ASP.
NET MVC 3 can be installed side by side with
ASP.
NET MVC 2 on the same computer, which gives you flexibility
in choosing when
to upgrade an
ASP.
NET MVC 2 application
to ASP.
NET MVC 3.
The simplest way
to upgrade is
to create a new
ASP.
NET MVC 3 project and copy all the views, controllers, code, and content files from the existing MVC 2 project
to the new project and then
to update the assembly references
in the new project
to match the old project. If you have made changes
to the
Web.config file
in the MVC 2 project, you must also merge those changes with the
Web.config file
in the MVC 3 project.
To manually upgrade an existing
ASP.
NET MVC 2 application
to version 3, do the following:
1.
In both
Web.config files
in the MVC 3 project, globally search and replace the MVC version. Find the following:
System.
Web.Mvc, Version=2.0.0.0
Replace it with the following
System.
Web.Mvc, Version=3.0.0.0
There are three changes
in the root
Web.config and four
in the Views\Web.config file.
2.
In Solution Explorer, delete the reference
to System.
Web.Mvc (which points
to the version 2 DLL). Then add a reference
to System.
Web.Mvc (v3.0.0.0).
3.
In Solution Explorer, right-click the project name and then select Unload Project. Then right-click again and select Edit ProjectName.csproj.
4. Locate the ProjectTypeGuids element and replace {F85E285D-A4E0-4152-9332-AB1D724D3325} with {E53F8FEA-EAE0-44A6-8774-FFD645390401}.
5. Save the changes and then right-click the project and select Reload Project.
6. If the project references any third-party libraries that are compiled using
ASP.
NET MVC 2, add the following highlighted bindingRedirect element
to the
Web.config file
in the application root under the configuration section:
<runtime>
<assemblyBinding >
<dependentAssembly>
<assemblyIdentity name="System.
Web.Mvc"
publicKeyToken="31bf3856ad364e35"/>
<bindingRedirect oldVersion="2.0.0.0" newVersion="3.0.0.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>
