Argument types do not match

Hi Guys,

I am evaulating your product and my manager wanted me to do a end to end testing on our dev server to make sure that its all good. So i started to play with your sample "FirstSilverlightApp" we are connection it to our dbmodel everthing is working fine on local maching and when we deploy it on to the server
We can Connect and Login no errors but when we click on Fetch I am running a simple query to fetch a Site table with below structure.

I have already spend good couple of days to fix this on dev server with iis7 .net 4.0 SQL 2008 64bit win 2008.

No Luck Please help ????????????? Thanks In advance

Thanks for a quick reply but I am not using any constants in query

 private void AddQueries()
        {             
_queries = new Dictionary<string, IEntityQuery>();

            _queries.Add("Get all Sites", _entityManager.Sites);
}

Just using the sample application to return the table

Just to complicate matter further. Our Entity model is in a class lib "POS.SL.BO" and "POS.SL.DomainModel" is a Silverlight lib which has reference to all the generated code from  "POS.SL.BO"

And we reference "POS.SL.DomainModel" from sample silverlight app.

Any help will be appreciated.

Thanks in advance

Mark

Thanks for your quick reply

1. Is POS.SL.BO the assembly/project where the EDMX file was added,

Yes

2. and POS.SL.DomainModel a Silverlight class library project with file links to the generated code?

Yes

3. Is POS.SL.BO a Silverlight or .NET class library?  

.Net class library

4. Which assembly is in your web application's bin folder?

POS.SL.BO.dll

5. Is there any possibility that the DevForce assembly versions in the XAP vs. the web's bin folder are not the same?

We have never used devforce before this is the first time we have installed and testing it.

6. Are all required DevForce and application assemblies in the bin folder?
 
yup

This are in web bin

IdeaBlade.Core
IdeaBlade.EntityModel
IdeaBlade.EntityModel.Edm
IdeaBlade.EntityModel.Server
IdeaBlade.EntityModel.Web
IdeaBlade.EntityModel
IdeaBlade.Linq
IdeaBlade.Validation

7. Do your other queries work?

Nope none of the queries work tried few no luck, login and connect seems to work and debug log is getting generated we can load the EntityService.svc without any errors.


Thanks once again for your help will be great if we can fix this

Hi Guys after spending few hours finally fixed it.

We had some other dlls in web bin which had a conflict with devforce ones.

I created a new asp.net 40 web application on server and it started to work.

then we stared to introduce one dll at a time and found the the one which was causing this error.

Thanks again for your help
