VS .NET Project file not read only after build

[Steve Wright]

I have taken the continuous integration build sample and customized it for my needs. I am having a problem with my VS .NET project file not having a read only attribute on the second pass thru the loop. I make sure that all of the project files (multiple projects in solution) are set to read only before starting VBP. The first pass works: it detects VSS changes and downloads what is needed. It builds the project fine and then waits. On the second pass it dies while getting VSS changes. For example, I get:

A writable copy of c:\projects\ADETCA\ADETCA_Lib\ADETCA_Lib.csproj already exists

Note: I have checked the "Restore read-only attribute..." in the VSS build step under the "Project/Solution" tab.

TIA,
Steve
