Force CLR Version
-
My dll is built in 2.0 Framework but still its using runtime 4.0 while consuming in the application. I need to force my dll to use CLR Runtime version 2.0 instead of 4.0. Is there any way to do it.
You cannot force a .DLL to use a specific CLR version. The code will run under whatever the CLR version the .EXE is using. .DLL's are loaded into the process the same as any other code in the .EXE. If you want to change which version of the CLR the code uses, you have to specify that in the application manifest file. How to: Configure an Application to Target a .NET Framework Version[^]

Have you tried adding a
supportedRunTimeelement to the application's configuration file? See http://msdn.microsoft.com/en-us/library/w4atty68(v=vs.80).aspx[^] I can't tell from the documentation if this would force a particular version of the CLR to load, but it would be worth doing an experiment to find out. Alan -

No am not using any assemblies from 4.0 framework and it is targetting to 2.0 framework.
Then your assembly will work on .NET 2.0 (and up!); which runtime it uses depends on the app that consumes the assembly, and all it's references. I do not see a problem with it running on CLR 4.0. Do you?

Do you mean app.config file? Even though I specify in app.config but my deliverable is only dll so it dnt work out for me.
Sorry, yes, app.config. config files only work with .EXE's. You cannot make an app.config for a .DLL file. The .DLL is loaded as part of the .EXE as if it was in the same file as the .EXE. That's why config's only work with .EXE's and not .DLL's. If you want your .DLL to run with a certain CLR version, the .EXE that's loading it ALSO has to run with that CLR version.

Hi Dave, I have to creat only class library which is using in JNI(java). So I have specify target version through my class library code. Is there any way to do this.
Again, no. The only way to do that is to specify it in the app.config of the HOST .EXE that is loading your .DLL. Why can't your .DLL run under the .NET 4.0 CLR??

Dave KreskowiakI am using Microsoft.Dynamics.BusinessConnectorNet with this which is compiled in 2.0 version. My dll works fine in .net environment where i can set supportedruntime in appconfig. But when dll goes to JNI it is running under the latest .net framework i.e 4.0 installed in that system and giving the mixed mode assembly exception .

Well, we've told you the only way to do it, and you've even said that you've tried it and it works ("supportedruntime in appconfig"). The only other option you have to to get an updated Dynamics library and compile a second version of your .DLL that works with the .NET 4.0 CLR.
