OWIN Alter UseStatic?

Question

The “UseStatic” OWIN AppBuilder bits provide files from the local file system, which are convenient for some situations, but I would like it to deliver content from the IDictionary in memory, which I previously filled when the application started. Can someone point me in a good direction to explore redefinition / change of behavior?

Thanks.

You will want to implement your own classes IFileSystemand IFileInfo. An example of this can be seen in the dev branch on CodePlex in the section src/Microsoft.Owin.FileSystems/EmbeddedResourceFileSystem.cs. It was a community contribution based on this project .

After implementation, you will use it like this

public class InMemoryFileSystem : IFileSystem
{
    public InMemoryFileSystem(IDictionary<string, object> files)
    {}
}

var files = LoadFilesIntoDictionary();

app.UseStaticFiles(options => {
    options.WithFileSystem(new InMemoryFileSystem(files));
});
