I ran into a problem and started learning ASP.NET (dotnet 7) when creating a migration, an error occurs Build failed. Use dotnet build to see the errors. image1 image2 image3 image4 image5
If you comment out the code line
var connectionString = builder.Configuration.GetConnectionString("DefaultConnection");
builder.Services.AddDbContext<ApplicationDbContext>(
options => options.UseSqlServer(connectionString));
then the error remains the same, I created the database and tried to unload it with a username and password, the error is the same, I checked it in the console application, visual studio shrunk from the database

I wanna publish my app to my friends,and make for them installation as easy as possible so my app use SoundPlayer which needs file to play the sound. My question is how can I know where will they have this file saved?
I used this code:
SoundPlayer music = new SoundPlayer(ApplicationDeployment.CurrentDeployment.DataDirectory + #"\songfolder\Main.wav");
That gives me error: The application identity is not set.
PS: sorry for my bad English :D
Are you talking about publishing projects via ClickOnce? You can go to Project -> Properties -> Publish and check if the required files are included in Application Files.
Solution Explorer:
Application Files:
And you need to use the following code to access these files.
string filepath = AppDomain.CurrentDomain.BaseDirectory + #"songfolder\song.mp3";
Last, click Publish Now to publish it.

After building the release version for my application, I went to the bin/Release folder and saw a bunch of my project dependencies, such as "Newtonsoft.Json.dll", "System.Memory.dll" and so on.
I have referenced posts like What files are mandatory in release windows form? and saw that these dependencies are needed for my application to run smoothly.
However, I only needed to copy one file - my "main.dll" to the application (I'm creating an add-on for Revit) and it works fine. So, I'm wondering which files could be excluded? This is because my application is still being modified and new dependencies are being added, and I would like to know which files are not needed.
Is there a list of dependencies that have already been included in windows automatically?
In short, you probably need them all and sometimes some. The long version -- it depends. Below is not an exhaustive list but some points to consider:
Whatever is part of the .NET framework that you are using is not normally copied to the output directory
The examples that you listed normally should be copied to the output as they are not part of .NET Framework
You can force a reference to be copied by setting Copy Local to true, which would result in a potentially unnecessary DLL in your output directory
You may have some dependencies in the GAC, which means they might not be copied to the output directory. For example, are you using Infragistics, etc. controls -- do all of your users have them installed on their machines? Probably not and they probably shouldn't, so include them...
The compiler is generally smart about not including things to which you have no actual code references (this can lead to problems if there are dynamic invocations only)

I am implementing some functionality which pulls data through the scripting code which is below:-
<system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="300000"/>
</webServices>
</scripting> </system.web.extensions>
I add the above code in the web.config but it gives me error as
500 Internal server error.
However it works fine on my local server. I have no idea what wrong is happening.
Got the Issue cleared. It was just the framework issue.
I changed as described by the My birth name i changed the IIS settings accordingly and it worked fine.
STEPS
Open IIS.
Right Click on the Site/Virtual Dir. Select PROPERTIES
Select the Asp.Net Tab
Select the .Net version from the dropdown.
Click SAVE
I changed the Framework from v2.0 to v4.0

I have a project within my solution aimed to store my model.ecmx file for EF. This is not the solution's start up project. This project has an App.Config file in it.
I have another App.Config file in the solutions start up project.
The connection string is defined in both App.Config files.
Is this correct?
If each project can use the same App.config, you could simply have a single copy in one project, and include it in the others as a "link", instead of a unique file.
Do include a file as a link, just keep one copy of it across your projects, and then go to each project and do "Add" -> "Existing File". When selecting the file, drop down the "Add" button instead of clicking it, and choose to add as link:
If they can't share the same App.config, you can use the syntax to use a separate config file for the connection strings, and then include that file as a link.
Example of second option:
Main app.config:
<connectionStrings configSource="other.config">
</connectionStrings>
Note that the connectionStrings element above must be completely empty when using configSource.
Then other.config:
<?xml version="1.0"?>
<connectionStrings>
....
</connectionStrings>
This pattern can be used for many config sections, not just connectionStrings.
Or, Rahul notes another great option; you could define the connection string at a higher level, such as machine.config. That might make deployment a little more complex, but works more simply.
