If you require Visual Studio 2010 for legacy code maintenance, consider the following safer alternatives:
Visual Studio 2010 Ultimate was released by Microsoft in April 2010. It is a heavy, complex piece of software designed to integrate deeply with the Windows Registry and the .NET Framework (specifically version 4.0).
What makes a version "Portable"? Legitimate software usually requires installation, writing registry keys, installing dependencies (C++ runtimes), and placing files in system directories. A "portable" version is created by reverse-engineering this process: portable visual studio 2010 ultimate
Why VS 2010 is difficult to port: Unlike simple text editors, VS 2010 relies heavily on system-wide COM components and specific versions of the .NET Framework. Creating a truly stable portable version of this specific software is technically challenging and often results in a "frankenstein" build that is prone to crashing.
The "PortableApps.com" platform allows for portable development, but not with full Visual Studio. Instead, users combine several tools to replicate the functionality. If you require Visual Studio 2010 for legacy
You can create a USB drive containing:
Then, write batch scripts that set temporary environment variables (PATH, VSINSTALLDIR, VisualStudioVersion) before invoking msbuild.exe from the command line. Why VS 2010 is difficult to port: Unlike
Important: This allows you to compile C#/.NET projects from a USB drive, but you will not have the Visual Studio IDE (the GUI, IntelliSense, form designers, or debugger). This is for building, not developing.
