 'model' does not exist in the current context.
To fix this I copied the web.config in the Views folder under the WebProject to the Views folder in the NewArea. See below.
WebProject
- [] Areas
- [] NewArea
- [] Controllers
- [] Views
- **Web.config**
- [] Controllers
- [] Views
- Web.config
- Web.config
I ran into this because I manually created this new area using Add -> New Folder to add the folders. I should have right-clicked the project and selected Add -> Area. Then Visual Studio would have taken care of setting the area up correctly.
If your views are in a class library assembly, which is useful for reuse of shared views among projects, then just doing what Adam suggests might not be enough. I still had issues even with that.
Try this in your web.config in the root of your project:

This worked for me. I now have intellisense and no compile errors on my views in a non-MVC project that I can then reference from multiple MVC websites.
I ran into this problem when I inadvertently had a copy of the view file (About.cshtml) for the route /about in the root directory. (Not the views folder) Once I moved the file out of the root, the problem went away.
Had similar problems using VS2012 and VS2013.
Adding the following line to <appSettings> in the main web.config worked:
<add key="webpages:Version" value="3.0.0.0" />
If the line was already there but said 2.0.0.0, changing it to 3.0.0.0 worked.
Update: 5/5/2015
For your MVC 5 project you need to set the Version to 5.0.0.0 in your /views/web.config
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</system.web.webPages.razor>
While you declare the model at the top of the view using code like this:
#model MyModel
you need to capitalise your references to it below, for example:
#Html.Encode(Model.MyDisplayValue)
I believe a missing web.config in the Views folder would be the major cause of this, but if that is fixed and the problem still persists, check that you are using Model, not model to refer to it in the source.
I ran into this problem as well. My circumstances were a little different.
One of my view folders was accidentally moved to my project's root directory. This lead to the route
project_root/SignUp/ViewName matching before project_root/Views/SignUp/ViewName. This caused the #model error.
After moving the views back into the appropriate location, the directory was somehow recreated in the project root. This time, empty. /SignUp/ViewName worked, but /SignUp/ threw a 403 - Forbidden: Access is denied. error. The entire folder must be removed from the project root.
I hope this helps someone. I spent hours believing the problem was caused by our recent upgrade from MVC 3 to MVC 4. Just a note: Upgrade problems should only occur between MVC 2 and MVC 3. If you see this problem on later versions, it's probably not due to the upgrade.
It took me ages to solve this issue, but finally I hope I have solved it on MVC, that is similar:
I have reinstall ASP.NET 4.5 (http://www.asp.net/downloads)
I have followed the upgrading tutorial on http://www.asp.net/whitepapers/mvc4-release-notes
BUT this mentioned paragraph is wrong for me
System.Web.Mvc, Version=4.0.0.0
System.Web.WebPages, Version=2.0.0.0
System.Web.Helpers, Version=2.0.0.0
System.Web.WebPages.Razor, Version=2.0.0.0
Because I have Razor in System.Web.Razor, so I changed the razor namespace to System.Web.Razor.
Add this to your web.config
<appSettings>
<add key="webpages:Version" value="2.0.0.0" />
</appSettings>
I have add the assembly reference to all these assemblies above
Locate the ProjectTypeGuids element and replace {E53F8FEA-EAE0-44A6-8774-FFD645390401} with {E3E379DF-F4C6-4180-9B81-6769533ABE47}.
That is all.
It is a horrible mistake but:
Be sure you have Web.config files in your View at Remote. Maybe you skipped to upload it by your Ftp programme's filters.
I was missing web.config under Areas/MyArea/Views/web.config. Once added it worked fine. This was with MVC 5 and .NET4.5
There is also another reason. In my case, I had copy an index.cshtml file to web root folder (outside the Views folder) as a backup from remote server.
So, I kept changing my /views/web.config, kept changing my /views/home/index.cshtml and error kept happening... until found out the /index.cshtml outside the views folder, deleted it and sure, it all went back to normal!
I ran into this same problem, but in my case, the only thing that had changed is that I had uninstalled Visual Studio 2012 and installed Visual Studio 2013. I opened up our solution, but I kept getting the same The name 'model' does not exist in current context error in every Razor view.
My coworker suggested checking for updates for VS2013. After I installed the VS2013 Update 1, I stopped getting this error.
Check your config file on views directory. in the
add the key for MVC 4/5
Reinstalling the nuget solved it for me
PM> Install-Package Microsoft.AspNet.Razor -Version 3.2.3
For me this was the issue. This whole block was missing from the section.

I've got the same issue after updating packages. I did the whole stuff You've written above in this topic, but the red underlying of the model keyword has not disappeared. Later, found solution: just deleted 'package' folder from my project's dir and rebuilded, in the meantime allowed NuGet to restore missing packages. Refreshed, and it's done!
Check your web.config file should be exist in published files
I was facing the same issue and then I find a solution. The solution is:
Close Visual Studio
Delete the SUO file
Restart Visual Studio
The .suo file is a hidden file in the same folder where the .svn solution file exists. Hope, it'll work!
Closing Visual Studio and re-opening worked for me. Must be a weird bug.

Visual Studio 2010, Linq extension methods and framework 3.5

If I set <compilation targetFramework="4.0"> in web.config, Visual Studio 2010 shows all Linq extension methods in ASPX files (not codebehinds). But when I change my project to target 3.5 (which supports Linq extension methods) Visual Studio removes the previously mentioned attribute in web.config, but Linq intellisense in APSX files goes with it as well.
Question
Is it possible to convince Visual Studio 2010 to not assume and fall back to 2.0 when editing ASPX files, so Linq extension methods would still be listed in intellisense dropdown?
Edit
Manually adding assemblies and import namespaces doesn't do the trick as I've pointed out in one of my previous questions, when I didn't know what was going on.
Problem reproduction
To reproduce this issue do the following:
In Visual Studio 2010 open Asp.net MVC project properties and target NetFx 3.5
Open web.config and remove targetFramework attribute if it's still there.
Write some code in the view itself (ASPX) that uses Linq extension method (ie. (new List<string>()).Any(s => string.IsNullOrEmpty())). You should see that Any is not recognised by Visual Studio 2010.
Start adding one configuration setting by one in web.config. There should be no difference about Any method.
Add <% # Imports ... %> to the view. There should be no difference about Any method either.
Running the application is not a problem. It runs and it also executes Any Linq extension method. No problem with that. Design time support is the issue here.
My web.config file
This is the complete content of my web.config file, that doesn't do the expected (I can include commented out parts as well, but that doesn't make any difference - original Asp.net MVC 2 project template doesn't include these either):
<?xml version="1.0"?>

This is how it looks like in Visual Studio 2010. In the image you can't see the extra line <%# Import Namespace="System.Linq" %> that should be right after <%# Control ... %>, but I've tried with and without. system.web/pages/namespaces is the global setting for this anyway.
The root web.config for .NET 4.0 has System.Linq added to system.web/pages/namespaces. This is not the case for .NET 3.5 which, although it includes the Linq library, did not introduce changes to the root web.config for backwards-compatibility reasons, so you have to add it to the system.web/pages/namespaces in your web.config.
See ASP.NET Configuration File Hierarchy and Inheritance
I think it's because LINQ is assumed to be included in the 4.0 framework. For older versions, you can manually import the LINQ namespace by adding this to each ASPX page at the top:
<%# Import Namespace="System.Linq" %>
Or if you don't want to do that in each file, you can put it in your web.config.
Edit - As has been pointed out by others, your problem may come from the fact that you have System.Core commented out of your web.config, which is required for those extension methods.
Including System.Core assembly is of course important. But doesn't do anything is you don't also do this next thing.
To make everything work in Visual Studio 2010 as expected (and under framework 3.5) you have to add <system.codedom> configuration element in web.config as well. This is the part that was missing:
<system.codedom>
<compilers>
<compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4">

<providerOption name="WarnAsError" value="false"/>
</compiler>
</compilers>
</system.codedom>
