Can't order packages by name

[Guest]

VisualStudio 2012, NuGet plugin v. 2.6.40627.9000.

• Right click on a project, "Manage NuGet Packages"
• Select Online (ProGet repository)
• Select "Name: Descending" from the combo box "Sort by"

Expected: list of available packages, sorted by name
Actual: error "Could not connect to the feed specified"

Inspecting the HTTP traffic with Fiddler, this is the request issued to ProGet:

GET https://<progetServerAddress>/nuget/default/Search()?$filter=IsAbsoluteLatestVersion&$orderby=concat(Title,Id),Id&$skip=0&$top=30&searchTerm=''&targetFramework='net40'&includePrerelease=true HTTP/1.1

One or more errors occurred.

Thanks for the report; it would appear that NuGet 2.6 added a concat(Title,Id) function to their orderby query. A bit bizarre (considering it then orders by Id), but then again, it's NuGet...

We'll logged this as PG-119 and will fix this in ProGet 2.1.3.

I've installed v 2.1.3 but the issue seems not solved.
Did you have a target release date for this fix?

Thanks

Unfortunately that issue PG-119 was moved to a future a release because of the priority of the other issues listed in the release notes: http://inedo.com/proget/release-notes#2.1.3

We will try to get this in 2.1.4.
