`PowerShell.Create()` returning null
(3 answers)
Closed last year.
I migrated from .NET Framework 4.8 to .NET 6.
System.Management.Automation.PowerShell.Create();
now returns null.
Is there a new package i need to reference or other solution?
Removing the old References and adding the NuGet package
Microsoft.PowerShell.SDK solved this issue.

HttpUtility does not exist in the current context
(10 answers)
Closed 5 years ago.
I'd like to use HttpUtility.HtmlDecode() to process some strings in my application, but for some reason Visual Studio doesn't seem to know where it's at.
I'm fairly new to C# so I'm just guessing I've missed something like importing a library, but I don't even know what to Google.
I've tried using System.Web but it only seems to contain AspNetHostingPermission and friends, no HttpUtility.
I'm using VS2015 Community Edition on a Windows 10 machine.
I've tried "using System.Web" but it only seems to contain "AspNetHostingPermission" and friends, no HttpUtility.
You simply need to reference the DLL System.Web, right click References > Add Reference > Assemblies > Framework > System.Web
Also check you're not targeting the Client Profile, in which System.Web.dll is not available. You can target the full framework in Project Properties.

Closed 6 years ago.
When I start a new empty project there is an error in the .net core project:
Controller is a namespace but is used like a type.
Am I missing some packages?
You're right, you've missed Microsoft.AspNetCore.Mvc package. Just add it to project.json and things will be OK.

But I keep getting error message mentioning the tables are not created by code first.
I did not find any clue mentioning sqlite ef6 nuget package can or can not do this.
If not, what would be other options you recommend for in memory databases.
I would be thankful if you help.

LINQ on the .NET 2.0 Runtime
(8 answers)
Closed 9 years ago.
I made an application in .net framework 4.0, visual studio 2010, but due to some reason i changed the framework from 4.0 to 2.0 but now i am getting error that
The type or namespace name 'Linq' does not exist in the namespace 'System' (are you
missing an assembly reference?)
LINQ is very much used in this project, now i want to know that is there any way to use LINQ with .net 2.0.Need help.Thanks.
Linq is not supported in dotnet 2.0
You can use LinqBridge, which provides an alternative implementation of the Linq to Objects operators. (note: it works only for Linq to Objects, not for Linq to XML or Linq to XML...)

What are the correct version numbers for C#?
(13 answers)
Closed 8 years ago.
I am confused with both the C# version and .NET framework version. In other words, I want to know the relationship with C# version and .NET framework. E.g: which is C# version in .NET framework 3.0?
I am not sure what your actual question is, but if it is what are the current versions..
C#: 3.0
.NET Framework: 3.5
You might also want to take a look at this breakdown chart. It provides the Framework, language and CLR relations.
C# 1.0 - Managed Code
C# 2.0 - Generics, Nullable Types, Anonymous Delegates, Partial Classes / Methods
C# 3.0 - LINQ, Lambda Expressions, Implicit Variable Typing, Streamlined Object Initialization
