How to setup ASP.NET Web Application with Docker container

I have followed the installation instructions found here: https://azure.microsoft.com/en-us/documentation/articles/vs-azure-tools-docker-edit-and-refresh/
and made an empty ASP.Net hello world project. I keep getting this error when I try to build my project:
Error MSB3073 The command "powershell -ExecutionPolicy RemoteSigned .\Docker\DockerTask.ps1 -Build -Environment Debug -Machine 'default'" exited with code 1. HelloWorld C:\dev\HelloWorld\src\HelloWorld\Properties\Docker.targets 37
Upon further digging I get this error:

========== Build: 0 succeeded or up-to-date, 1 failed, 0 skipped ==========
I am using Visual Studios 2015 on Windows 10 64bit.

The problem was my working directory was set differently than the default settings. By using the get-location command I was able to figure out where the working directory was and give it the relative path from that directory.
HelloWorld\src\HelloWorld\Docker\DockerTask.ps1

Rightly pointed out by SirJackovich.
The issue was due to a mis-pointed folder path given to msbuild.
To check out what path to modify, follow these steps:
In Properties\Docker.targets,
a. Temporarily change DockerBuildCommand to <DockerBuildCommand>powershell get-location</DockerBuildCommand>.
b. Temporarily change DockerCleanCommand to <DockerCleanCommand>powershell get-location</DockerCleanCommand>.
c. Run build having Docker build target selected (instead of 'IIS Express').
d. From the trace output in the Output window, it will print the folder which is the root for execution. For example, c:\folder1 is the root execution folder for powershell.
e. Lets say DockerTask.ps1 is located in c:\folder1\MyApp\src\App1\DockerTask.ps1. Modify the DockerBuildCommand command within Properties\Docker.targets to point to MyApp\src\App1\DockerTask.ps1. Also Modify the DockerCleanCommand command to point to MyApp\src\App1\DockerTask.ps1.
powershell -ExecutionPolicy RemoteSigned MyApp\src\App1\DockerTask.ps1.ps1 -Build -Environment $(Configuration) -Machine '$(DockerMachineName)' -ClrDebugVersion VS2015U2
powershell -ExecutionPolicy RemoteSigned MyApp\src\App1\DockerTask.ps1 -Clean -Environment $(Configuration) -Machine '$(DockerMachineName)'
f. Rebuild the solution.
This will deploy the image to the default docker environment within docker-machine.

VSCT.exe Could not load file or assembly

I am trying to build a Visual Studio Package from the command line and running into problems.
The project builds perfectly inside the Visual Studio environment, both release and debug. I am just trying to get the project to build through command line as well. Other projects, not Visual Studio Package projects, build fine. The problem is the introduction of the VSSDK.

I did see these articles, the first of which helped the most and got me past the previous error and onto this error:

Thoughts?

I had faced similar problem and here's how I solved it.
Few facts before that:
1) VSCT.exe is a 32-bit exe. That's the only version which is shipped. You can confirm that by locating the exe listed in the error message and running "dumpbin /headers vsct.exe" and see that it's a x86 (or 32-bit) binary.
2) A 64-bit exe/dll cannot load a 32-bit binary. And if tried gives this "incorrect format" exception which you are seeing in your exception details.
3) MSBuild.exe ships as both 64-bit and 32-bit binaries.
Answer:
This error will happen if you use 64-bit MSBuild.exe to compile any project containing VSCTCompile target. The reason is VSCT.exe is a 32-bit exe and you are trying to call that from 64-bit msbuild.exe.
Fix:
To fix this, you should either explicitly use 32-bit msbuild.exe or open a 32-bit command line. Here's how you do that: http://www.tipandtrick.net/how-to-open-and-run-32-bit-command-prompt-in-64-bit-x64-windows/
If you run msbuild from 32-bit command line window then your build should succeed.

Packed Excel Addin not working created using Excel DNA c#

I have an AddIn created using Excel DNA c#.
Everything works fine.
I've packed the required dll's in .dna file my dna file is as follows
<DnaLibrary RuntimeVersion="v4.0" Language="C#">
<ExternalLibrary Path="ExcelAddInClient.dll" Pack="true"/>
<ExternalLibrary Path="Newtonsoft.Json.dll" Pack="true"/>
<ExternalLibrary Path="System.Net.Http.Formatting.dll" Pack="true"/>
<ExternalLibrary Path="AuthenticationDll.dll" Pack="true"/>
</DnaLibrary>
when i double click the packed filed from Release folder it works fine.but if i copy that xll file to some other location its not working.It doesn't show any Error but It doesn't shows the Desired Output as well.
I am not geting why???

Only the Excel add-in assembly should be referenced using the ExternalLibrary tag in the .dna file.
All other assemblies should be using Reference.
E.g.
<DnaLibrary RuntimeVersion="v4.0" Language="C#">
<ExternalLibrary Path="ExcelAddInClient.dll" Pack="true"/>
<Reference Path="Newtonsoft.Json.dll" Pack="true"/>
<Reference Path="System.Net.Http.Formatting.dll" Pack="true"/>
<Reference Path="AuthenticationDll.dll" Pack="true"/>
</DnaLibrary>

You are probably missing some dlls, or other necessary files. Look in the release folder, and see what else is there.
You could try copying all of the other files along with the packed xll, and then deleting these other files one at a time to see which ones are necessary. Then add these extra necessary files into the dna file.
Also, did you know that you can debug into Excel? Use "Debug"/"Attach to Process", from Visual Studio, and connect to Excel. Then open the xll from Excel. This will hopefully show you the error.

In my case, I worked out the issue by looking at the output of the compile step.
View..Output should have no obvious errors. This is what it should look like:

========== Build: 1 succeeded, 0 failed, 15 up-to-date, 0 skipped ==========
In my case, it was printing many null reference exceptions in the build output.
It turned out that I had created a console application rather than a class library, and when the NuGet package was added, it created the .dna file pointing to ExcelDNSA2.exe, rather than ExcelDNSA2.dll.
Fix this, and everything worked like a charm.

As mentioned by Mark, you are probably missing some of your dlls, or they aren't being included in the packing.
I've found that you really need to pay attention to the output of the build commands if things aren't working as expected.
The dlls will need to either exist, and be registered on the deployment machine, or will need to be included in your Visual Studio output directory so that the packing includes them. If they can't be found it doesn't flag any error to Visual Studio, it just tells such in the output window.

Wix installer build failure : error CNDL0103: The system cannot find the file

I am trying to create a Wix CustomActions Assembly to set installer properties at msi installation time for my VS2012 c# solution. In the IDE when I right click and build the installer for the web service (OU.Curriculum.ProductService) I get the following error:

Here is my solution setup:
I'm struggling to understand why "VantageInstallerCustomActions_Generated.wxs" is being requested and causing the error as I have not included it. I can see it in the output but have no idea what has caused it to be added to the candle.exe cmd line. Any ideas how to remove it ?
Update: I believe it may have something to do with my OU.Wix.targets file:

Problem with building with csc task in Ant

I have an ant build target using csc:
<target name="compile">
<echo>Starting compiling ServiceLauncher</echo>
<csc optimize="true" debug="true" warnLevel="1"
unsafe="false" targetType="exe" failonerror="true"
incremental="false" mainClass = "ServiceLauncher.Launcher"
srcdir="ServiceLauncher/Launcher/"
outputfile="ServiceLauncher.exe" >
<reference file="libs/log4net.dll"/>
<define name="RELEASE"/>
</csc>
</target>
When I run it, the following exception comes up:
csc failed: java.io.IOException: Cannot run program "csc": CreateProcess error=2, The system cannot find the file specified
However, it runs without the exception but never correctly builds the .exe file, when I manually add in an empty ServiceLauncher.exe.
How can I correctly build this .Net project "ServiceLauncher"?

My guess is that csc.exe is not on the execute path.
From the documentation for the csc task:
csc.exe on Windows or mcs on any other platform must be on the execute path, unless another executable or the full path to that executable is specified in the executable parameter
