Problem after install of 2-3-8-1

Here's the process I took:

I installed mojoportal-2-3-8-1-mssql-net40-deploymentfiles.zip

I changed the server to .Net 4.0 (Discountasp.net)

This worked.

However, I realised that updating to this version of .Net caused me issues with my own custom web services which are compiled under .Net 3.5, and since I use Visual Studio 2008 I can't develop in .Net 4.0

So I attempted to downgrade to the same package version (as well as re-setting the server .Net version to a maximum of 3.5 SP1) .

I upgraded to .Net 3.5 using this file:

mojoportal-2-3-8-1-mssql-net35-deploymentfiles.zip

After this I get this error:

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

I did a quick google search and turned up that it's about Azure cache. This link (in another language - but the translation through google seems good).

This one too:

In short it looks like it can be corrected by changing the reference however I don't have time for this so I'm going back to my old version for the moment. I bet this works perfectly in 3.5 mode on a server that also has 4.0 running.

Re: Problem after install of 2-3-8-1

Hi,

Just delete any dlls it complains about from the /bin folder

Some files are only included in the.NET 4 package, but downgrading did not remove them.

You can probably qualify to get VS 2010 free via the Microsoft Website Spark program. When .NET 4.5 ships later this year we will probably drop support for .NET 3.5, also there are medium trust problems under .NET 3.5 that affect design and skinning. .NET 4 works better.

Hope that helps,

Joe

Thanks. I'll try that. I'll let you know the outcome.

I'm in the process of getting VS 2010 installed shortly anyway.
