I have a dotnetnuke based web application and a separate web service api. Both the project consume 2 common dlls.

here is the description of dlls:

-MyCommon.dll (contains common code used by different modules, it also has dataprovider class)
-MyCommon.SqlDataProvider.dll (uses dataprovider class of myCommon.dll)

Now, my DNN based web application is able to consume the dll properly.

[b]However, with my separate web service code I get the following error.[/b]

[i]DotNetNuke.Services.Exceptions.PageLoadException: The type initializer for 'xx.xxx.DataProvider' threw an exception. ---> System.TypeInitializationException: The type initializer for 'xx.xxx.DataProvider' threw an exception. ---> System.ArgumentNullException: Value cannot be null. Parameter name: type at System.Activator.CreateInstance(Type type, Boolean nonPublic) at System.Activator.CreateInstance(Type type) at DotNetNuke.Framework.Reflection.CreateObject(String TypeName, String CacheKey, Boolean UseCache) at DotNetNuke.Framework.Reflection.CreateObject(String ObjectProviderType, String ObjectProviderName, String ObjectNamespace, String ObjectAssemblyName, Boolean UseCache) at DotNetNuke.Framework.Reflection.CreateObject(String ObjectProviderType, String ObjectNamespace, String ObjectAssemblyName) at xx.xxx.DataProvider.CreateProvider() in E:\DNN\xxx\xxx\xxx\DataProvider.cs:line 56 at xx.xxx.DataProvider..cctor() in E:\DNN\xxx\xxx\xxx\DataProvider.cs:line 50 [/i]

here is how dataprovider CreateProvider call looks like:

[code]private static void CreateProvider()
{
objProvider = (DataProvider)Reflection.CreateObject("data", "MyDll.Common", "");
}[/code]

Also have tried putting Assembly name in CreateObject call, but that failed both the applications.

Any help would be highly appreciated.

Thanks in advance.
