This is without much information and a generic error, might require tearing your hair out a lot, trying to resolve.
How to resolve
This could be easily a firewall blocking access to your SQL server, or firewall not allowed IP for your Azure database server. Fix could be easy as adding the required firewall exceptions.image

Build C# 6 Syntax with TFS 2013.4 Build Services

If you are using VS 2015 with C# 6 syntax and try to build it with, TFS 2013.4 (build agent installed with VS 2015 Update1 enterprise) you might run into issues like shown below.
The name 'nameof' does not exist in the current context01
This error occurs, since TFS 2013.4 build template is using, msbuild 12.0. To let the TFS build to use msbuild 14.0, you can provide msbuild argument /ToolsVersion switch (or /tv, for short), in TfvcTemplate.12.xaml build process template.
With this the previous error solved but now it runs into below issue.
TF900547: The directory containing the assemblies for the Visual Studio Test Runner is not valid ''image
To solve this install VS 2013 in build agent. It solves the problem.03
Tests in here fail, but that is nothing to do with build. Tests are not properly written.
You might run into below issue as well.
Unhandled Exception: System.TypeInitializationException: The type initializer for 'LibGit2Sharp.Core.NativeMethods' threw an exception. ---> System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

--- End of inner exception stack trace ---
at LibGit2Sharp.Core.NativeMethods.RemoveHandle()
at LibGit2Sharp.Core.NativeMethods.LibraryLifetimeObject.Finalize()x

This is discussed in below links and you can solve using different techniques described in them.

Deploy dacpac with MSDeploy in VS Release Management

To deploy a dacpac against a target database, MSDeploy can be used. In powershell, following command allows to deploy a dacpac.
Invoke-Expression "& 'WebDeployFolderPath\msdeploy.exe' --% -verb:sync -source:dbDacFx=`'SourceDACPAC`' -dest:dbDacFx=`'DestinationDBConnection`',commandTimeout=100"  -Verbose -ErrorAction "Stop"
.\DeployDacpacMSDeploy.ps1 -WebDeployFolder "C:\Program Files (x86)\IIS\Microsoft Web Deploy V3" -SourceDACPAC "C:\temp\MyDb.dacpac" -DestinationDBConnection ",1433;Database=mydb;User ID=dbadmin@qa-db;Password=pwd;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30" -CommandTimeout 100
A poweshell script can be developed, to use in a Release Management tool.image

$ErrorActionPreference = "Stop"

Invoke-Expression "& '$WebDeployFolder\msdeploy.exe' --% -verb:sync -source:dbDacFx=`'$SourceDACPAC`' -dest:dbDacFx=`'$DestinationDBConnection`',commandTimeout=$CommandTimeout"  -Verbose -ErrorAction "Stop" | Out-Host

if ($lastexitcode -ne 0) 
        throw "Dacpac deploy failed."
Using this poweshell script a tool in RM can be created as shown below.01
Using the tool, create an action component.02
This component can be used in a release template.03
Database updates can be pushed to Azure SQL or any other target SQL server.04

Run xUnit Unit Tests for (dnx)ASP.Net 5 with VS Team Services Build

To run the xUnit unit tests developed for ASP.Net 5 (ASP.Net Core 1.0 now), you need to setup a powershell step/task. Setting up a build with VS Team Services, for ASP.Net 5 is explained here.
First thing we need is a powershell script, which can runt xUnit tests, in VS Team Services build. (Hardcoded paths and project names in the script)

Set-ExecutionPolicy unrestricted -Scope CurrentUser -Force

$VerbosePreference = "continue"
$ErrorActionPreference = "Continue"
&{$Branch='dev';iex ((new-object net.webclient).DownloadString(''))}
$globalJson = Get-Content -Path $PSScriptRoot\..\..\EventBooking\global.json -Raw -ErrorAction Ignore | ConvertFrom-Json -ErrorAction Ignore
    $dnxVersion = $globalJson.sdk.version
    Write-Warning "Unable to locate global.json to determine using 'latest'"
    $dnxVersion = "latest"
& $env:USERPROFILE\.dnx\bin\dnvm install $dnxVersion -Persistent
$dnxRuntimePath = "$($env:USERPROFILE)\.dnx\runtimes\dnx-clr-win-x86.$dnxVersion"

dnx -p $PSScriptRoot\..\..\EventBooking\BookMyEvents.UnitTests test 
Check this script in.image
We have to make sure test results are available to publish in the build. for that we can change the test project .json to create a results xml.image
Next add a powershell script task/step to the build. Set the script to execute and let it continue on error, to make sure, it will not break the build on a test failure.image
To publish the results, use “Publish Test Results” step. Set the test results xml file name specified in the project .json, for the results files. Select the Test result format as XUnit.image
Once a build queues it executes the test and publish the results.image
When there are multiple tests running in the build, a detailed test report helps to identify which tests fail.image
