Setting up API for iPhone-app, getblogs throws error

Hi.

I'm trying to set up a site in order to manage it with the new iPhone-app. I have followed the steps to the letter and all the calls are functioning except the getblogs-call.

When trying to call /api/custom/getblogs?username=administrator&password=[removed] the following exception is thrown:

[MissingMethodException: Method not found: 'System.Collections.Generic.IList`1<System.String> Mindroute.Core.Search.ContentQuery.get_ContentTypes()'.]

The site is running Lemoon 4.3.2.0.

Is this an upgraded lemoon 4.2.x site or a new lemoon 4.3.2 site? There seems to be an issue with the:

--------------------
ContentQuery query = new ContentQuery();

query.ContentTypes.Add(typeof(Blog).FullName); //This is where the error seems to occur...
---------------

Could you please try to add this code to a standard template or control on the web site and see if it throws an error? Try the code:

---------------------

ContentQuery query = new ContentQuery();

query.ContentTypes.Add(typeof(Blog).FullName);

query.OrderBy.Add(new SortItem(ContentColumn.Title, SortDirection.Ascending));

//query.PageSize = 10;

PagedList<Mindroute.Core.Model.Content> result = contentservice.Search(query);

----------------

I think you are still using the 4.2.x assemblies since there was a change in the ContentQuery.ContentTypes.Add() method in 4.3.

Thank you Magnus!

You were absolutely right! I doubled checked the actual assemblies used in the application and they were indeed 4.2.x, replacing them solved the problem. Thanks for your swift reply!

After fixing the problem I sought to find the underlying problem to why the "wrong" assemblies were being used in the first place. After some digging I found it:

In 4.2.x the Visual Studio templates were located at ...\Documents\Visual Studio 2010\Templates\ProjectTemplates\Visual C#\lemoon421-vstemplate.zip

In 4.3.x i looks like this has changed to instead be located at ...\Documents\Visual Studio 2010\Templates\ProjectTemplates\Visual C#\Web\lemoon-vstemplate.zip

The major difference here is when I choose to create a new project in VS. With 4.2.x I found the "Lemoon Web Application"-project directly under the filter "Visual C#". After installing the 4.3.x-templates (in a new location) the project is found under "Visual C#->Web"-filter. As such the templates wasn't overwritten as in earlier versions.

Unaware of this change I chose the old version template.

I have now removed them to avoid future confusion.

Thanks again!
