SharpDevelop Community

Hi, all. I have just installed #Develop on my box. Installation goes fine, and the IDE launches without problems. But when I create a new solution I get the following exception:

--------------- 

 .NET Version        : 2.0.50727.42

Also, the forms designer fails to start (any programming language), showing this error message:

-----------
System.InvalidOperationException: The designer could not be shown for this file because none of the classes within it can be designed.  The designer inspected the following classes in the file:

    MainForm --- The base class 'System.Object' cannot be designed.

   at System.ComponentModel.Design.Serialization.CodeDomDesignerLoader.PerformLoad(IDesignerSerializationManager manager)

Thanks for the help,

See this post for the first issue.
For the second one, does the file you're trying to design contain a class that inherits from System.Windows.Forms.Form or System.Windows.Forms.UserControl?

About the xml exception, I couldn't find the source of the error. In the mentioned thread it is suggested that a xml file in the .NET installation could be corrupt. Using cygwin I checked that all xml files have no 'invalid 0x14' character:

    diego@draco /cygdrive/c/WINDOWS/Microsoft.NET/Framework/v2.0.50727
    $ for f in *xml; do od -t x $f | grep '\<14\>'; done

Did the same with all xml files in the #Develop installation. 

Regarding the forms designer, it fails to start immediately after creating a new project, thus the class derives from System.Windows.Forms.Form.

Thanks,

Diego
