I'm using Visual studio 2013 and I'm want to compile my project for linux (with MONO).
Is this possible to use VS2013 (with or without mono plugin) to compile my project to MONO file?
Yes, you'll be fine to use VS to build a .NET project that can run against Mono.
You'll be fine with the stock csc compiler and MSBuild (as both csc and the Mono compiler generate CIL all the same) just make sure that your project references Mono's assemblies rather than .NET's where there are breaking differences (e.g. System.Windows.Forms, etc). If you're doing ASP.NET or Console applications you should be fine without doing anything special.
As long as you use the versions of the DLLs that come from nuget instead of the references that are added by default by Visual Studio you should be fine, provided you recompile everything with xbuild.
At the moment there are some minor differences in the CIL that is outputted by msbuild and what the mono VM can run.
Just run xbuild in the root directory of your solution or project. It will detect the .sln/.proj file and build everything.

I have made a project in VS2019. I have the same project in .NET Core and .NET Framework. I use a COM reference in my project. I would like to migrate these projects to Pi4.
A simple Hello World project (.NET Core) is running successfully on the Pi4 machine. However, when I try to run my project (.NET core or .NET Framework) it does not run on the Pi4. It says COM is not supported.
I tried to build the project using MSBuild in my Windows environment after looking for solutions in Google. I also see a similar error here. The error is: error : MSB4803: The task "ResolveComReference" is not supported on the .NET Core version of MSBuild. Please use the .NET Framework version of MSBuild.
The .NET Framework project also gives a similar error.
error MSB4028: The "ResolveComReference" task's outputs could not be retrieved from the "ResolvedFiles" parameter. Object does not match target type.
Does anyone have similar issues?

According to the above link. The employee of Microsoft is saying they can not give solution in the near future.
Set the Projects to x86 for them to build the Interop, the Interop created still could not be used in x64 runtimes.
Add the COM Reference to the Core project, Build it and you will get an Interop.YourCom in the bin/x86/core/debug folder.
Remove the COM reference, and re-add the Interop, it will be put into the Assemblies Dependencies, and MSBuild will work.
My MSB4803 was from a WIXInstaller project, for ADOX, and Microsoft.Office.Interop.Access.Dao
I stumbled upon this question many times and I experienced the same several times in different projects. It doesn't matter if it is Visual Studio 2019 or 2022 and the version of the build, unless you are working with the old MSBuild in a legacy environment, the COM Reference doesn't work. It is always safe to build it in the command line to understand if anything in the VS environment works. I don't truly understand why Microsoft let you make those references in the Visual Studio environment when they will not work nearly anywhere else.
There are some workarounds that might or might not work but if your code is already pointing at a COM library there is no much to do. You can install the NuGet package which is going to pass the build stage and remove the COM reference.
Install-Package Microsoft.Office.Interop.Excel -Version 15.0.4795.1001
The NuGet package has some differences at the types level that you will need to fix (the COM reference allows you to get specific types instead of objects from the cells values)
In any case, you will need the COM installed in the server, there is no workaround that issue.
I wouldn't say I like this error message or the link it shows on how to fix it, to be polite.... ;-);
I figured it out and thought as there are a lot of answers that are not helpful to share mine. What I did is update your command to force the use of msbuild.
dotnet msbuild -v:normal "FullOrRelativePathTo\MyProject.csproj" -p:Configuration=RELEASE
If that fails, try:
"C:\Program Files\Microsoft Visual Studio\2022\Enterprise\MSBuild\Current\Bin\msbuild.exe" "PathTo\Project.csproj" /p:Configuration=RELEASE
I know I'm late to the party, but here is a workaround working for me when I want to use Office Interop in .NET (Core):
Create an empty .net Console app (I'm using Rider and .NET 7)
Build it with the default MSBuild (17.0 in my case at the time of writing)
Add Interop references to the project file (I don't use Nuget, only generate these in a dummy .NET Framework project while adding COM references to Office libraries), eg.
<ItemGroup>
<COMReference Include="Excel">
<Guid>{00020813-0000-0000-C000-000000000046}</Guid>
<VersionMajor>1</VersionMajor>
<VersionMinor>9</VersionMinor>
<Lcid>0</Lcid>
<WrapperTool>tlbimp</WrapperTool>
<Isolated>False</Isolated>
<EmbedInteropTypes>True</EmbedInteropTypes>
</COMReference>
</ItemGroup>
Change the solution MSBuild version to 4.0
Try to build the solution, but the project will not even load properly due to an outdated MSBuild version
Revert the MSBuild version to the default one
Build the project - success! (this is the magic part, I can't explain it :P)
I have to continue a program witch have been coded with Visual Studio and the framework .NET framework 4 but the thing is : I have a macbook.
After many researches I have found that by using Mono it was possible to code in vb.net with a mac. However, the project is working on Windows computer but I get this warning:
"warning MSB3256: No assemblies were read in from the redist lists. A TargetFramework profile exclusion list could not be generated."
and this error:
"error MSB6006: "vbnc.exe" exited with code 1"
So I'm guessing that he doesn't recognize that mono should replace .NET framework. I am executing the code with MSbuild, maybe that is the issue?
Unfortunately you are stuck.
Microsoft would like to bring C#/VB and .NET Core to Mac via Visual Studio for Mac, so you should not attempt to bring any .NET Framework projects to Mac via Mono any more.
This warning is more critical to VB developers, as Mono's VB support (vbnc.exe is Mono VB compiler) is experimental and does not support all VB latest features.
However, for .NET Core development, VB is also not yet ready to be used, and should be available in a few months when Microsoft ships .NET Core 2.0.
You can definitely play with VB by using .NET Core 2.0 Preview build,
https://www.infoq.com/news/2017/05/netcore2preview
But then you cannot use VS for Mac, and have to use an editor such as Visual Studio Code.
For some reason, Mono uses vbnc by default although there is a Roslyn-based VB compiler built-in to Mono, vbc. Interestingly, vbnc is even not being installed with mono-devel package and it still being used by default.
If you installed vbnc and started to get this message:
"error MSB6006: "vbnc.exe" exited with code 1"
you need to instruct Mono to use vbc instead and your code will build. The most reliable way to do it is to set it per project, by adding the following XML to your vbproj file:
<PropertyGroup>
<VbcToolExe>vbc</VbcToolExe>
</PropertyGroup>
The code should be placed inside the root <Project> tag.
There are two NuGets offered by Microsoft for Typescript.
Compiler
MsBuild
I have a visual studio project that I want to run on an old build machine that does not have a current Typescript installed (It is running TFS Build 2010).
But I need to build my project with a new version of Typescript.
Do I need the compiler or msbuild nuget? (Or are neither of them going to work for what I need?)
Update: I tried the MsBuild version and it took my working project and broke it. I got a ton of compiler errors. (Cannot find name.... errors).
We're using Cruse Control to manage our build process.
AS we convert vs2008 projects to vs2010, we're leaving the target framework set at 3.5 for web and class library projects.
At this point we're not going through and converting all our solutions to vs2010; not if we don't have to.
I recently updated the MSbuild project files that cruise control uses to point at MSBuild 4.0 so our build process would be able to build vs2010 projects.
C:\windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe
All was well until a web project that was targeting the 4.0 framework was committed.
At which point this error popped up:
CS0433: The type 'System.Web.Routing.RouteCollection' exists in both c:\Windows\Microsoft.NET\assembly\GAC_32\System.Web\v4.0_4.0.0.0__b03f5f7f11d50a3a\System.Web.dll and c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Web.Routing.dll in Global.asax.cs(15, 43)
At which point I became aware of the Windows/Microsoft.NET/Assembly folders.
Now... All the MSBuild projects, even though they were using MSBuild 4.0, still had the tools version set at 3.5.
So why was a 3.5 targeted build looking at the new 4.0 assembly folders and finding this conflict? Probably because I was using MSBuild 4.0. But if I can change the toolVersion that MSBuild uses, you'd think I can tell it to target 3.5 without worrying about these potential conflicts.
To resolve this issue, I went to the relevant MSBuild project files that cruise control uses and changed their toolsVersion to 4.0. This got passed that conflict error. But now everytime it tries to build a project that's in a solution that we haven't yet converted to a vs2010 project, it breaks with an error like this:
MyProject.csproj in SomeFilePath:
LC0000: 'Could not load file or assembly or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.' in LC(0, 0)
If I open the solution that contains that project in Visual Studio 2010 and do the conversion, build it and commit that and force another build, I get passed that error only to find that another not yet converted project is tossing that same error.
So now I am for sure using MSBuild 4.0 and for real targeting the 4.0 framework. Why can't 4.0 build 3.5 projects or vs2008 solution projects?
The issue is that you have migrated part of your projects to to visual studio 2010. Any 2008 project that references a 2010 project (by project reference) will give you this compile time error. Try updating all .csproj files to 2010 and try rebuilding again.
Is it possible to build Visual Studio solutions without having to fire up MonoDevelop?
Current status (Mono 2.10, 2011): xbuild is now able to build all versions of Visual Studio / MSBuild projects, including .sln files. Simply run xbuild just as you would execute msbuild on Microsoft .Net Framework. You don't need Monodevelop installed, xbuild comes with the standard Mono installation.
If your build uses custom tasks, they should still work if they don't depend on Windows executables (such as rmdir or xcopy).
When you are editing project files, use standard Windows path syntax - they will be converted by xbuild, if necessary. One important caveat to this rule is case sensitivity - don't mix different casings of the same file name. If you have a project that does this, you can enable compatibility mode by invoking MONO_IOMAP=case xbuild foo.sln (or try MONO_IOMAP=all). Mono has a page describing more advanced MSBuild project porting techniques.
Mono 2.0 answer (2008): xbuild is not yet complete (it works quite well with VS2005 .csproj files, has problems with VS2008 .csproj and does not handle .sln). Mono 2.1 plans to merge the code base of mdtool (MonoDevelop command line build engine) into it, but currently mdtool is a better choice. mdtool build -f:project.sln or man mdtool if you have MonoDevelop installed.
for now as per August 2017 we can use
msbuild
command as xbuild is depreciated.
xbuild now supports solutions and projects, both VS2005 and VS2008.
I think you are looking for xbuild:
