Resharper DotCover Analyse for Visual Studio Team Services

Do you use Visual Studio Team Services (VSTS) for Builds and/or Releases? Do you use Resharper DotCover? Do you want to use them together? Then boy do I have an extension for you!

That might be a corny introduction, but it is exactly what I have here.

In my current projects we use Resharpers, or also know as Jet Brains, DotCover to run code coverage on all our code. However to run this in VSTS there is a bit of a process to install DotCover on the server and then write a Batch command to execute it with settings. This isn’t the most complex task, but it does give you a dependency to always install this on a server, and have the written Batch script in source control or in the definitions on VSTS. This can cause issues if you forget to get it installed or you need to update the script for every project.

Therefore I got all that magic of the program and cramed it into a pretty package for VSTS. This tool is not reinventing the wheel, but putting some greese on it to run faster. The Build/Release extension simply gives you all the input parameters the program normally offers and then runs them with the packaged version of DotCover that comes with the extension. See simply.

There is however one extra bit of spirit fingers I added into the extension. When researching and running my own tests, I found that some times it is helpful to only run the coverage on certain projects, but to do this you need to specify every project path in the command. Now I don’t know about you, but that sounds boring, so I added an extra field.

Instead of in the Target Arguments passing each project separately and manually, you can pass wildcards in the Project Pattern. If you pass anything in the Project Pattern parameter it will detect you want to use this feature. It then uses the Target Working Directory as the base to recursively search for projects.

For Example: Project Pattern = “*Test.dll” and Target Working Directory = “/Source”

This will search for all DLL that end with ‘Test’ in the ‘Source’ directory and then prepend it to any other arguments in the Target Arguments.

For Example: “/Source/MockTest.dll;/Source/UnitTest.dll”

You can download the extension from the VSTS Marketplace

Update 20-07-2018

There was a recent issue raise on the GitHub Repository that addressed a problem I have also seen before. When running the DotCover from Visual Studio Team Services an error appears as below:

Failed to verify x64 COM object registration: Empty path to COM object.

From the issue raise, the user had linked to a Community Article about “DotCover console runner fails when running as VSTS task“, which in the comments they discussed how to fix this.

To correct it we simply add the following command to the request, that specifies what profiled process bitness to use as they say.


Therefore the task has now been updated with this field and feature to accomadate this issue and fix. It has been run and tested by myself plus the user that raised the issue, so please enjoy.

How to get the users IP Address in C#.NET?

When you search this on your favourite search engine, (Google) you will get flooded by load of different way to get the end result. This is great in a sense as you know there are thousands of people with different answers, but then that is where the problem is at. There are so many single responses to how you can get the users IP Address in C#.NET, but not one that shows you everything. Therefore I will present to you below different methods to get the users IP and how I have implemented it in a project.

All the methods I found to be best are using the Request Server Variables. These are predetermined environment variables and request header information. This is why you can get IP address as it is part of the header information.

The standard server variable to use is ‘REMOTE_ADDR’, which is done as the following:


However if the user is behind a proxy server, then the above will return that IP Address and not the actual users. The server variable to get the users IP address from behind the proxy server is ‘HTTP_X_FORWARDED_FOR’ done as below:


Then you get that issue of not knowing if the user is behind a proxy or not, as the first example will return one or the other and the second example will only return a value if there is a proxy server. Therefore we need to find out if there is a proxy server or not. You can do this with the server variable ‘HTTP_VIA’, if this has a value then they must be using a proxy server and so you can get the correct IP as below:

If (HttpContext.Current.Request.ServerVariables[“HTTP_VIA”] != null) {
return HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

return HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

Or another method is to do it in reverse and check if the proxy method is not null first instead like:

string userIp = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

if (string.IsNullOrEmpty(userIp)){
return HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

return userIp;

This is the best method I found to get the users IP Address in ASP.NET C#, but if you think there is a better way then please comment below with your solution.

How to Force clear cache

As all developers know our best friend and worst enemy is the cache. You can make all your changes and be confident they will work, then they don’t change just when you want them to. It is great that you can clear your own cache, but how can you refresh all the users cache? Here are some of the methods I know of and used.

Bit of a FYI part, this is focused to JavaScript on a Windows server running IIS, but some of these methods can be used on multiple languages.

Query string

First up is the query string method. When the browser caches the file it caches the URL for it location. This included the query string of the URL. It makes it like the key to the value, so if you change the key then it needs to get a new value.

For Example:

The query string can be anything, so you could even just put the number.

For Example:

You can then make this dynamic my appending the build number of your deployment. This however is dependent on who, what and where your file is. Unfortunately as well, some browsers don’t use the whole URL. They cut the Query string off for the Key part of the cache. This means this method doesn’t work for some browsers.

IIS URL Rewrite

This can be done in IIS and also using the .htaccess on an apache server. For this you will need to install the IIS URL Rewrite tool from Microsoft.

The use of this is to rewrite the directory of the URL instead, so unlike the previous method it would work in every browser.  The only issue I have found with this is I don’t know how to add a version number on there without having to physically add a number on the end for each deployment. You can however also use this in the web.config of the application, where you might be able to dynamically get the number of the build.

Here is how to use the URL Rewriter:

Restart Application Pool

This is a more indirect method. You can force user to get a new copy of the site if you restart you application pool in IIS, but this would clear the whole site so if you just changed one JavaScript file they will be getting more than they needed. This can then be worst for the users that are on their mobile phones as it then takes more data to get the whole site.

If you are ok with this then you could also script a PowerShell script to restart the applications at will. This can be done with dunning iisreset from an elevated (on Vista/Win7/Win2008) command prompt, which will restart IIS and in turn restart all the application pools.

These are just some method that can used and there are also other way to use the premises, but in maybe better ways for your application. If you have any other methods please comment them below and share the knowledge.

MS Word special characters Regex

That pesky Microsoft! They have to be different and mess us developers around don’t they. Have you ever noticed that Microsoft Word’s symbols look a bit different or act a little odd? Well it’s because they are not the standard char characters. This can be a pain for Regex and other things. So how do you get them…

The reason they are so difficult is they use Windows-1252 character encoding set which are not represented in ASCII or ISO-8859-1. This is what just about everyone doesn’t do of course. These characters include:

  • … ellipsis
  • ‘smart’ “quotes”
  • en – dash and em — dash
  • dagger † and double dagger ‡

There are few more of course, but these are the most common few that come up. You can find more of Microsoft Word Windows-1252 character encoding here.


Symbol Encoding
single quotes and apostrophe \u2018\u2019\u201A
double quotes \u201C\u201D\u201E
ellipsis \u2026
dashes \u2013\u2014
circumflex \u02C6
open angle bracket \u2039
close angle bracket \u203A
spaces \u02DC\u00A0


Here is a pre-built method for JavaScript and C# to combat these.


JavaScript Clean String

var wordClean = function(text) {
var cleanStr = text;

// smart single quotes and apostrophe
cleanStr = cleanStr.replace(/[\u2018\u2019\u201A]/g, “\'”);

// smart double quotes
cleanStr = cleanStr.replace(/[\u201C\u201D\u201E]/g, “\””);

// ellipsis
cleanStr = cleanStr.replace(/\u2026/g, “…”);

// dashes
cleanStr = cleanStr.replace(/[\u2013\u2014]/g, “-“);

// circumflex
cleanStr = cleanStr.replace(/\u02C6/g, “^”);

// open angle bracket
cleanStr = cleanStr.replace(/\u2039/g, “<“);

// close angle bracket
cleanStr = cleanStr.replace(/\u203A/g, “>”);

// spaces
cleanStr = cleanStr.replace(/[\u02DC\u00A0]/g, ” “);

return cleanStr ;

C# Clean String

public string wordClean (string text){
var cleanStr  = text;

// smart single quotes and apostrophe
cleanStr  = Regex.Replace(s, “[\u2018\u2019\u201A]”, “‘”);

// smart double quotes
cleanStr  = Regex.Replace(s, “[\u201C\u201D\u201E]”, “\””);

// ellipsis
cleanStr  = Regex.Replace(s, “\u2026”, “…”);

// dashes
cleanStr  = Regex.Replace(s, “[\u2013\u2014]”, “-“);

// circumflex
cleanStr  = Regex.Replace(s, “\u02C6”, “^”);

// open angle bracket
cleanStr  = Regex.Replace(s, “\u2039”, “<“);

// close angle bracket
cleanStr  = Regex.Replace(s, “\u203A”, “>”);

// spaces
cleanStr  = Regex.Replace(s, “[\u02DC\u00A0]”, ” “);

return cleanStr ;

If you are doing some validation using Regex, here is also how you can check these characters.

JavaScript Regex

function containsWordChar(text) {
var contains;

switch (text) {

case (text.match(/^[\u2018\u2019\u201A]$/)):
contains += “single quotes and apostrophe, “;

case (text.match(/^[\u201C\u201D\u201E]$/)):
contains += “double quotes, “;

case (text.match(/^[\u2026]$/)):
contains += “ellipsis, “;

case (text.match(/^[\u2013\u2014]$/)):
contains += “dashes, “;

contains += “circumflex, “;

case (text.match(/^[\u2039]$/)):
contains += “open angle bracket, “;

contains += “close angle bracket, “;

case (text.match(/^[\u02DC\u00A0]$/)):
contains += “spaces, “;

contains += “double quotes”;


return contains;

C# Regex (MVC)

[RegularExpression("^[\u2018\u2019\u201A\u201C\u201D\u201E\u2026\u2013\u2014\u02C6\u2039\u203A\u02DC\u00A0]+$", ErrorMessage = "Your content contain some Microsoft Word Windows-1252 character encoding.")]

C# Regex

Public string containsWordChar(text) {
String contains;

switch (text) {

Scale Azure SQL Database with PowerShell

In the pursuit to move to Azure we have had the need to scale the SQL databases. Your company may only have high or any traffic during certain times or even certain season. We need the best solution during working hours so this is what I have based it off.

The program will take the database you want to scale and then you can set it to be whichever setting you require. So lets begin…

The first step is to install the necessary programs and plugins. These are

  • Install Azure Power Shell
  • Install Command-Line tools

These can be downloaded from The Azure Downloads Section.

Now we get into the PowerShell scripting part. The first section is to get the credentials for the database server. There are two method to this that I have found.

The simplest and securist method is to use ‘Get-Credential’. This will promote you for the username and the password for the database, that will be used later for the authentication.
$DBname = "protech"
$creds = Get-Credential

The other method is less secure as you will have your username and password stored in the file unencrypted. Though this is the best method to then have it automated with out the need for user interaction.
$DBname = "database"
$username = "username"
$password = "password"

$secstr = New-Object -TypeName System.Security.SecureString
$password.ToCharArray() | ForEach-Object {$secstr.AppendChar($_)}
$creds = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $secstr

This section then gets the connection to the database. This is where it will use your ‘creds’ variable and also the full name to the database. You can get this by following the step guide on How to find the Fully Qualified Azure SQL Database Name. In the example below I have put ‘’
$serverContext = New-AzureSqlDatabaseServerContext -Credential $creds -FullyQualifiedServerName
Other methods to get the Server Context are on the Microsoft Website.

Finally you can connect to the database using you ‘serverContext’ and the chosen ‘DBname’.
$db = Get-AzureSqlDatabase $serverContext –DatabaseName $DBname
Below are how to change to the different Azure SQL Database Tiers. I have added how to change to each one, so you will just have to chosen which you would like.

Scale Azure SQL Database to Basic

$b = Get-AzureSqlDatabaseServiceObjective $serverContext -ServiceObjectiveName "Basic"
Set-AzureSqlDatabase $serverContext –Database $db –ServiceObjective $b –Edition Basic

Scale Azure SQL Database to tandard 1

$S1 = Get-AzureSqlDatabaseServiceObjective $serverContext -ServiceObjectiveName "S1"
Set-AzureSqlDatabase $serverContext –Database $db –ServiceObjective $S1 –Edition Standard

Scale Azure SQL Database to Standard 2

$S2 = Get-AzureSqlDatabaseServiceObjective $serverContext -ServiceObjectiveName "S2"
Set-AzureSqlDatabase $serverContext –Database $db –ServiceObjective $S2 –Edition Standard

Scale Azure SQL Database to Standard 3

$S3 = Get-AzureSqlDatabaseServiceObjective $serverContext -ServiceObjectiveName "S3"
Set-AzureSqlDatabase $serverContext –Database $db –ServiceObjective $S3 –Edition Standard

Scale Azure SQL Database to Premium 1

$P1= Get-AzureSqlDatabaseServiceObjective $serverContext -ServiceObjectiveName "P1"
Set-AzureSqlDatabase $serverContext –Database $db –ServiceObjective $P1 –Edition Premium

Scale Azure SQL Database to Premium 2

$P2= Get-AzureSqlDatabaseServiceObjective $serverContext -ServiceObjectiveName "P2"
Set-AzureSqlDatabase $serverContext –Database $db –ServiceObjective $P2 –Edition Premium

Scale Azure SQL Database to Premium 3

$P3= Get-AzureSqlDatabaseServiceObjective $serverContext -ServiceObjectiveName "P3"
Set-AzureSqlDatabase $serverContext –Database $db –ServiceObjective $P3 –Edition Premium

An issue I found was the once I had saved the PowerShell file it wouldn’t run. There would be permissions issue to run the program, so to get round this if you run the below script first it will give you the permissions to run the code.
