Introduction. When we develop web- based solutions, usually, we are in charge of updating the installations to use a current version. We fix some bugs, add a feature, make a patch, and deploy it so that our customers can continue using our software without interruption. But when we have clients installing our software, we still need to give them updates.
Even standalone applications have problems with results from old versions. If an application connects to an external system to push or pull data, the problems can be even worse - even resulting in data loss.
Consumers of your application are busy people and they don't always remember to check for updates to your software. Why do I need an updater?
We wanted a . NET solution that would allow our clients to use the most current version of our software. We had been having problems with a mobile app synching its data across multiple versions, so we enacted a policy to only allow a sync operation from the most current version of the software. This meant that we would have to have a way of easily and quickly updating remote installations.

What does it do? In short, the Launcher checks the update location for version changes, downloads and unpacks any updates, and then executes the main application. If there aren't any version updates or the update location is not available, the Launcher simply executes the current version of the main application. How can I write one?
We'll be writing this in . NET 4. 0, using Visual Studio 2. C#. The unit tests are written in Visual Studio Team Test. A unit test framework of your choice may be used, but the walk through below will use the commands in Team Test. We store the current version information in a text file.
The file is present in the update location, and after an update is successfully downloaded and unpacked, it is saved to the client. When the client's text file and the update location's text file match, the launcher knows the current version is up to date. If they don't match, we'll need to download the update and unpack it. Since our archive can contain multiple files, it'll be easier to use a decompression library other than GZip to unpack it. We'll be using the Ionic Dot.
Net. Zip library (http: //dotnetzip. Let's create our new project. Create a new WPF Application called Article.
Auto. Updater. Our procedures are small in scope and could easily reside within the application itself, but of course you were going to fully unit test the code, right? It's easier to test a class library, so let's create it. What does the version text file look like?
As we can see, this is a very simple file. It is one line and all it contains is a full four- value version number. This is only one approach to recording the version.
You could also use Reflection or a file system call to identify the version of a particular file, but we're using this file approach so that we can include updates of files that aren't always managed assemblies or even applications. How do we check our versions?
Let's start by creating a Class Library called Application. Update. Rename the default Class. Versions. Change it to a public static class, since our version operations are all argument- driven. The first procedure we'll write is to check a version file for the current version number.
We know that we need to check two files: one remote via URL, and one local via file path. Let's start with the local version. Local. Version(string path).
Now let's create our unit tests for our method. Our first test case is to open a non- existent file and make sure the version returns null. Let's write a test for it. Right- click the method and click Create Unit Tests..
Make sure the Local. Version method is selected and select "Create a new Visual C# test project.. Click OK. Name your new project Application. Update. Test. Now rename the test it just generated from Local. Version. Test to Local. Version_Bad. File_Test, since we'll be testing for a bad file.
Since the test framework generated such a nice test for us, we'll just plug some values in and remove the inconclusive line. We'll also check to make sure path doesn't actually point to a real file, since that would invalidate the test.[Test. Method()]. publicvoid Local.
Version. Test(). string path = @"C: \Bad. Folder\Bad. Version. File. version". Assert. Is. False(new System. IO. File. Info(path). Exists. "File should not exist."). Versions. Local. Version(path).
Assert. Are. Equal(expected, actual). Run the test and make sure we have a failure.
Assert. Are. Equal failed. Expected: < (null)>. Actual: < >.
This is exactly what we expected. Now let's code our method. If the path points to a file that doesn't exist, we want to return null. That's easy enough, so let's make it happen. Local. Version(string path). System. IO. File. Info(path). Exists).
Run the test again. Pass! Let's add a couple more bad paths to the test and make sure they all fail. We'll add a drive that doesn't exist, a string that doesn't look like a path, and a null value. All of these are good failure cases. Our test ends up looking like this: [Test.
Method()]. publicvoid Local. Version_Bad. File_Test(). C: \Bad. Folder\Bad. Version. File. version". Assert. Is. False(new System. IO. File. Info(path).
Exists. "File should not exist."). Versions. Local. Version(path).
Assert. Are. Equal(expected, actual). Z: \ASDcjaksl\fasjldjvalwer".
Versions. Local. Version(path). Assert. Are. Equal(expected, actual). Versions. Local. Version(path). Assert. Are. Equal(expected, actual). AVEW VRLQ#". actual = Versions. Local. Version(path). Assert. Are. Equal(expected, actual).
Case 2, path = @"Z: \ASDcjaksl\fasjldjvalwer", passes already. For case 3, path = null, we need to do a little validation. We'll just add string. Is. Null. Or. Empty(path). Local. Version(string path). Is. Null. Or. Empty(path) ||.
System. IO. File. Info(path). Exists).
The null path passes! We are still failing on illegal characters, though. LINQ to the rescue! Add one more condition: System. IO. Path. Get. Invalid. Path. Chars(). Intersect(path. To. Char. Array()).
Count() != 0. Now Local. Version looks like this: publicstaticstring Local. Version(string path). Is. Null. Or. Empty(path).
System. IO. Path. Get. Invalid. Path. Chars(). Intersect(. To. Char. Array()). Count() != 0. || !
System. IO. File. Info(path). Exists). And all of our tests are passing. Success! Of course, it's inefficient to keep getting a new File.
Info for every operation - it's just for coding simplicity. Afterall, these tests are pretty small in scope and only do a handful of operations.
If you'd like to write them such that they use a single File. Info instance, please feel free to. It's time to move on. Now let's open a file that's really there and make sure we handle it correctly. Right- click the method and click Create Unit Tests.. Make sure the method and the test project are selected, and click OK.
Now rename the test to Local. Version_Good. File_Test. Let's use the test to actually create (and clean up) a version file so that we know it is testing accurately. Let's not do anything fancy - we'll create a folder and drop the file there.[Test. Method()]. publicvoid Local.
Version_Good. File_Test(). Path = "C: \\Versions.
Test". if (! new System. IO. Directory. Info(folder. Path). Exists). System. IO. Directory. Create. Directory(folder. Path). string file. Name = "app. version".
Path + "\\" + file. Name. string expected = "1.
System. IO. File. Info(path). Exists). System. IO. File. Write. All. Text(path, expected). Assert. Is. True(new System. IO. File. Info(path).
Exists. "File should exist now."). Versions. Local. Version(path). Assert. Are. Equal(expected, actual). When we run this, it fails. We expected this, and now we know we aren't accidentally retrieving something. Let's finish up this method. Local. Version(string path).
Is. Null. Or. Empty(path). System. IO. Path.
Get. Invalid. Path. Chars(). Intersect(.
To. Char. Array()). Count() != 0. || ! System. IO. File. Info(path). Exists). System. IO. File. Info(path). Exists).
System. IO. File. Read. All. Text(path). Is. Null. Or. Empty(s)). Trim(). }And our test passes! But what happens if we try to use a file that isn't our version file?
We want the version to return null because the file we are checking does not serve our purpose.[Test. Method()]. publicvoid Local. Version_Good. File_Test(). Path = "C: \\Versions.
Test". if (! new System. IO. Directory. Info(folder. Path). Exists). System. IO. Directory. Create.
Directory(folder. Path). string file. Name = "app. version".
Path + "\\" + file. Name. string expected = "1. System. IO. File. Info(path). Exists).
System. IO. File. Write. All. Text(path, expected). Assert. Is. True(new System. IO. File. Info(path). Exists. "File should exist now.").
Versions. Local. Version(path). Assert. Are. Equal(expected, actual). C: \Program Files\Microsoft Visual " +. Studio 1. 0. 0\Common. Tools\errlook. exe". Versions. Local. Version(path). Assert. Are. Equal(expected, actual, "This is not a good version file!").
We need to validate it! Refactor the code that creates the file and writes it. We'll use this later. Create. Local. Version.
File(string folder. Path. string file. Name, string version). System. IO. Directory. Info(folder. Path). Exists). System. IO.
Directory. Create. Directory(folder.
Path). string path = folder. Path + "\\" + file.
Name. if (new System. IO. File. Info(path). Exists). new System. IO. File. Info(path). Delete(). if (! new System.
IO. File. Info(path). Exists). System. IO. File. Write. All. Text(path, version).
Update your tests to run Create. Local. Version. File instead of duplicating this code. Time for another method. Create your shell: publicstaticbool Validate.
File(string contents). Now create a unit test.
First things first - let's check a valid version string.[Test. Method()]. publicvoid Validate.
File. Test(). string contents = "0. Versions. Validate. File(contents). Assert.
Are. Equal(expected, actual). And we fail. Regular Expression time.
