How to Get the Physical Path of an ASP.NET Application

-
This is one of those things I do infrequently enough that every time I need to, I ask myself "Now how do I do that again?". So I'm posting this here not only to help anyone else who needs to do this, but also to be able to easily remind myself how next time I need to.

To get the physical path of an ASP.NET application, you can use:
HttpContext.Current.Request.PhysicalApplicationPath

How to Get Norton Security Suite Firewall to Allow Remote Desktop Connections in Windows

-
Image
I ran into an issue recently with RDP connections being blocked by the firewall in Norton Security Suite. I checked the traffic rules under Settings > Firewall > Traffic Rules  and found that it was enabled by default (and couldn't be edited): But during further research, I found  this page  on Norton's support site which discusses the different trust levels of networks and mentions that, for the Public trust level, "This setting also blocks remote desktop connections by default.". I checked my network's trust level, and sure enough, it was set to Public (I'm not sure how/why). (Sidebar: Notice in the screenshot above that allowing Remote Desktop for Public Networks is defaulted to Allow , though that rule is not active). Here's what my network trust level looks like now after changing the setting to Private (accessible under Settings > Firewall > General Settings > Network Trust ): After changing the network trust level t...

Resolving the "n timer(s) still in the queue" Error In Angular Unit Tests

-
A few months ago one of the developers I work with ran into the below error in an Angular unit test: 1 timer(s) still in the queue The fix was to specify a particular amount of time in the tick() call as shown below: it( 'should set accountConfirmationDetails when getAccountConfirmationDetails is called' , fakeAsync(() => {          // Arrange          let  spyGetAccountConfirmationDetails = spyOn(accountService,  'getAccountConfirmationDetails' )         .and         .returnValue(Promise.resolve(AccountMockData.mockAccountConfirmationDetails));                    // Act         fixture.detectChanges();   ...

How to Determine if a Column Exists in a DataReader

-
I recently had to work on something which required me to query a database, open the results in a DataReader, and check for the existence of a particular column. While the DataReader doesn't have a method to do this, with just a few steps I was able to accomplish this task. Here's how. First, the DataReader has a method named GetSchemaTable() , which returns a DataTable consisting of information regarding the data contained in the DataReader. The first column in this DataTable is named ColumnName , and its value is (obviously) the name of the column. Knowing this, we can loop through the rows in the DataTable, checking the ColumnName column for a value that equals the name of the column we're looking for. To this end, I wrote a static method in one of my classes which takes the DataReader and the name of the column being sought: (C#) public static bool HasColumn(DbDataReader Reader, string ColumnName) {    foreach (DataRow row in Reader.GetSchemaTable().Rows)  ...

Silent Renew and the "login_required" Error When Using oidc-client

-
I recently implemented the Silent Renew functionality of oidc-client in an Angular application I work on, and was getting reports that the users' tokens were still expiring. This made no sense to me as I'd verified the code was working during development, but yesterday I found the problem and am hoping it will save someone some time. The error we were getting back was "Error from signinSilent: login_required". This indicates that the user's session is no longer active on IdentityServer and they must re-authenticate -- which, of course, is what we're trying to prevent by using Silent Renew. In our case, the problem wasn't with the Silent Renew functionality, but rather the user's session was expired. The reason why  it was expired was because, for some reason, we were setting the session length to 15 minutes instead of the default 10 hours . What was occurring was that Silent Renew was attempting to renew a token after 55 minutes (60 minutes expirat...

Unit Testing with a Mock Entity Framework DbContext and Fake DbSets

-
I'm a big fan of the Repository pattern, and use it hand-in-hand with dependency injection and the Query Object pattern. Lately I've been developing with Entity Framework, and using dependency injection to pass the DbContext instances into my repository classes. But one of the issues I ran into while trying to unit test one of my repository classes is that I couldn't figure out how to mock the DbSets that my DbContext exposes. I could create a mock of the DbContext, but was having trouble setting it up to return fake collections of entities. One of the problems is that DbSet has no constructor (it's created via a factory method). After much research and scouring of the web, here are the steps I learned to accomplish this.   Step One: Create a Fake DbSet Class That Implements IDbSet The DbContext exposes entities in DbSets. DbSet, in turn, implements the IDbSet interface. So we can create a class for use with our unit tests that, unlike DbSet, can be instantiated on ...
