P4.NET is a fork of the original P4.NET component created by Shawn Hladky. It provides managed implementation of Perforce API. Main features of this fork (as opposed to Shawn's original):

• Support for CLR 2 (.NET 2.0, 3.0, 3.5)
• Support for CLR 4 (.NET 4.0)
• Single AnyCPU assembly (works in both 32 and 64 bit .NET runtimes)

Based on: http://public.perforce.com:8080/guest/shawn_hladky/P4.Net/main/

Current version: 2.0.0.3 (Feb 15, 2011; sources; binaries)

Build requirements: Visual C++ 2010 (free edition should have no problems)

1. Download sources from GitHub or clone the repository using Git

2. Run/double-click (project_root)/p4.net_build.cmd. This will produce the following binaries:

• bin/Debug_v2.0/P4API.dll (pdb, xml) - signed P4.NET assembly in debug mode, compiled for .NET 2.0 (i.e. usable from .NET 2.0, 3.0 and 3.5)
• bin/Release_v2.0/P4API.dll (pdb, xml) - signed P4.NET assembly in release mode, compiled for .NET 2.0 (i.e. usable from .NET 2.0, 3.0 and 3.5)
• bin/Debug_v4.0/P4API.dll (pdb, xml) - signed P4.NET assembly in debug mode, compiled for .NET 4.0
• bin/Release_v4.0/P4API.dll (pdb, xml) - signed P4.NET assembly in release mode, compiled for .NET 4.0

Note: It is not possible to compile the C++ component of P4.NET (mixed-mode assembly p4dn, embedded in assembly p4api) with statically linked runtime libraries. This means that p4dn.dll is dependent on msvcrt100.dll (or msvcrt100d.dll in debug build). Because different versions of runtime DLLs are needed for different process bitness, it is not possible to distribute a single copy of the runtime DLLs with P4.NET (when running on a 64 bit operating system, a .NET process can run in 32 bit mode where a 32 bit p4dn will be loaded that will require 32 bit msvcrt100.dll, while another .NET process can run in 64 bit mode where a 64 bit p4dn will be loaded that will require 64 bit msvcrt100.dll).

Installing Visual C++ 2010 runtime is the easiest way to solve this problem (if another program already installed the runtime, no action is needed) :

• Download runtime installer for 32-bit (x86) Windows

• Download runtime installer for 64-bit (x64) Windows
