Sysytem.EntryPointNotFoundException in Microsoft.Windows.Azurestorage.dll version 6.0.0

Question

I am using Microsoft.WindowsAzure.Storage.dll version 6.0.0 for working with Azure table storage. While adding a new entry in the table, I am getting following error.

Line of code throwing error:

var operation = TableOperation.InsertOrReplace(entity);

await this.CloudTable.ExecuteAsync(operation).ConfigureAwait(false); -> // Throws error

where entity is of type TableEntity

I have referenced following assemblies:

<package id="Microsoft.Azure.KeyVault.Core" version="1.0.0" targetFramework="net451" />
<package id="Microsoft.Data.Edm" version="5.6.4" targetFramework="net451" />
<package id="Microsoft.Data.OData" version="5.6.4" targetFramework="net451" />
<package id="Microsoft.Data.Services.Client" version="5.6.4" targetFramework="net451" />
<package id="Newtonsoft.Json" version="6.0.8" targetFramework="net45" />
<package id="System.Spatial" version="5.6.4" targetFramework="net451" />
<package id="WindowsAzure.Storage" version="6.0.0" targetFramework="net451" />

Note: The code execute fine when run on my local machine, but throws above exception when run on a different environment which we don't own. (Different set of machines hosted somewhere else, and also we don't have access to these machines)

Answer 1

This exception indicates that there is a version mismatch of reference assembly "Microsoft.WindowsAzure.Storage.dll" between the assembly that defines your TableEntity type and the assembly that is operating on it.

Which version of "Microsoft.WindowsAzure.Storage.dll" is referenced by the assembly where your TableEntity type is defined?
