Who can help me?

Dario Crivelli

The Server, in this case, just complains for an unexpected interruption of the connection toward the Remote Adapter.
Please check what happens in the latter process; does it crash?
Are you using the VB or C# version of the Remote Adapter?

I use dotnet 4.0 to build Remote Adapter, is it something wrong?

thitkhohotvit

I found the problem, lightstreamer not support dotnet 4.0, thanks admin.

Hi,

from my experience I can tell you that the dlls are compatible with .NET framework 4.0
Why do you say that's not?
Do you get any compile errors while building your remote adapter?

i am getting compline time error, i have created sample application using .NET3.5 its working fine, when i tried to run the same using .NET4.0 it throwing errors.
added the "DotNetAdapter_N2" ref file

The type or namespace name 'Lightstreamer' could not be found (are you 
missing a using directive or an assembly reference?)

The referenced assembly "DotNetAdapter_N2" could not be resolved because 
it has a dependency on "System.Web, Version=4.0.0.0, Culture=neutral, 
PublicKeyToken=b03f5f7f11d50a3a" which is not in the currently targeted framework 
".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies
 not in the targeted framework or consider retargeting your project.

Hi,

I finally was able to reproduce the issue using ".NET Framewrk 4 Client Profile" which is different from ".NET Framework 4" (see http://goo.gl/bcCz )

please can you double check that you're using ".NET Framework 4"?

msgiribabu

I am using .NET Framework 4 Client Profile, let me know any alternative to run the application, i how to create a POC using VS.NET 2010, and i am searching for database related samples. i need to retrieve data from DB, there is no samples in help file. let me know asap

Mone

as said, to let your application work you have to use the complete .NET Framework instead of using the client profile. Just changing that in your project properties should solve the issue.

About the db there is not an official example, btw some discussions about it are available on the forum. Check out the following threads:
