I am trying to use Ubuntu 18.04 to test some things, and I can use any of the newer .NET Core SDKs.
I just installed a fresh VM with 18.04, and installed my usual tools. I then try and build SkiaSharp, and then the .NET Standard projects and Tizen fail to build with the same error.
I can roll back to dotnet-sdk-2.1.105, and that seems to work fine. As soon as I go later, then it fails. I tried installing a different version of dotnet 2.2, but I only have one for some reason. Sure, I could install it manually and all that. But, who wants to do that — and I am not even sure it is going to work.
Here is my apt-search output: https://gist.github.com/mattleibow/935de7d22b24cfcf3ae9ab0c16b1908f
What is the reason for these failures? My code was working — as it is building just fine with 2.1.105, and then I bump up just a fraction and boom?

Your combination of Mono MSBuild and .NET Core SDK is incompatible because they use different versions of the internal NuGet library. To resolve this problem, you can:
- Downgrade .NET Core SDK to 2.1.5xx or 2.2.1xx (for example, 2.1.505 or 2.2.108)
- Upgrade Mono to 6.0

This appears to be a known issue.
The only fix at this stage seems to be to downgrade to .NET Core v2.2.105.
To downgrade:
- Uninstall the latest .NET Core version (v2.2.2+).
- Download and install v2.2.105.

Run the following CMD in the *.sln folder. This will delete all your OBJ and BIN folders automatically. And your issue will be solved.

I had the same problem in migration from .Net Framework 4.5 to .NET 6.0 (with the 70 project).
All of the above answers are correct, but they were not enough for my problem.
I use this answer:
Deleting the
binandobjand.vsfolders then Clean Solution and
Rebuild Solution
it’s working in Build Mode, not Rebuild. And the problem remained.
I update the
VersionofSDK, but not enough and I have the problem.
I realized this:
duplicate property(or variables) with the same name (or similar Name) inderivedclasses.
It was a good solution and a few problems were solved.
finally (after the 3 days), The biggest problem I noticed was that I had Loop References.
I fixed The Loop References in projects and the error is solved.

Change the name of the file. For instance, Add prefix _ or #; so, it cannot be used.
Restart Visual Studio, then try to build. If still problem is there, needs to restart the machine.

I had this error happen and the slove for me was correcting the Package version number in .csproj file .
<Version>2.0.7.</Version> <!--casued the error-->
<Version>2.0.7</Version> <!--this fixed the error-->
Removing the trailing ‘.’ fixed this for me.

I recently ran into a compilation error that is preventing me from building and running my WebAPI. It was working perfectly just the night before, so I’m very confused as to why it’s happening now with no changes. My target framework is «netcoreapp3.1».

Hi,
We know this problem and we are tracking this as an issue that needs fixing. In the mean time can you try this workaround and tell us if it resolves the problem for you?
Edit your project file and add this to the first PropertyGroup:
<GenerateResourceNeverLockTypeAssemblies>true</GenerateResourceNeverLockTypeAssemblies>
That should get rid of this error. Tell us what you find.

This appears to be a known issue.
The only fix at this stage seems to be to downgrade to .NET Core v2.2.105.
To downgrade:
- Uninstall the latest .NET Core version (v2.2.2+).
- Download and install v2.2.105.
Change the name of the file. For instance, Add prefix _ or #; so, it cannot be used.
Restart Visual Studio, then try to build. If still problem is there, needs to restart the machine.
I had this error happen and the slove for me was correcting the Package version number in .csproj file .
<Version>2.0.7.</Version> <!--casued the error-->
<Version>2.0.7</Version> <!--this fixed the error-->
Removing the trailing ‘.’ fixed this for me.
I had .net standard project built on .net standard 2.0. Yesterday I updated my Visual Studio 2019 to 16.3.0 to leverage .Net Core 3.0. But all of sudden build of project targeting on standard 2.0 started throwing «GenerateDepsFile» task failed unexpectedly error.
I was able to resolve this issue by changing the target framework to 2.1.
If you have <DelaySign>false</DelaySign> in your .csproj file remove it to solve this Problem.
in vs code i got this error, after trying some solution from forms, i found solution in deleting bin and obj foldersfrom project and build again.
this solved my problem.
vs code version: 1.53.1
dotnet version : 5
Run the following CMD in the *.sln folder. This will delete all your OBJ and BIN folders automatically. And your issue will be solved.
FOR /d /r . %%d in (bin,obj) DO ( IF EXIST "%%d" ( ECHO %%d | FIND /I "node_modules" > Nul && ( ECHO.Skipping: %%d ) || ( ECHO.Deleting: %%d rd /s/q "%%d" )))
I had it after updating vs 2019 community,
Delete bin & obj folders,
then clean & build the solution.

This issue happens whenever I add the dll of the solution in to the references through «browse»
However, once removed, the program still doesn’t seem to run just as a standalone .exe
