> XVersion

Represents a four-part version number.

## Syntax

```cpp theme={null}
typedef struct XVersion {  
    union
    {
        struct
        {
            uint16_t major;  
            uint16_t minor;  
            uint16_t build;  
            uint16_t revision;
        };
        uint64_t Value;
    };
} XVersion  
```

## Remarks

Gaming Runtime features use the **XVersion** structure to represent the version information. The [XSystemAnalyticsInfo](https://docs.xbox.com/reference/system/xsystem/structs/xsystemanalyticsinfo.md) and [XSystemRuntimeInfo](https://docs.xbox.com/reference/system/xsystem/structs/xsystemruntimeinfo.md)
structures use **XVersion** to represent versions for operating system and the gaming runtime. In
addition, the [XPackageDetails](https://docs.xbox.com/reference/system/xpackage/structs/xpackagedetails.md) structure uses **XVersion** to represent a
package's version.

## Requirements

**Header:** XGameRuntimeTypes.h

**Supported platforms:** Windows, XBOX One family consoles and XBOX Series consoles
