I am calling this command as a prebuild event from one of the project
"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\tfsbuild" start "tfs-server" "project name" "Build definition name"
Error: Microsoft (R) TfsBuild Version 10.0.0.0 for Microsoft Visual Studio v10.0 Copyright (c) Microsoft Corporation. All rights reserved.
TF215036: The build request cannot be queued at or below position 1 on build con troller Euphrates. The resulting position would be 2.
On tfs their is not a single build running
Please help thanks
