OpenSSL C#.NET Wrapper Error while DLL generation

I am on windows and I am using Microsoft Visual C# 2010 Express Edition. I downloaded the OpenSSL .NET Wrapper "openssl-net-0.4.4-src" and I tryed to compile it. I found two solutions : one for Visual 2005 and one for 2008. I chose the 2008 one, after converting it to 2010 environment. While converting, some components where not converted. And while compiling I got errors like some namespaces were not found. I found that the solution is using "using NUnit.Framework;" and i does not exist.

Questions

Is "NUnit.Framework" the problem ? if yes, should I download it and put a reference on it? Or should I use 开发者_开发百科directly Microsoft Visual C# 2008 to avoid the conversion? Thanks for any help.

Yes, if it can't find NUnit.Framework, you should download it. Using Visual Studio 2008 won't help with this - if you're missing an assembly, you're missing an assembly...
