Castle Windsor upgrade causes TypeLoadException for generic types
- by Neil Barnwell
I have the following mapping in my Castle Windsor xml file which has worked okay (unchanged) for some time:
<component id="defaultBasicRepository"
service="MyApp.Models.Repositories.IBasicRepository`1, MyApp.Models"
type="MyApp.Models.Repositories.Linq.BasicRepository`1, MyApp.Models"
lifestyle="perWebRequest"/>
I got this from the Windsor documentation at http://www.castleproject.org/container/documentation/v1rc3/usersguide/genericssupport.html.
Since I upgraded Windsor, I now get the following exception at runtime:
Description: An unhandled exception
occurred during the execution of the
current web request. Please review the
stack trace for more information about
the error and where it originated in
the code.
Exception Details:
System.TypeLoadException:
GenericArguments[0], 'T', on 'MyApp.Models.Repositories.Linq.BasicRepository`1[TEntity]'
violates the constraint of type parameter 'TEntity'.
Source Error:

I'm using ASP.NET MVC 1.0, Visual Studio 2008 and Castle Windsor as downloaded from http://sourceforge.net/projects/castleproject/files/InversionOfControl/2.1/Castle-Windsor-2.1.1.zip/download
Can anyone shed any light on this? I'm sure the upgrade of Castle Windsor is what caused it - it's been working well for ages.
