Question

I am hosting the ASP.Net runtime in my exe but I find that if I try to access htm or xml files from the browser, it gives a 404.

I can access aspx, asmx and other asp.net related files just fine.

Is there any configuration that I need to do to server other file extensions and if so, what?

Answer 1

I think you need:

<modules>
    <add name="DefaultDocumentModule" />
    <add name="DirectoryListingModule" />
    <add name="StaticFileModule" />
    <add name="AnonymousAuthenticationModule" />
</modules>
