Microsoft Visual C++ compiler versioning

The Microsoft Visual C++ compiler version consists of four fields:

M - major version (two digits)
N - minor version (two digits)
B - build version (five digits)
R - revision version

Microsoft-specific compiler macros encode these fields as follows:

_MSC_VER = MMNN
_MSC_FULL_VER = MMNNBBBBB
_MSC_BUILD = R

For example, the compiler version for Visual Studio 2022 version 17.9.0 is 19.39.33519:

  • The major version is 19
  • The minor version is 39
  • The build version is 33519
  • The revision version is 0

The macros reflect these values like this:

  • _MSC_VER = 1939
  • _MSC_FULL_VER = 193933519
  • _MSC_BUILD (the revision) is 0.

Note

Visual Studio 2019 16.8 and 16.9 share the same major and minor versions, and so have the same value for _MSC_VER. As do Visual Studio 2019 16.10 and 16.11. To distinguish them, use _MSC_FULL_VER as described in Service releases starting with Visual Studio 2017.

A brief history of Visual C++ compiler versioning

Visual Studio 6.0 through Visual Studio 2015 (14.0)

  • For major releases, _MSC_VER increases by 100. _MSC_FULL_VER increases by 10,000,000.

  • For minor releases, _MSC_VER increases by 10. _MSC_FULL_VER increases by 1,000,000.

    Note

    Visual Studio .NET 2003 was considered a minor release.

Visual Studio 2017 and later

  • For major releases, the minor version increases by 10.
  • For minor releases, the minor version increases by 1 starting with Visual Studio 2017 version 15.3.

Service releases starting with Visual Studio 2017

Servicing releases can be distinguished by _MSC_FULL_VER. The build field (the BBBBB in the MMNNBBBBB version number) typically increases by 1.

For example, two cases where _MSC_FULL_VER is useful is to distinguish Visual Studio 2019 16.8 from 16.9, and Visual Studio 2019 16.10 from 16.11. That's because those versions share the same major and minor versions, and so have the same value for _MSC_VER.

To distinguish these versions, use _MSC_FULL_VER.
The minimum value of _MSC_FULL_VER for Visual Studio 2019 16.8 is 192829333.
The minimum value of _MSC_FULL_VER for Visual Studio 2019 16.9 is 192829910.

Version macros

Recall that the version number consists of four fields:

M - major version (two digits)
N - minor version (two digits)
B - build version (five digits)
R - revision version

_MSC_VER distinguishes between major and minor releases. It has the form: MMNN.

_MSC_FULL_VER represents the major, minor, and build version of the compiler. It has the form: MMNNBBBBB. Use it to distinguish between different versions of the compiler, including servicing releases. See Service releases starting with Visual Studio 2017 for more information about Visual Studio 2019 16.8, 16.9, 16.10 and 16.11.

_MSC_BUILD represents the build version of the compiler. It has the form: R. Use it to distinguish between servicing releases.

When the major version changed between Visual Studio 2013 and Visual Studio 2015, _MSC_VER reflected the change by going from 1800 to 1900.

An example of a minor change is from Visual Studio 2022 17.1 to Visual Studio 2022 17.2. In that case, _MSC_VER changed from 1931 to 1932.

The following table lists the Visual C++ compiler _MSC_VER for each Visual Studio release:

Visual Studio version _MSC_VER
Visual Studio 6.0 1200
Visual Studio .NET 2002 (7.0) 1300
Visual Studio .NET 2003 (7.1) 1310
Visual Studio 2005 (8.0) 1400
Visual Studio 2008 (9.0) 1500
Visual Studio 2010 (10.0) 1600
Visual Studio 2012 (11.0) 1700
Visual Studio 2013 (12.0) 1800
Visual Studio 2015 (14.0) 1900
Visual Studio 2017 RTW (15.0) 1910
Visual Studio 2017 version 15.3 1911
Visual Studio 2017 version 15.5 1912
Visual Studio 2017 version 15.6 1913
Visual Studio 2017 version 15.7 1914
Visual Studio 2017 version 15.8 1915
Visual Studio 2017 version 15.9 1916
Visual Studio 2019 RTW 16.0 1920

Visual Studio 2019 version 16.2 1922
Visual Studio 2019 version 16.3 1923
Visual Studio 2019 version 16.4 1924
Visual Studio 2019 version 16.5 1925
Visual Studio 2019 version 16.6 1926
Visual Studio 2019 version 16.7 1927
Visual Studio 2019 version 16.8, 16.9 a 1928
Visual Studio 2019 version 16.10, 16.11 b 1929
Visual Studio 2022 RTW 17.0 1930
Visual Studio 2022 version 17.1 1931
Visual Studio 2022 version 17.2 1932
Visual Studio 2022 version 17.3 1933
Visual Studio 2022 version 17.4 1934
Visual Studio 2022 version 17.5 1935

Visual Studio 2022 version 17.8 1938
Visual Studio 2022 version 17.9 1939
Visual Studio 2022 version 17.10 1940

a Visual Studio 2019 16.8 and 16.9 share the same major and minor versions (and so have the same value for _MSC_VER). To distinguish them, use _MSC_FULL_VER. The minimum value of _MSC_FULL_VER for Visual Studio 2019 16.8 is 192829333. The minimum value of _MSC_FULL_VER for Visual Studio 2019 16.9 is 192829910.

b Visual Studio 2019 16.10 and 16.11 share the same major and minor versions (and so have the same value for _MSC_VER). To distinguish them, use _MSC_FULL_VER. The minimum value of _MSC_FULL_VER for Visual Studio 2019 16.10 is 192929917. The minimum value of _MSC_FULL_VER for Visual Studio 2019 16.11 is 192930129.
