Moving from beta 7 to beta 8 in ASP.NET 5 (MVC 6)

So Beta 8 was recently announced, and I thought I'd update DotNetMashups to beta 8.

In case you havn't been paying attention, recently it was announced that helios was no longer a thing. Helios was the loader for ASP.NET 5 in IIS. Instead they are using the http Platform Handler to proxy the connections to kestrel.

So I thought that this was going to be a difficult update. I loaded the announcements repo in my browser and got to work. You can view the Pull request here.

The first thing I did was update my visual studio tools, do a dnvm update, then update my packages to use beta8. I then ran into was 2 build errors in my startup.cs It seemed that app.UseErrorPage(); was renamed to app.UseDeveloperExceptionPage(); which seems like a sensible rename. The second thing was that app.UseErrorHandler("/Home/Error"); became app.UseExceptionHandler("/Home/Error"); again 100% sensible.

I deleted my hosting.ini, I changed my web command from using "web": "Microsoft.AspNet.Hosting --config hosting.ini" to "web": "Microsoft.AspNet.Server.Kestrel" and I set my web.config to look like the following. That was basically it. Overall really simple!

<configuration>
  <system.webServer>
    <handlers>
      <add name="httpPlatformHandler" path="*" verb="*" modules="httpPlatformHandler" resourceType="Unspecified" />
    </handlers>
    <httpPlatform processPath="%DNX_PATH%" arguments="%DNX_ARGS%" stdoutLogEnabled="false" startupTimeLimit="3600" />
  </system.webServer>
</configuration>
