I have a project using DevExpress 8.3 (2008.3) which I just recently upgraded to use VS 2010. After doing so, everything compiled fine but I got errors trying to use the designer. I resolved this as described here: http://stackoverflow.com/questions/2637089/netfx40-legacysecuritypolicy-in-design-time-mode
by adding <NetFx40_LegacySecurityPolicy enabled="true"/> to my devenv.exe.config.
Designer works fine now, but some of the projects in the solution which have COM references no longer compile, with the exception:
The "ResolveComReference" task could not be instantiated from "Microsoft.Build.Tasks.v4.0, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". The security state of an AppDomain was modified by an AppDomainManager configured with the NoSecurityChanges flag.
The COM references for those projects are also flagged with a yellow exclamation mark.
The only google result I found for this error was here: http://social.msdn.microsoft.com/Forums/en/vsx/thread/197b8dca-5610-4ac5-86fc-c56d5182e46b
which describes the exact same problem but with no resolution. I tried adding
<GenerateResourceNeverLockTypeAssemblies>true<GenerateResourceNeverLockTypeAssemblies>
as the post suggests but that doesn't have any effect for me.
Anyone know anything about this?
Thanks.
