• Visual Studio project template for creating Units of Measurement C# class library.
• Units of measurement are generated from simple definitions in a text file (data model) by means of (design-time) T4 text template. See here for an overview of unit generation process.
• Units of measurement are generated as types (partial structs). Thus dimensional analysis can be performed as a syntax check at compile time. Dimensional issues are displayed in Visual Studio as syntax errors. See this example.
• All fundamental dimensions are supported i.e.: Length, Time, Mass, Temperature, ElectricCurrent, AmountOfSubstance, LuminousIntensity as well as Other (e.g. Money for currency units) and any of their combinations.
• Arithmetic (+, ++, -, --, *, /) and comparison (==, !=, <, <=, >, >=) operators to perform calculations directly on quantities of unit type. See this example.
• Conversions of quantities to/from other (but compatible) unit types.

Assuming you have already installed UnitsOfMeasurement.VSIX component (see Releases page for download and installation instructions), follow this general process to create a library:

1. Create a new project of type "Units of Measurement C# Class Library".
2. Go to Units folder in Solution Explorer:
3. edit _definitions.txt to specify units of measurement that you need for your solution.
4. (optional) modify ProcessUnit and/or ProcessScale method(s) in _generator.tt to customize template text for generating units and/or scales.
5. right-click on _generator.tt, select "Run Custom Tool" command (press OK on Security Warning).
6. (optional) create extension (.cs) files to extend generated unit/scale (partial) structs with additional properties, methods or operators,
7. Go to RuntimeLoader folder (not available in release 1.0):
8. (optional) modify ProcessUnit and/or ProcessScale method(s) in Generator.tt to customize template text for generating run-time (late) units and/or scales.
9. right-click on Generator.tt, select "Run Custom Tool" command (press OK on Security Warning).
10. Compile the project.
