这段时间在迁移旧项目到teamcity，在package *.vdproj project时遇到了这个错An error occurred while validating. HRESULT = '8000000A'
查了很多方法才解决这个问题

stackoverflow上给出的权威解答是这样的：

Unfortunately we couldn’t address all cases of the command line issue for this release as we’re still investigating the appropriate way to address them. What we do have is a workaround that we believe will work for almost all of them.
If you are still suffering this issue then you can try to change the DWORD value for the following registry value to 0:
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0_Config\MSBuild\EnableOutOfProcBuild (VS2013) or HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0_Config\MSBuild\EnableOutOfProcBuild (VS2015)
If this doesn’t exist you can create it as a DWORD.

但是我的agent vm 有很多台，于是写了个script

#add_registy_procbuild_ps.ps1
$ProcBuildRegistryPath = "HKCU:\Software\Microsoft\VisualStudio\14.0_Config\MSBuild"
$ProcBuildRegistryName = "EnableOutOfProcBuild"
$ProcBuildValue = "0"

"Add DWORD paramter for Proc build registry..."
IF(!(Test-Path $ProcBuildRegistryPath)) {
     "Add:"
     New-Item -Path $ProcBuildRegistryPath -Force | Out-Null
          New-ItemProperty -Path $ProcBuildRegistryPath -Name $ProcBuildRegistryName -Value $ProcBuildValue `
               -PropertyType DWORD -Force | Out-Null }
ELSE {
     "Modify:"
     New-ItemProperty -Path $ProcBuildRegistryPath -Name $ProcBuildRegistryName -Value $ProcBuildValue `
          -PropertyType DWORD -Force | Out-Null }

then execute this script in cmd

1
powershell -ExecutionPolicy ByPass -File \\172.16.xx.xx\c$\script\add_registy_procbuild_ps.ps1

Good Job, 完美解决~
