I have a very peculiar issue using Azure Table Storage. I have a .NET 4.5 project in Visual Studio 2012 where I deal with all my Azure Table Storage functions. This project/dll is referenced by two other projects, my MVC website, and my Azure Worker Role. (I am running under the Azure Emulators on my machine, but it also happens when I deploy it to the cloud)
I have the following function that is called when I save or retrieve a record:
internal static CloudTable GetTable(CloudStorageAccount storageAccount, string tableReference)
{
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
CloudTable table = tableClient.GetTableReference(tableReference);
table.CreateIfNotExists();
return tableClient.GetTableReference(table.Name);
}
In my MVC website I have a function that will save a record to a Azure Storage table, and then in my Azure Worker Role there is a service that will read the record.
So both uses the same dll for storage and retrieval, however my MVC project has no issues saving the record, but in my Azure Worker role service when it tries to retrieve the record throws the exception when it attempts to execute "table.CreateIfNotExists();".
Could not load file or assembly 'Microsoft.Data.OData, Version=5.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
I have done the following already:
I have not rolled the dll's back to 5.2 as I had too many issues in other projects where I use features that are specific from 5.3 onwards.
I am currently running all the dll's on 5.5.
When I run the AsmSpy.exe utility found here, I get the following output that I am not 100% sure how to interpret.
> Reference: Microsoft.Data.Edm
> 5.5.0.0 by Microsoft.Data.OData
> 5.5.0.0 by Microsoft.Data.Services.Client
> 5.5.0.0 by Microsoft.WindowsAzure.ActiveDirectory.GraphHelper.2013_04_05
> Reference: System.Spatial
> 5.5.0.0 by Microsoft.Data.OData
> 5.5.0.0 by Microsoft.Data.Services.Client Reference: Microsoft.Data.OData
> 5.5.0.0 by Microsoft.Data.Services.Client
> 5.2.0.0 by Microsoft.WindowsAzure.Storage <-- THIS SEEMS TO BE THE ONE THAT IS CAUSING ISSUES
How I interpret it, is that the Microsoft.WindowsAzure.Storage dll is referencing V 5.2.0.0 of the Microsoft.Data.OData dll, but how do I fix this, if this is the issue? According to the documentation I have seen on the Storage dll is that it is supposed to reference 5.4 and up, not 5.2...?
Opening issue for such an easy to solve issue will not help you.
Put the following addition configuration in your respective config files (web.config for the MVC and app.config for the worker role):
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Microsoft.Data.OData" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.5.0.0" newVersion="5.5.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="Microsoft.Data.Edm" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.5.0.0" newVersion="5.5.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
Note that runtime
section is direct descendant of the configuration
root element! I'm pretty sure you already have this section in your web.config, because MVC4 uses it to rebind all references to System.Web.MVC
to the latest version.
I personally do not expect the SDK to be updated with every new version of every referenced library! This would be madness...
