U4-6315 - Umbraco 7.2.2 Broke Contour (EDIT: And Dialogue)

Created by Nicholas Westby 23 Feb 2015, 17:05:20 Updated by Shannon Deminick 26 Jun 2017, 07:11:21

I was working on a site that was Umbraco 7.1.8 and was using Contour 3.0.23. When I upgraded to Umbraco 7.2.2, I got this error on Contour forms: !contour-error.png!

When I configured macros to throw exceptions rather than render the error message, this was the exception message:

{"c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\vs\4bba56dc\b9896d6e\App_Web_mvcrendercontourform.cshtml.70df5e80.b7ytxhwl.0.cs(24): error CS0234: The type or namespace name 'Helpers' does not exist in the namespace 'Microsoft.Web' (are you missing an assembly reference?)"}

It seems this is because Umbraco 7.2.2 removes Microsoft.Web.Helpers.dll. I was able to fix this by installing the NuGet package Microsoft.Web.Helpers: !nuget.png!

Not sure what the typical protocol is for removing items with Umbraco upgrades, but thought I'd at least report this in case others come across this issues.

Had another issue with this.

After update from 7.1.4 to 7.2.2 and using @Umbraco.RenderMacro("umbracoContour.RazorRenderForm", new ) my receive 500 error on prod and "<Macro: (,)> " on local

FYI, Mike, I had that same <Macro: (,)> issue on a fresh install of Umbraco 7.2.2. I think the problem is that the macro alias no longer has a dot (i.e., it's now "umbracoContourRazorRenderForm" rather than "umbracoContour.RazorRenderForm"). I ran into a few other problems I needed to solve before the form would work, but I think this was the major one.

Looks like it also broke Dialog (due to the same missing DLL): https://our.umbraco.org/projects/collaboration/dialogue/general/61646-Not-working-in-Umbraco-722!

I can't seem to find Microsoft.Web.Helpers.dll on NuGet anymore. For anybody who needs it, you can find it in the bin folder of the Umbraco 7.2.1 download: https://our.umbraco.org/contribute/releases/721/
