    Features that don't work in Medium Trust?

    I've had success getting Umbraco 4.7.2 and 4.8beta up and running in Medium Trust using both SQL Server and MySQL. However, I did run across a couple things that didn't seem to work, and I'm wondering what else may be lurking for me down the road.

    1. Cannot log in with the AIR Media Uploader application.
    2. Cannot embed Macros via Editor (exception below).
    [SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]
   System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) +0
   System.Security.CodeAccessPermission.Demand() +54
   System.Net.ServicePointManager.set_ServerCertificateValidationCallback(RemoteCertificateValidationCallback value) +67
   umbraco.macro.MacroContentByHttp(Int32 PageID, Guid PageVersion, Hashtable attributes) +1112
   umbraco.presentation.tinymce3.insertMacro.renderMacro_Click(Object sender, EventArgs e) +1294
   System.EventHandler.Invoke(Object sender, EventArgs e) +0
   System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) +154
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +11439394
   System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +11438910
   System.Web.UI.Page.ProcessRequest() +269
   System.Web.UI.Page.ProcessRequest(HttpContext context) +167
   ASP.umbraco_plugins_tinymce3_insertmacro_aspx.ProcessRequest(HttpContext context) +9
   System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +625
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +270

    Anyone else aware of other things I should be worried about?

    There are some packages which also don't work with medium trust. Don't know which ones though. It is a good idea to start a wiki or something where you can see what doesn't work with med trust.

    Hmm, don't think a wiki is the right place to document what packages does not work, since that section is going to disappear from our in near future and all the documentation (which is still relevant) will be a findable in the documentation section.

    But I don't know if this section would be the right place to document, which packages works on medium trust. Perhaps that should be a checkmark option when package creators upload their packages to our, so it clearly states if medium trust i supported or not? (Must admit that I can't remember if this option already exists, since I have unfortunately not been creating a package yet).

    Just my 2 cents (sorry for going a bit off topic in regards to the original question - but I find the discussion about making it more clear what packages supports medium trust relevant).

    Hi Sam,

    While best efforts are made to make Umbraco work in Medium Trust - for the most parts it does - we accept there are some parts which just don't work.

    In order to pin these areas down, would you be so kind as to raise an issue on the CodePlex tracker?

    http://umbraco.codeplex.com/WorkItem/Create

    This will help the team to identify the areas we need to focus on.

    Thanks, Lee.

    PS. I found a biggie last week trying to install Umbraco with MySQL in Medium Trust (default settings) - turned out that Medium Trust doesn't support SocketPermission (which MySql.Data.dll uses) ... so most shared web-hosting enable that option (e.g. a "custom Medium Trust") *fun times* :-)
