Conditional Compilation Directives in aspx file?

[Praveen Ramesh]

Hi,

Is there some kind of support for "Conditional Compilation Directives" in
the aspx file?

I want to enclose the Register tag as follows:
#if DOTNET10
<%@ Register TagPrefix="sfwg" Namespace="CustomNameSpace"
Assembly="CustomAssembly1.0"%>
#else
<%@ Register TagPrefix="sfwg" Namespace="CustomNameSpace"
Assembly="CustomAssembly1.1"%>
#endif

And of course be able to define the "DOTNET10" directive somewhere (maybe in
the web.config file).

TIA,
Praveen

You should use assembly redirects as this is a built in way to get the version
you want via configuration. In essence this lets you configure in the config
file which version to use. Here's a link to the docs:

Thanks for Brock's inputs.

Hi Praveen,

So far there hasn't any conditional compilation directives in asp.net's
aspx page. And as for assembly's version redirect, .net has the formal
means through the assembly redirecting /binding configuration. And the
version redirection is actually a runtime behavior which occur at the
loading time of a certain assembly. Also, that assembly must be
strong-named so as to take advantage of the version redirections. Here are
some further resource on .net's assembly version redirection:

Hope also helps. Thanks,
