Remarks
An assembly can be associated with only one unmanaged resource. This means that calling DefineVersionInfoResource or DefineUnmanagedResource after either one of the methods was called previously will throw the System.ArgumentException. Multiple unmanaged resources need to be merged with a tool such as the Microsoft ResMerge utility (not supplied with the common language runtime SDK).
Empty argument strings get written as a single space. Spaces are substituted for null characters in the argument strings.
The information is inferred from the AssemblyName object used to define this dynamic assembly. This assembly's custom attributes override information specified in the AssemblyName object.
Note
Starting with the .NET Framework 2.0 Service Pack 1, this member no longer requires ReflectionPermission with the ReflectionPermissionFlag.ReflectionEmit flag. (See Security Issues in Reflection Emit.) To use this functionality, your application should target the .NET Framework 3.5 or later.

DefineVersionInfoResource(String, String, String, String, String)
Defines an unmanaged version information resource for this assembly with the given specifications.

The name of the product with which this assembly is distributed.
- productVersion
- String
The version of the product with which this assembly is distributed.
- company
- String
The name of the company that produced this assembly.
- copyright
- String
Describes all copyright notices, trademarks, and registered trademarks that apply to this assembly. This should include the full text of all notices, legal symbols, copyright dates, trademark numbers, and so on. In English, this string should be in the format "Copyright Microsoft Corp. 1990-2001".
- trademark
- String
Describes all trademarks and registered trademarks that apply to this assembly. This should include the full text of all notices, legal symbols, trademark numbers, and so on. In English, this string should be in the format "Windows is a trademark of Microsoft Corporation".
Exceptions

Remarks

Multiple unmanaged resources need to be merged with a tool such as the Microsoft ResMerge utility (not supplied with the common language runtime SDK).
Empty argument strings get written as a single space. Spaces are substituted for null characters in the argument strings.
The structure of the version resource includes data that identifies the version, language, and distribution of the file. Installation programs use the functions in the file installation library (VER.DLL) to retrieve the version information resource from a file and to extract the version information blocks from the resource.
