Represents the version number of an assembly. [Edit]

[System.Runtime.InteropServices.ComVisible(true)] public sealed class Version : ICloneable, IComparable, IComparable<Version>, IEquatable<Version>

Thread Safety

All public static members of this type are safe for multithreaded operations. No instance members are guaranteed to be thread safe.

Remarks

Version numbers for an assembly consist of two to four components: major, minor, build, and revision. Components major and minor must be defined. Build and revision components are optional. Component revision can be used if and only if build is defined. All defined components must be a int greater than or equal to zero.

Note:

By convention, the components are used as follows:

• Major: Assemblies with the same name but different major versions are not interchangeable. This would be appropriate, for example, for a major rewrite of a product where backwards compatibility cannot be assumed.
• Minor: If the name and major number on two assemblies are the same, but the minor number is different, this indicates significant enhancement with the intention of backwards compatibility. This would be appropriate, for example, on a "point release" of a product or a fully backward compatible new version of a product.
• Assemblies with the same name, major, and minor version numbers but different revisions are intended to be fully interchangeable. This would be appropriate, for example, to fix a security hole in a previously released assembly.
• A difference in build number is intended to represent a recompilation of the same source. This would be appropriate, for example, because of processor, platform, or compiler changes.
