NAG Library for .NET Version 2: Changes in release 2b

Introduction

Release 2b (Assembly version 2.1.0.5) is an update to Release 2 (Assembly version 2.0.1.6). It has the same product code and default installation location, however the different assembly version strings allow both versions to be installed side-by-side and registered separately in the Global Assembly Cache if that is required.

The main feature of this release is a new version of the assembly NagLibrary.dll that is compiled for the AnyCPU target and will dynamically reference the underlying 32- or 64-bit native code library depending on the .NET runtime in use. The existing NagLibrary32.dll and NagLibrary64.dll are still provided, as before, although compiled with a newer version of Visual Studio (2013), referencing the .NET runtime 4.0.

New Files

NagLibrary.dll

NagLibrary.xml

Version of the NagLibrary (and its intellisense support for Visual Studio) compiled for the AnyCPU target and usable in both 32- and 64-bit .NET environments.
If this version is used, the library identification method, A00.a00aa, will report a version of
NAG Library for .NET Release 2 Any CPU (x86)
or
NAG Library for .NET Release 2 Any CPU (x64)
depending on the .NET runtime being used.

Changes

In addition to the new files listed above, the following changes have been made:

• Visual Studio 2013 was used, with a dependency on Framework 4.0 selected. (The first release used Visual Studio 2010 and referenced its default framework, 4.0.)
• The handling of the array H in e04nf was corrected to not enforce a large array size in the case a user suppled qphess method is used.
• The example file for f08nb was corrected. (It was printing the real part twice rather than the real and imaginary parts separately.)
• The example Windows application that demonstrates the example programs now references NagLibrary.dll rather than NagLibrary32.dll and will run in 64-bit mode by default on x64 platforms.
• The Installer now adds the assembly version string to the registry at install time (required by some code validation tools).
