I got the following exception when my WebRole tries to start:

{"Could not load file or assembly 'Microsoft.WindowsAzure.Diagnostics, Version=2.0.0.0, 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)":"Microsoft.WindowsAzure.Diagnostics, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"}

I use Visual Studio 2012 with Azure SDK 2.1

Try find in your .csproj file the following: 

<Reference Include="Microsoft.WindowsAzure.Diagnostics, Version=2.0.0.0 />

and replace it with

<Reference Include="Microsoft.WindowsAzure.Diagnostics, Version=2.1.0.0 />
