FAQ: How do I retrieve assembly attributes at runtime?

I'm building an application targeted at the .NET Framework 4 and want to use the Logging Application Block and notice that the 5.0.414.0 version installed by the MSI is targeted at the 2.0.50727 runtime.  If this 2.0 version of the Logging Application Block is used, are there any performance problems or other issues which would suggest that I install the Logging Application Block source code and compile it targeted at .NET Framework 4 and use that DLL??

TIA,

George

I am desigining a windows form wherein I allow the user to upload a particular assembly file. The assembly file can be present at any location on the user's hard drive. I want to now load this assembly and read the classes present in this assembly. I am doing this using Reflection, however I am not unable to unload the assembly which is once loaded  through reflection. I have tried using AppDomains, but I am unable to load the assembly through AppDomain. Whenever I try to load my assembly from the appDomain I get a error message "The specified assembly file or one of its dependencies does not exist". I have set the ApplicationBase path of the AppDomain to the location where the assembly file is being uploaded from. However I am still not able to load the assembly from the AppDomain.

Can anyone please let me know in case I am missing something. Any help on this will be highly appreciated.

Thanks,

Hola.

He estado buscando mucho y ya no se que hacer con este error. Tengo reporting services 2008, .net framework 4 y trabajo con report builder 2.

Todos los reportes los puedo publicar correctamente en el report server, pero cuando voy a publicar el que tiene referencia a una dll propia obtengo este error: this assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded (rsErrorLoadingCodeModule).

Ya reinstale el framework 4, la dll ya se encuentra en la carpeta bin de report server y ya esta registrada usando la herramienta gacutil.exe.

Mi propia dll esta hecha bajo .net framework4.

Este montaje lo tengo en un servidor y funciona correctamente, pero el problema se me presenta a subir esto es un servidor propio de un cliente.

Agradezco la colabroración que me puedan prestar.

PD. me disculpan si lo publique en el sitio que no era... pero no supe a que otra categoría asociarlo.

Could not load file or assembly '' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.". Please tell me how can i resolve this issue?

I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.

I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Dim objConn As New SqlConnection("Server=<servername>;uid=<userid>;pwd=<password>;database=master")

The type 'System.Data.Linq.DataContext' is defined in an assembly that is not referenced. You must

        protected void LinqDataSource_ContextCreating(object sender, LinqDataSourceContextEventArgs e)
        {
            e.ObjectInstance = new KaruselaDataContext(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
        }
