I have taken over a project that is targeting .net4.
One of the projects within the solution is using System.Runtime.CompilerServices.CallerMemberNameAttribute from the System.Runtime.dll that is installed when you are using the Microsoft BCL Portability Pack.
I have checked and the project is currently using version 1.1.3.
When the solution is build on local dev machines, everything compliles with no problems.
I am now trying to get the solution built in teamcity, but when TeamCity attempts to compile the solution I am getting this error.
error CS0246: The type or namespace name 'CallerMemberName' could not be found (are you missing a using directive or an assembly reference?)
error CS0433: The type 'System.Runtime.CompilerServices.CallerMemberNameAttribute' exists in both 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' and 'c:\apps\teamcity\buildAgent\work\bb8aacaa9fabeac8\packages\Microsoft.Bcl.1.1.3\lib\net40\System.Runtime.dll'
I have read Jon Skeets answer to this question: Using CallerMemberName attribute in a portable library But I am already using the BCL library.
After spending some time on this, I found another question answered by Jon Skeet that resolved this issue.
When must we use extern alias keyword in C#?
Within my project, after getting the links to the Package, for each dll I had to change the name of the alias. ie from global to newglobal
Then in the classes that where using the CallerMemberName, had to do the following
At the top of the page, above the using statements
extern alias newglobal;
And then when referencing CallerMemberName, enter the code as
[newglobal::System.Runtime.CompilerServices.CallerMemberName]
This allows the code to be successfully built on teamcity where .net 4.5 has been installed.

In my Blazor application, on the client side, IntelliSense complains about a lot of Microsoft.AspNetCore packages although the project compiles and runs fine.
I get a lot of things like
The type or namespace name 'Mvc' does not exist in the namespace 'Microsoft.AspNetCore' (are you missing an assembly reference?)
The type or namespace name 'Razor' does not exist in the namespace 'Microsoft.AspNetCore' (are you missing an assembly reference?)
...
Things like
#inject HttpClient Http
are also underlined with red squigglies.
The project builds and runs perfectly.
What is wrong here?

Because I was asked for all versions:
Visual Studio 2019, 16.0.2
Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview4-19216-03
In my project:
Id Versions ProjectName
-- -------- -----------
Microsoft.AspNetCore.Blazor.Build {3.0.0-preview4-19216-03} MyBlazorApp.Client
Microsoft.AspNetCore.Blazor {3.0.0-preview4-19216-03} MyBlazorApp.Client
NETStandard.Library {2.0.3} MyBlazorApp.Client
You need Visual Studio Preview version 16.1 or higher to work with 3.0.0-preview4 Blazor.
If that alone doesn't help, verify that you dont have any .cshtml files in your client project - they all have a .razor extension since 3.0.0-preview4. The presence of .cshtml file triggers a different SDK's behavior, requiring AspNetCore.Mvc namespace. Though Microsoft guys see it as a bug and probably will fix it.

Shut down VS
Delete the .vs folder or the .suo file
Restart VS
uninstalling x86 version of .NET Core 3.0 Preview SDK
https://dotnet.microsoft.com/download/dotnet-core/3.0
Then installing the x64 again on Windows10 64bit fixed that issue for me
I'm attempting to use the following command line command to compile an assembly of the code from my project:
C:/"Program Files"/Unity/Editor/Data/Mono/bin/gmcs
-target:library -out:C:/Users/Austin/Desktop/PixelExpanse.dll
-recurse:C:/Users/Austin/Desktop/Projects/Repos/trunk/PixelExpanse/SpaceColonyRefactor/Assets/Source/*.cs
-d:RUNTIME -r:C:/"Program Files"/Unity/Editor/Data/Managed/UnityEngine.dll
As you can see, I am, I believe, correctly referencing the UnityEngine.dll.
The code that would be compiled contains references to UnityEngine.UI and UnityEngine.EventSystems. But when I run the above command, I get the following compile error:
error CS0234: The type or namespace name 'EventSystems' does not exist in the namespace 'UnityEngine'. Are you missing an assembly reference?
From what I have been able to find through googling, it SEEMS like an error people were getting when using a pre-4.6 assembly, because thats when EventSystems and UI were both introduced. But I don't know how I could be missing that in the dll I'm referencing as Unity 5 is the only version that has ever touched this computer.
As a side note, I have posted this question to Unity Answers and have yet to receive a response. I expect it's because assembly compilation is beyond the scope of what most users there choose to undertake. Hence my asking it here.
The namespace UnityEngine.EventSystems actually appears in UnityEngine.UI.dll and not UnityEngine.dll so it seems you need to reference the former too when compiling manually from the command-line. Unity projects have this by default (see below).
This is verified by opening up the assembly in your reflector tool of choice, here I am using JetBrains dotPeek:
This is how my test project appears with default Unity references. Note that by default a reference to UnityEngine.UI already appears in the Unity-created project:
When I built my Windnows desktop app via Unity, the above dlls appeared in:
<drive>:<projectOutFolder>\<projectName>_Data\Managed
You can try:
right click on "project panel", and after "Reimport All".
It's can be happen due to switch between platforms, e.g. IOS, or Desktop.. thus, folrders are deleted by became unecessary..
Solve for me: Unity 5.2, Win 7, 32bits;
Good luck!
I checked the UnityEngine.dll and the Eventsystems/UI namespace is not included. Despite, there is a dll in Unity5\Editor\Data\UnityExtensions\Unity\GUISystem\UnityEngine.UI.dll which includes these namespaces.
For mac, it's /Applications/Unity/Unity.app/Contents/UnityExtensions/Unity/GUISystem/UnityEngine.UI.dll.
I am using MVC 5, C#, .NET 4.5.1 in Visual Studio 2013. Following a Microsoft/Windows Update yesterday (15 October 2014) my program refuses to compile with multiple errors of the two types below:
The type or namespace name 'Mvc' does not exist in the namespace 'System.Web'
The type or namespace name 'ControllerContext' could not be found (are you missing a using directive or an assembly reference?)
I have tried this on a different computer (also with the patches) and had the same errors. The program in question is in production and compiled perfectly before the changes.
Before I start uninstalling and restoring the different patches, has anyone else seen this problem and is a solution/workaround known.
I got the same error yesterday. I assumed it was something I had done. One of the projects in our solution had a reference to System.Web.Mvc 4.0.0.0 and it could no longer find it. I updated that project using NuGet to System.Web.Mvc 5.2.0.0 (which is what all the other projects in the solution were using anyway) and all was well.
I am trying to run a C# console application on my server which is running Ubuntu Server 12.04. I have installed Mono JIT version 2.10.8.1 (Debian 2.10.8.1-1ubuntu2.2) and additional packages like gmcs and MonoDevelop. The file that I am trying to execute is called Program.cs and when I run the command $gmcs Program.cs I get the following errors:
error CS0234: The type or namspace name 'Tasks' does not exist in the namespace 'system.Threading'. Are you missing assembly reference?
error CS0246: The type or namespace name 'MySql' could not be found. Are you missing a using directive or an assembly reference?
error CS0246: The type or namespace name 'MySqlConnection' could not be found. Are you missing a using directive or an assembly reference?
I have researched into referencing the .dll files for the above namespaces but have not been able to find an answer that is clear. Most forum links suggest that I install mono - trunk, but I want to know if I should uninstall the existing mono package and then install mono-trunk.
I am new to the Unix platform and researching every step of my way. Your help will be much appreciated.
If you are compiling from the command line, you will need to pass the referenced assemblies as a series of /r or /pkg switches, such as:
mcs /r:MySql.Data.dll Program.cs
Obviously you will need to have the required assemblies installed too.
Also note that gmcs is an (old) alias for the .net 2.0 compiler, that's why it doesn't see System.Threading.Tasks (which is a .net 4 feature). See the -sdk switch of mcs.
You should probably install monodevelop to have a user-friendly IDE to help you.
I am new to StreamInSight development. I have downloaded few samples and now I am trying to compile them. I am getting error as "The type or namespace name 'IQStreamable' could not be found (are you missing a using directive or an assembly reference?)" I have already included below references into my project -
Microsoft.ComplexEventProcessing
System
System.Reactive.Core
System.Reactive.Interfaces
System.Reactive.Linq
System.Reactive.PlatformServices
System.Reactive.Providers
Please let me know if I am missing anything.
You need to make sure that the version of StreamInsight you downloaded and installed is v2.1. The IQStreamable interface is new in v2.1. Once you have confirmed that you have the correct version of StreamInsight or installed the correct version, you'll need to make sure you have the appropriate namespace and assembly included with your project. IQStreamable is in the Microsoft.ComplexEventProcessing.Linq namespace and the Microsoft.ComplexEventProcessing.dll. It also would not hurt to make sure that you are running the most recent version of Rx.
