I'm new to C# althought have experience with other programming languages.
I am trying to get this demo code to build:
https://github.com/MicrosoftDocs/SimpleRecorder
I've installed Visual Studio 2019 free edition plus I installed everything else I thought might possibly be needed such as the.NET framework.
One of the errors is as follows:
Severity Code Description Project File Line Suppression State
Error CS0234 The type or namespace name 'Capture' does not exist in the namespace 'Windows.Graphics' (are you missing an assembly reference?) CaptureEncoder C:\Users\andrewstuart\devel\screenrecorder\CaptureEncoder\CaptureFrameWait.cs 9 Active
But many other errors appear in the Visual Studio log when I try to build the project. Here's a screenshot:
Can anyone suggest what I might be doing wrong and how to get this project to build?
thanks
First and foremost, I've never worked with C#, or any compiled language for that matter. So I'm hoping I'm just doing something wrong here.
We have an old in house app, written in c# that has some smtp settings hard coded that need to be changed. I have the source files, and even the .sln visual studio project file. So I open the project in vs, make the required changes, and go to build- however I'm running into errors (Build -> Build 'Autodocs' (the name of our app)):
Build started...
1>------ Rebuild All started: Project: AutoDocs, Configuration: Debug Any CPU ------

1>C:\shared\New folder\AutoDocs\AutoDocs\modules\DWStorer.cs(7,7,7,15): error CS0246: The type or namespace name 'DocuWare' could not be found (are you missing a using directive or an assembly reference?)
========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========
So does anybody have any suggestions for a c# newbie like me? Anything I should have to do when copying a project dir from the server to my pc to build it?
Thank you in advance.
Do you know what kind of program it is? Windows? ASP.NET? MVC?
The errors are shown, but let's go through them:
1>C:\shared\New folder\AutoDocs\Microsoft\Office\Interop\Word\Documents.cs(10,38,10,54):
error CS0234: The type or namespace name 'CustomMarshalers' does not exist in the
namespace 'System.Runtime.InteropServices' (are you missing an assembly reference?)
First, look in this document:
C:\shared\New folder\AutoDocs\Microsoft\Office\Interop\Word\Documents.cs
Somewhere in that file, when viewing in Visual Studio, you will see the word CustomMarshalers, and it needs to be referenced.
So, in your project, you will need to right-click the References section and add that missing reference (if it isn't there already):
Also, at the top of your Documents.cs file, you need to have a line like this:
using System.Runtime.InteropServices;
See Microsoft's documentation here: System.Runtime.InteropServices.CustomMarshalers
Here is your second error:
>C:\shared\New folder\AutoDocs\AutoDocs\modules\DWStorer.cs(7,7,7,15):
error CS0246: The type or namespace name 'DocuWare' could not be found
(are you missing a using directive or an assembly reference?)
Similar to the first error, this one is having an error in the DWStorer.cs file because it cannot resolve the keyword DocuWare.
DocuWare is a third party tool that must be added to your references and added to the top of your DWStorer.cs file.
DocuWare
You may have to go to the link above to download their tool if you do not have it in your project somewhere.
how i can fix this problem??
help me
Compiler Error Message: CS0246: The type or namespace name 'MySql' could not be found (are you missing a using directive or an assembly reference?)
Line 1: using MySql.Data.MySqlClient;
Apologies if this is not the case but working on the assumption that you're developing in a version of Visual Studio, check the project references.
If MySql.Data exists in the references but has the warning (yellow triangle) indicator next to it then you may need to re-reference the .dll from its location in your filesystem.
Alternatively, you can grab this from the Nuget package manager if it is not available locally.
Despite the full namespace qualification, the library must be correctly referenced for the object namespace to be recognised in the IDE.
Let us know what IDE you're using if not VS.
I am using asp.net core web application with Visual Studio 2015. I have added a reference project and implemented the method which is working fine.
Here is the screen shots
Now I have removed the dependency from project.json and deleted the project.lock.json file. I have completely removed the reference.
When I completely remove the reference I am still able to use UserViewModel and Go to definition opens the file in metadata. But I cannot use the JwtTokenViewModel.
The error details
error CS0246: The type or namespace name 'JwtTokenViewModel' could not be found (are you missing a using directive or an assembly reference?)
I did some research and found that we get cs0246 error is due to reference problem. I have followed the solution of some link but not a solution
Why am I getting error CS0246: The type or namespace name could not be found?
How can I resolve this issue. Please anyone let me know.
Whenever I take the latest code from TFS and tries to build existing solution, It fails all the project building and says that : The type or namespace name 'XYZ' does not exist in the sampace 'a.b.c' (are you missing an assembly reference?)
This is happening with all the references and only in my system. On the other systems all these code works fine.
Can it be a Visual Studio issue or some setting which might have got changed?
