   SlimDX: Support for .Net 4.0?
  I'm trying to update a SlimDX application to 4.0; however, I'm running into an "{"Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.":null}" error.Any help would be appreciated, as would an estimate of when 4.0 might be supported.   
  you need to recompile SlimDX for .net 4.0.  If you attempt to compile the samples then you need to change their setting as well. Other than that, SlimDX works fine with 4.0.   ;  You need to rebuild SlimDX from source, targetted against 4.0. I hear this is difficult because the DirectX SDK does not support VS2010 yet, but I have not tried. There's also some manifest trickery you can work, but I'm not familiar with those yet either.We will not support .NET 4.0 until VS 2010 is released (not RTM), and the DX SDK does. The earliest you can expect to see it is the next SDK release, which will be shortly after the next DX SDK release.   ;  Thanks.   ;Quote:You need to rebuild SlimDX from source, targetted against 4.0. I hear this is difficult because the DirectX SDK does not support VS2010 yet, but I have not tried. Really? I've been using 2010 with the Feb. SDK since it came out, and I don't have any problems. Well, for native C++ development anyway.;  http://blogs.blackmarble.co.uk/blogs/rfennell/archive/2010/03/27/mixed-mode-assembly-is-built-against-version-v2-0-50727-error-using-net-4-development-web-server.aspxYou just need to add useLegacyV2RuntimeActivationPolicy="true" to your app.config and it will work. I've been using SlimDX in a DX10 .Net 4.0 RC setup for awhile now with no problems :)   ;  Thanks again; I'll try that.   ;Quote:Really? I've been using 2010 with the Feb.

Well, for native C++ development anyway.I only read that in passing on the MSDN forums, so it's quite possibly wrong (I've had very bad luck with those forums providing useful and accurate information), which I why I mentioned I'd hadn't tried it. I'm glad it's not the case, because that would have made our job harder.   ;  I couldn't find the file specified in the "Common Files" folder. In addition, would there be a way to specify that setting for just the project?   ;  I could not, in fact, find that file anywhere; nor was there a file like it.It could be because I'm cash-limited to the Express version. In any case, I still need a work-around.
