Issue with MVC 5.2

[ghost]

Hey Andrew,

Our project is using Postal 1.0.0.0 for MVC5 and since updating to System.Web.Mvc 5.2, it all stopped working. This is in my assembly binding Fusion log:

=== Pre-bind state information ===
LOG: DisplayName = System.Web.Mvc, Version=5.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35
 (Fully-specified)

WRN: Comparing the assembly name resulted in the mismatch: Minor Version
ERR: Failed to complete setup of assembly (hr = 0x80131040). Probing terminated.

I have my binding redirects setup correctly under my web.config:

<dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-5.2.0.0" newVersion="5.2.0.0" />
</dependentAssembly>

No other components have this issue except for Postal. I noticed the dependency for Postal for MVC5 is >= 5.1.2, so 5.2 should be working, but Postal is somehow requiring 5.1.x.x specifically.

Any ideas?

Is Postal's reference to MVC incorrect? The following is copied from Postal.Mvc5.csproj:

<Reference Include="System.Web.Mvc, Version=5.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
    <SpecificVersion>False</SpecificVersion>
    <HintPath>..\..\packages\Microsoft.AspNet.Mvc.5.1.2\lib\net45\System.Web.Mvc.dll</HintPath>
</Reference>

SpecificVersion is false! Perhaps I'm misunderstanding something here. Do I really have to release a new version of Postal for every minor update to MVC?

I had the same problem today. I still haven't figured it out. But it only happens when there a class that inherits from Email (ie, a "Strongly Typed Email") is in my project. I tried creating a new sample project to re-create the issue, but so far no luck. I started out with Postal 1.0, but I'm currently on the latest release.

Ghost, were you using strongly typed emails by any chance? And did you ever work this out?

I am having issues with Postal as well after upgrading Razor to 3.2.2 and MVC to 5.2.2

I ran into the same issue using a class that inherits from Email. After trying a plethora of fixes, switching the build config from using Visual Studio 2012 to 2013 resolved the issue.

i'm having the same problem. i have postal running in a service. strongly type. i have mvc 5.2.3 in this project and i can not use @Html.Raw() to decode my html @Model.Message. i've tried Reference Including 5.1.0.0 but this caused more problems by only resolving by nuget downgrading and upgrading my mvc. postal is a great project. but can you please resolve this problem?

Postal stopped development?
