I saw a few questions related to this on stack overflow but none of them helped. I am using VS 2019 community edition, I created an API project on .NetCore 2.1, and added the following nuget packages. (assuming all EF packages will be included by default)
Microsoft.EntityFrameworkCore.SqlServer
Microsoft.EntityFrameworkCore.Design
After some time into the coding I needed to use MapToStoredProcedures in the OnModelCreating function..But its not available,
entitytypebuilder doesnot contain a definition for maptostoredprocedures
after looking for a few solutions, i tried to
install-package Microsoft.EntityFrameworkCore.Relational
which did not work as there was a version conflict issue...
NU1202: Package Microsoft.EntityFrameworkCore.Relational 3.0.0 is not compatible with netcoreapp2.1 (.NETCoreApp,Version=v2.1).
then i tried to install SDK and restart VS, then i again tried to install Microsoft.EntityFrameworkCore.Relational nuget package but the same error was there.
Finally, I installed:
Microsoft.EntityFramework (6.3)
and an older version of Microsoft.EntityFrameworkCore.Relational (2.1.11)
which was successful but the MapToStoredProcedures function is still unavailable.
the using statement in the class also doesnt show Microsoft.EntityFrameworkCore.Relational namespace...
I am very confused as this function used to be available in VS 2013 with EF 6. :S
So i realize that EF 6 used to have the MapToStoredProcedures function and EF Core doesn't have it. (Not sure why they decided like that).
I changed my target framework to netcoreapp3.0 from netcoreapp2.1 and then i was able to install Tools and Microsoft.EntityFrameworkCore.Relational packages.
Finally, I am calling my sp as follows:
var dbResults = _gecontext.ParameterDetails.FromSqlRaw("EXEC dbo.get_nextParamSummary #UserId={0}", userId).ToList();

When i try create new blank application in nanoframework, i get package installation error.
error message
It seems some problem in nanoframework visual studio extension, my version is NET nanoFramework VS2019 Extension v2019.5.0.8.vsix, but i also tried another versions with same problem.
I have visual studio 2019 community edition and i have installed almost all components.
When i press ok, project is loaded, but is not possible compile it, because there are missing all assemblies. When i try add assembly, theres nothing to add and add nuget packages from nanoframework store leads to error.
when i try this:
pm> Install-Package nanoFramework.CoreLibrary.NoReflection -Version
1.10.1-preview.9
I get this error:
NU1202: Package nanoFramework.CoreLibrary.NoReflection
1.10.1-preview.9 is not compatible with netnanoframework10 (.NETna noFramework,Version=v1.0). Package
nanoFramework.CoreLibrary.NoReflection 1.10.1-preview.9 supports: net
(.NETFramework,Version=v0.0)
similiar when i try another package versions.
So the extensions is installed incorectly, but i cant find why. i tried it more times. uninstall and install again. from extenstion store, and from disc. nothing successfull.
The webserver NuGet released today fixes the issues with the version mismatches.
The issue with VS2019 16.9 remains. Reported to VS Developer Community here. Please up vote to help increase priority.
What is the Community version you're using?
After a little test, there seems to be an issue with the latest release of VS2019. A work around would be to:
Use V16.8.X
or
use an already created solution that you can edit.
or
add the required nuget to the project once it has been loaded (after the error):
Update: now fixed! it was due to a change to fix nuget, but caused an unintended consequence with nanoFramework.
I developed an ASP.Net MVC web application and It's almost completed. After That, I updated Bootstrap through NuGet package manager to Bootstrap latest stable version 4.3.1 Update was successfully completed. But after the migration following errors are occurred.
Error Build:Cannot find name 'Record'.
Error Build:Cannot find name 'undefined'.
To solve that I installed TypeScript for Visual Studio 2015. Then the above error solved and the following error occurred.
Severity Code Description Project File Line Suppression State
Error The build task could not find node.exe which is required to run
the TypeScript compiler. Please install Node and ensure that the
system path contains its location. ABH.SW.HotelManagement
How can I solve this? I tried to google it for the past 2 days but I wasn't able to find any solution
This is the only post for this problem, so I'll do my bit for those who use Bootstrap 4.3.1, TypeScript, and VS2015.
First, once you create the project and are about to install Bootstrap 4.3.1 through NuGet, don't let Visual Studio manage TypeScript Typings for you. Check no.
Once Bootstrap and stuff is installed, clean the solution: right click on your solution -> clean solution
Next, open NuGet console (Tools → NuGet Package Manager → Package Manager Console), and install TypeScript 3.0 using this command:
Install-Package Microsoft.TypeScript.MSBuild -Version 3.0.0
Close Visual Studio, open it again, and that's it. Took for me a lot of research to find out that several TypeScript versions cause a lot of conflicts and 3.0 is one of those that actually work.
I had the same issue while trying to update to Bootstrap 4 from Visual Studio 2015. What fixed it for me was installing Typescript 2.2 for Visual Studio 2015 (https://marketplace.visualstudio.com/items?itemName=TypeScriptTeam.TypeScript22forVisualStudio2015). You may need to uninstall previous versions of Typescript Tools for VS2015 from Programs and Features.
I think Bootstrap 4.3.1 , Typescript , VS2015 has some issues with each other.
[e.g.
Compilation error from Angular and typescript in VS 2015 MVC project

My scenario in my project got this error

I'm using VS2017 while other team member that has problem using VS2015 with TypeScript Tools for Microsoft Visual Studio 2015 3.2.2.0 installed
He told me that after map project from source control there is and alert message of something like his typescript version is newer. So after some googling I think you should look in to this link for more information

For Vs2015 + Bootstrap 4.3.1 I solved my issue by

In my Asp .Net Core Web Application (started with empty template) I cannot install Microsoft.AspNet.Mvc nuget package.
After pressing Install in Nuget manager I get this error message:
Package restore failed. Rolling back package changes for 'WebApplication1'.
I tried to solve it on my own, but:
1) My project doesn't have project.json
2) Clearing nuget cache like in this answer didn't help:
Netstandard1.x Nuget packages cannot be installed for netstandard1.x projects
Project target framework: .NetCoreApp1.0 (also tried 1.1)
Ide: VS2017 RC
I didn't have problems so far with installing other packages.
Is there a workaround to install mvc package?
Btw. I have to start with empty project template.
Thanks in advance for your support.
I looked harder in nuget package name and discovered that correct package to install should be Microsoft.AspNetCore.Mvc and not Microsoft.AspNet.Mvc.
Silly mistake, I chose most popular package by typing "mvc" in search box.
I'm using VSCode and Paket to add libraries from Nuget to an F# project/.fsproj file.
From VSCode, I use ctrl+shift+p and use the command Paket: Add Nuget Package (to current project) and enter
FsVerbalExpressions version 0.4.0
Unfortunately, Paket fails with the following error:
Paket version 3.23.2.0
Adding FsVerbaExpressions 0.4.0 to
c:...\paket.dependencies into group Main
Resolving packages for group Main:
- FsVerbaExpressions is pinned to 0.4.0
Package not available.
Message: Couldn't get package details for package FsVerbaExpressions 0.4.0 on https://www.nuget.org/api/v2.
Paket failed with:
Could not find versions for package FsVerbaExpressions on https://www.nuget.org/api/v2.
I know that FsVerbalExpressions is available on Nuget. I need the older version because the project I'm working on is targeted at .NET 4.5 and the newer version of FsVerbalExpressions will only work with .NET 4.6.1.
Typos happen. Make sure you proofread your error messages before looking for answers that are already in front of you.
I created a new Project in Visual Studio 2013, a WebApi & MVC 5 project and updated all nuget packages. It updated to mvc 5.1. Now I cannot Successfully build the project it says
assembly uses System.Web.Http 5.1.0.0 which has a higher version than referenced assembly System.Web.Http 5.0.0.0
Anyone run into this before? Why these kind of problems do occur so often in Visual Studio? Does anybody know how to solve this because I really am trying hard but no luck so far...
Solved
I opened the Package Manager Console in Visual Studio and run the command
PM> Update-package
It magically resolved everything for me. You can find Package Manager Console under
Tools
Nuget Package Manager
Package Manager Console
This command deletes all the old packages under the package folder and updates everything if necessary, you may also run the command on a specific package. Here all the variants of the command http://docs.nuget.org/docs/reference/package-manager-console-powershell-reference#Update-Package
Let me know if you found this useful I'm curious to know if it just happened to me accidentally
A new version of ASP.NET was released. Announcement here : http://blogs.msdn.com/b/webdev/archive/2014/01/20/announcing-the-release-of-asp-net-mvc-5-1-asp-net-web-api-2-1-and-asp-net-web-pages-3-1.aspx
You probably have two projects in your solution, where project A references project B. Both projects reference ASP.NET, but there is a version mismatch.
I had a very similar problem to yours exactly with a reference to System.Web.Http and have documented it here:
Could not load assembly error
When you update a Nuget package it would update dependent packages. But it would not update other packages in your solution that depend on the updated packages. These other packages might not even have a newer version built with the udpated packages.
So the solution is either to udpate all your packages like you did (this might not always work) or add binding redirects to the latest version of your assembly reference to your application config.
I solved this way. As I currently have fwk 4.0.0.0 and don't want to install 5.X:
I removed the referenced DLLs
I removed a couple of bindingRedirects at packages.config,
Then I rebuilded that solution, that throws me errors
Then I added the reference again
And voilà, the solution is running with the fwk that I have.
