  MVC 3 - Compile Error MSB4184

  Sep 21, 2011 08:14 PM|LINK

  I do have 4 MVC3 projects. 3 of them I can compile without problem, but one of them gets the following compile error.

  C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v11.0\WebApplications\Microsoft.WebApplication.targets(352,50): error MSB4184: The expression "[System.String]::new()" cannot be evaluated. Attempted to access a missing method.

  Any ideas about what to do against this?

  Thankx, Harry

  From release notes,

  • Installing ASP.NET MVC 4 Developer Preview breaks ASP.NET MVC 3 RTM applications.ASP.NET MVC 3 applications that were created with the RTM release (not with the ASP.NET MVC 3 Tools Update release) require the following changes in order to work side-by-side with ASP.NET MVC 4 Developer Preview. Building the project without making these updates results in compilation errors.

    Required updates

    1. In the root Web.config file, add a new <appSettings> entry with the key webPages:Version and the value 1.0.0.0.

    <appSettings>
        <add key="webpages:Version" value="1.0.0.0"/>
        <add key="ClientValidationEnabled" value="true"/>
        <add key="UnobtrusiveJavaScriptEnabled" value="true"/>
    </appSettings>

    1. In Solution Explorer, right-click the project name and then select Unload Project. Then right-click the name again and select Edit ProjectName.csproj.
    2. Locate the following assembly references:

        

       <Reference Include="System.Web.WebPages"/> 
       <Reference Include="System.Web.Helpers" />

       Replace them with the following:

       <Reference Include="System.Web.WebPages, Version=1.0.0.0,
       Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL "/> 
       <Reference Include="System.Web.Helpers, Version=1.0.0.0,
       Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL" />

    3. Save the changes, close the project (.csproj) file you were editing, and then right-click the project and select Reload.
