| 27 | <p>Every managed custom action package should contain a CustomAction.config file, even though it is not required by the toolset. |
| 28 | Here is a sample:</p><pre><font face="Consolas, Courier New"> |
| 29 | <?xml version="1.0" encoding="utf-8" ?> |
| 30 | <configuration> |
| 31 | <startup> |
| 32 | <supportedRuntime version="v2.0.50727"/> |
| 33 | </startup> |
| 34 | </configuration></font></pre><br /> |
| 35 | <p>The configuration file follows the standard schema for .NET Framework |
| 36 | configuration files <a target=_blank href="http://msdn2.microsoft.com/en-us/library/9w519wzk(VS.80).aspx">documented on MSDN</a>.</p> |
| 37 | <p><br/></p> |
| 38 | <p><b>Supported Runtime Version</b></p> |
| 39 | <p>In the startup section, use <a target=_blank href="http://msdn2.microsoft.com/en-us/library/w4atty68(VS.80).aspx">supportedRuntime</a> |
| 40 | tags to explicitly specify the version(s) of the .NET Framework that the custom action should run on. |
| 41 | If no versions are specified, the chosen version of the .NET Framework will be |
| 42 | the "best" match to what WixToolset.Dtf.WindowsInstaller.dll was built against.</p> |
| 43 | <p><font color="red"><b>Warning: leaving the version unspecified is dangerous</b></font> |
| 44 | as it introduces a risk of compatibility problems with future versions of the .NET Framework. |
| 45 | It is highly recommended that you specify only the version(s) |
| 46 | of the .NET Framework that you have tested against.</p> |
| 47 | <p><br/></p> |
| 48 | |
| 49 | <p><b>Other Configuration</b></p> |
| 50 | <p>Various other kinds of configuration settings may also be added to this file, as it is a standard |
| 51 | <a target=_blank href="http://msdn2.microsoft.com/en-us/library/kza1yk3a(VS.80).aspx">.NET Framework application config file</a> |
| 52 | for the custom action.</p> |
