Hello Thanks for quick reply ! I'm almost 100% sure thet this is different problem than that is described in JIRA issue... If i understand this, msbuild task project has reference set on wrong version of Microsoft.Build.Utilities.dll assembly 1) There exists old version of that assembly located somewhere in mbunit source tree and that assembly is in project referencies 2) You have still installed some beta of .NET 2.0 and project is referencing assembly from it (but this is unlikely - i even don't know if .NET 2.0 RTM can coexists on same machine with beta versions....perhaps not)
Solution is very easy. Remove old reference from project and add new reference - Microsoft.Build.Utilities.dll is showing on the very first tab in 'Add assembly reference' dialog (.NET tab)....because it is installed in gac Now. i'm looking on mbunit source from trunk and case number one is correct - there are local copies of msbuild assemblies....I'll try build the task with correct referencies.....after the work :) HTH Liwoj
