I'm using Visual Studio 2010 and trying to use the BigInteger type in a C# program. This type is supposed to be available in System.Numerics namespace, but I don't seem to have that installed in the .Net 4.0 framework. When I type "using System.Numerics;" in VS2010, a red underline appears under the "Numerics". Has anyone else ever had this problem?
If so, how do you resolve it? I just re-downloaded and re-installed (repaired) the .Net 4.0 framework, but that didn't help. I've never had any problems with other C# programs that I've written, so I'm wondering what I'm missing.

BitOperations Class (System.Numerics)Provides utility methods for intrinsic bit-twiddling operations. The methods use hardware intrinsics when available on the underlying platform; otherwise, they use optimized software fallbacks.
If you're using VS 2010, you can simply type "system. numerics" on the search up top. Then just select the reference and click Add, then Close.
The BigInteger type is an immutable type that represents an arbitrarily large integer whose value in theory has no upper or lower bounds. The members of the BigInteger type closely parallel those of other integral types (the Byte, Int16, Int32, Int64, SByte, UInt16, UInt32, and UInt64 types).
Informally, a vector is an array of numeric values. A matrix is conceptually a two-dimensional data structure of numeric values. The demo program begins by creating and displaying a vector with four cells, each initialized to 3.5. Next, the demo creates a 3x4 (3 rows, 4 columns) matrix.
You need to add an assembly reference to System.Numerics.dll
The MSDN entry on BigInteger states:
BigInteger Structure
...
Namespace: System.Numerics
Assembly: System.Numerics (in System.Numerics.dll)
