Answer 1

You just need to upgrade your .NET framework to ver 4.5 in your IIS 7.5 server you do that using the Microsoft web installer do a search for .NET and then installed the .NET framework version 4.5 and the all the apps that target that version will work

Answer 2

Chances are IIS doesn't have 4 installed (or if it is the site isn't specified to use it). Assuming you're running IIS7 have a look at this post:

Answer 3

you have to install .net framework 4.5 then it will works fine. "targetframework" attribute is not recognized by .net framework 4.0. So run the following command on command prompt and check either .net version 4.5 in installed on hosting machine or not.if not then install .net framework 4.5.it will work fine. run this command on cmd as follows.

wmic /namespace:\\root\cimv2 path win32_product where "name like '%%.NET%%'" get version

Answer 4

I had similar issue installing nopCommerce 2.80 on server. I use IIS7 net. 4.0 integrated pool. And just installed .net 4.5 from WebMatrix Products->Frameworks section. Restart will be required. Then it started to work.

Answer 6

Change this tag to 4.0:

<compilation targetFramework="4.0" />

and remove this tag:

<httpRuntime targetFramework="4.5" />
