I have problem with Google Analytics API .NET. While connecting to GA via api at line

        var certificate = new X509Certificate2(pathToPrivateKey, passToPrivateKey, X509KeyStorageFlags.Exportable);
        ServiceAccountCredential credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(serviceAccountEmailAddress)
        {
            Scopes = scopes
        }.FromCertificate(certificate));

I tried the same code on Windows 7 and it works.
I have no idea what goes wrong.
Any idea?

check that there aren't extra dlls floating around in GAC or set the reference dlls to copy local. — Linda Lawton - DaImTo, Dec 19 '14 at 07:47
all external dlls - copy local: true, i think that problem could be that in C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0 i had no System.Net.Http.dll so I added it using command gacuitl /i System.Net.Http.dll. This dll is used by HttpClientFactory.cs. — Paweł, Dec 19 '14 at 08:10
@DalmTo I checked on second machine Windows Server 2003 R2 and this time at runtime VS ask me for : c:\code\google.com\google-api-dotnet-client\default\Tools\Google.Apis.Release\bin\Debug\test\default\Src\GoogleApis.Core\Apis\Http\HttpClientFactory.cs — Paweł, Dec 19 '14 at 14:04

It looks like your main problem is the inner exception you got:

InnerException: System.IO.FileLoadException
 Message=Could not load file or assembly 'System, Version=2.0.5.0, Culture=neutral,
 PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes' or one of its dependencies.

The good news is that you should just install the following patch: KB2468871, as suggested here: Could not load file or assembly System, Version=2.0.5.0 in .NET 4 MVC 4 application
