Hi Ton

That is because you upgrade from a version of Dynamicweb that runs on .NET 4 and 8.6 is based on 4.5. It is the same runtime, but compiler and framework is different.

This error occurs because your target framework in web.config is set to 4.0 - change it to 4.5 - make a diff on the web.config from DW.

Nicolai,

I changed the section (see below), but no effect. Any suggestions?

Thanks

Did you install 4.5 on the server?

Framework 4.5.1 appears to be installed, still the error occurs. 

Any suggestions?

Hm. Need a copy of the solution or an access to the server then. Or you should really upgrade to 8.6.1.* first. We might have fixed it.

We're discussing the possibilty of giving access to our test environment.

By the way, in my opinion, the release docs should mention it if this problem has been fixed already. We spend too much time updating because it's not always clear if problems have been fixed or not.

 

Thanks,

Ton

Nicolai, in what way do you wish to have access to that environment?

Is web-access enough, or do you need Remote Desktop access?

Hi Ton and Jeroen

I need RDP access if you can not locate the error your selves.

The file Admin/Module/NewsLetterV3/Control/SelectNewsItems.ascx has not been changed since 2011.

​This error probably has something to do with .NET version and/or web.config. If your web.config is OK as stated above, I do not know what is wrong, but if I have access to the server I can figure it out by Googling and checking the server configuration. We do not see this error on any of our test servers nor on my local installation.

Problem is solved.

There was an additional attribute "targetFrameWork" with the value "4.5.1" in the compilation node in the Web.config.

On the server Framework 4.5.2 was installed and that seems to supersede 4.5.1

Removing that attribute resolved the problem.
