Check if both projects are referencing System.Core. Probably only the first one has it. You've to add it on both to be able to use AesCryptoServiceProvider.

Moreover, as you can see here AesCryptoServiceProvider is only available since .NET 3.5. Check your project's properties, in particular the Target Framework.

var is a reserved keyword. Use a different identifier name or @var.

System.Security.Cryptography.AesCryptoServiceProvider @var;

This may not be the problem - you need to ensure that each project has a reference to System.Core the assembly containing System.Security.Cryptography.

You will also need to ensure that you are targeting a framework version that contains this class (.NET 3.5 and above) - this can be done in the project property pages.

You can't name a variable var because it's a reserved word, use a different name, this will not cause an error :

System.Security.Cryptography.AesCryptoServiceProvider _var;

Edit :

AesCryptoServiceProvider is only supported in .Net framework 4 and 3.5 SP1, change the target framework and it will work and be sure to have System.Security.Cryptography; in that file.

Are the references the same between both project? Just open references and see. I bet you are missing one. However, you really should use a different variable name than var. Also, can you post the exact error?
