This also occurs on v4.9.0 - although this is an existing test installation and an upgrade of Contour using the files in the upgrade zip & SQL script

Hi guys, could you tell me if you have .net framework 4.5 installed? Might be related to that, looking into the issue now

Hi Tim,

We are just using the 4.0 framework.

So the 4.5 framework isn't installed on the machine you are running the site on? From what I can find it has something todo with that, I'll let you know once I find a solution

Installing the 4.5 framework should resolve the issue but I'm looking into a solution that doesn't need that...

Thanks Tim,

I'm just setting up a test system based on working backups of our existing test installation. I'll upgrade again with the standard 4.0 framework, then try installing version 4.5 if I get any problems. I'll let you know how I get on!

Hi Tim, I'm also using the 4.0 framework.

@Tucker, thanks , currently installing .net framework 4.5 should resolve the issue but I'm also looking into a fix

Hi Tim, I've just installed .net framework 4.5 and Contour 3 looks to have installed correctly, I'll shout if I have any problems! Thanks for your help.

@Tucker, thanks for confirming!

@Kumar you need to install the .net framework 4.5 if you see that error

Hi Tim,

That means it doesnt work in the .net framework 4.0  ?

@Kumar it should but currently it doesn't due to an issue on our build server, we are looking into it but currently the only way to fix is to install .net framework 4.5

Thank you tim..

May i know which Contour version's are compatable with the .net 4.0...?

@Kumar versions before 3.0

 thanq TIM

I will do that...

i just upgraded an existing contour to v3 and i have the same problem - issues in the back-end and all xslt failing on the front-end.

presumably related to this thread: http://our.umbraco.org/forum/getting-started/installing-umbraco/34986-Umbraco-49-Could-not-load-type-'SystemRuntimeCompilerServicesExtensionAttribute'-

 UPDATE:

upgrading the server to .net 4.5 seems to have fixed the issue.

Tim - is it possible to have a .net 4 version of contour?

Hi Tim
