How can I use VSTS to build projects developed in Visual Studio .NET 2003 on version 1.1 of the .NET framework?
See Nagaraju Palla’s blog entry: Building binaries targeting .NET 1.1 and .NET 1.0 in TeamBuild. Alternatively, you can try MSBee, an addition to MSBuild that allows developers to build managed applications in Visual Studio 2005 that target .NET 1.1, which is supported on the Developer Aftermarket Solutions and Powertoys forum.
